Attio vs Close: which CRM is actually right for you?

Attio is a modern, data-model-first CRM built for operators who want flexible objects, native enrichment, and a Notion-feeling interface. Close is an outbound-first sales CRM with a native dialer, email, and SMS sequencing baked into the seat cost. This is the honest side-by-side so you can pick the right tool.

Why buyers are here

Attio vs Close: what buyers actually weigh.

Attio and Close show up on the same shortlist more often than either vendor would acknowledge, but they are not direct substitutes. Attio is a flexible-schema, operator-centric platform that assumes a RevOps or founder-operator is going to build the data model around the business and that enrichment, workflow, and reporting will be configured per-team. Close is a sales execution tool that assumes a rep is going to pick up the phone, send a sequence, and work a lead inbox from the top down. One is schema-flexible and inbound-shaped. The other is per-seat predictable and outbound-shaped. Picking the wrong one is a two-year mistake because the migration cost on either side is real. Here is what buyers actually come looking for when they type "attio vs close" into a search bar, and the honest answer for each.

Pricing shape

Two different per-seat ladders with different ceilings.

Attio and Close both charge per seat, but the shape differs. Attio has a free tier for very small teams, a Pro tier that unlocks workflows and reporting, and higher tiers that add enrichment credits, advanced permissions, and dedicated support. Close charges across four tiers with the dialer, email, and SMS tooling baked into the seat cost from the Startup tier up. Attio bills can jump when you turn on enrichment or add workflow seats. Close bills stay flat per seat but the per-seat number is higher than Attio Pro for the same team size.

Outbound motion

Flexible-schema data layer versus native dialer.

Close ships a native power dialer, predictive dialer on the top tier, email sequencing, and SMS sequencing in the same UI reps live in all day. Attio ships calling via integrations (Aircall, Dialpad, Ring) rather than natively, and its sequencing is lighter and partner-powered rather than a first-class dialer-sequence engine. If the daily driver is a rep working through a call list, Close carries the heavier half of the comparison. If the daily driver is an operator building views, workflows, and enrichment pipelines, Attio carries the heavier half.

Data model

Flexible-schema versus fixed sales objects.

Attio treats every object as a first-class record: companies, people, deals, custom objects, and relationships between them are all configurable. Operators can add fields, reshape pipelines, build linked record references, and surface views that look like a spreadsheet, a kanban, or a timeline. Close has a cleaner, more opinionated sales schema (leads, contacts, opportunities, activities) with less flexibility but a lower learning curve. For teams whose business shape does not match a classic sales CRM, Attio wins. For teams whose business IS a classic sales pipeline, Close is cleaner.

Time to value

Who is going to configure this?

Close onboards in days. A sales manager can set up pipelines, import leads, build sequences, and get reps dialing inside a week. Attio onboards in days too if you accept the defaults, but the real power lives in the configurable data model and workflows, which rewards a RevOps hire or founder-operator who is willing to design the schema around the business. Both can be run without a certified admin. Attio rewards one more than Close does.

Team size fit

Where each tool breaks.

Close is beloved for 2 to 50 person sales teams and feels thin past 100 seats, particularly on cross-object reporting, complex permissions, and enterprise RevOps workflows. Attio was built for the modern operator-led team and scales further on data model flexibility, but its reporting, forecasting, and governance surfaces are still maturing relative to Salesforce or HubSpot Enterprise. Many teams jump off Close to a bigger CRM around the 50 to 100 seat mark; Attio tends to stretch further because the data model can bend.

Enrichment and research

Native enrichment versus bring-your-own.

Attio ships native enrichment on every record: company data, people data, LinkedIn-shaped signals, firmographic details, and research-ready lists all without an external tool. Close does not ship native enrichment; teams bolt on Clearbit, Apollo, or ZoomInfo and sync in. If your motion depends on inbound signal routing, account research, or expansion plays based on firmographics, Attio wins by default. If your motion is cold calling an uploaded list, this stops mattering.

Where Attio wins

Attio is the better pick when the data model matters more than the dialer.

Attio was never designed as a sales execution tool with a dialer bolted on. It was designed as a flexible-schema CRM where companies, people, deals, and custom objects are all configurable, enrichment runs natively on every record, and workflows and views are built around how the business actually operates. That inheritance shows up in the features below. If your buying motion depends on data model flexibility, inbound signal routing, native enrichment, and an interface that feels like a modern data tool, Attio is the stronger half of this comparison.

Flexible data model

Objects, fields, and relationships you can shape.

Attio treats every object as first-class and configurable. Add custom objects for partners, properties, investments, agencies, portfolio companies, or whatever your business tracks. Define relationships between objects. Reference records from other records. Surface them in views that look like spreadsheets, kanbans, timelines, or lists. Close has a more opinionated sales schema that fits a classic pipeline but does not stretch as far when the business shape differs.

Native enrichment

Company and people data on every record automatically.

Attio enriches company and people records out of the box. Add a company by domain and firmographics, headcount, industry, funding, HQ location, and LinkedIn-shaped signals populate automatically. Add a person by email and job title, seniority, and social profiles fill in. Close relies on third-party enrichment tools synced in via integrations. For account-based motions and inbound routing, Attio saves meaningful operator hours.

Modern interface

A Notion-feeling CRM reps and operators both like.

Attio ships a modern, keyboard-friendly interface with command palette navigation, inline editing, smart filters, and views that behave like a modern data tool. Operators and ICs who have used Notion, Linear, or Airtable find it familiar. Close has a cleaner, more opinionated sales UX that reps love for dialing but which can feel less flexible when the job is anything other than working a call list.

Workflow builder

Visual automations on any object.

Attio Workflows run triggers, filters, and actions across any object or custom object. Route new leads based on firmographics, auto-create tasks when a signal fires, notify owners in Slack, update enriched fields on a schedule. The builder is visual and keyboard-friendly. Close Workflows are strong for outbound cadences but are sales-scoped by design and do not reach into the custom-object layer because custom objects are not Close territory.

Views and lists

Spreadsheet, kanban, timeline, and list views on any object.

Attio views are first-class and shareable. Build a list of enterprise prospects filtered by headcount and seniority, save it, share it with the team, and watch it update as new records enter the system. Switch the same list to a kanban grouped by stage, a timeline grouped by close date, or a spreadsheet with sortable columns. Close ships smart views for sales execution but views across non-sales objects are not the thing Close does.

API and extensibility

Developer-friendly surface for the modern stack.

Attio ships a clean REST API, webhooks on every event, and an SDK that respects the flexible data model. Operators and engineers can automate record creation, enrichment, routing, and reporting with a few hours of work. Close also has a clean API, but the surface is sales-shaped. Teams building a bespoke operator surface or a tightly integrated product-signal pipeline usually find Attio more extensible.

Inbound signal routing

Lead signals, enrichment, and auto-routing on new records.

Attio shines when a new signal comes in: a form submission, a website visit, a product trial, a new company signal. The record is enriched automatically, routed by firmographics or custom logic, assigned to the right owner, and surfaced in the right view. Close does inbound capture through integrations but the enrichment and routing muscle is lighter.

Account-based motion

Named-account lists, buying-committee tracking, warm paths.

For teams running an account-based motion (ABM), Attio supports named-account lists, buying-committee tracking through linked contacts, firmographic refresh, and warm-intro paths based on relationships. Close is lead-first and opportunity-first; account structure exists but it is not the thing Close optimizes for. ABM teams usually land better on Attio.

Startup and operator fit

The CRM operators pick when they can pick fresh.

Attio has become the default pick for modern startup operators, VC portfolio teams, and ops-led growth teams building the stack fresh. The combination of flexible schema, native enrichment, and modern UX fits teams who do not want to inherit the shape of a 20-year-old sales CRM. For founder-operators, revenue-ops hires, and ops-leaning sales teams, Attio feels built for them in a way Close does not.

Where Close wins

Close is the better pick when the job is outbound SDR execution.

Close has always been built for the sales motion specifically. It is not trying to be a flexible data platform or an enrichment engine. That focus shows up in a leaner product, a cleaner daily experience for reps who dial and sequence, and tooling that gets reps productive on day two. The features below are where the Close side of the comparison lands harder than Attio.

Native power dialer

Click-to-call, voicemail drop, local presence.

Close ships a built-in dialer with click-to-call from any lead, pre-recorded voicemail drops, call recording, call transcription, local presence numbers, and a predictive dialer on the top tier. The dialer is baked into the seat cost. Attio does not ship a native dialer; teams integrate Aircall, Dialpad, or Ring. For 50 to 200 dial-a-day reps, Close is a materially faster daily driver.

Integrated SMS

Native SMS, MMS, and SMS inside sequences.

Close ships two-way SMS and MMS on the deal record and inside sequence steps. A rep can text a prospect from the lead view, log the thread automatically, and mix SMS steps with email and call steps in the same cadence. Attio does not ship native SMS; teams rely on third-party integrations. For outbound teams that want SMS as a first-class channel, Close wins.

Sequence engine

Multi-channel cadences built for SDRs.

Close Workflows chain email steps, call tasks, and SMS steps into a single multi-channel sequence with reply detection, bounce handling, and automatic completion when a prospect replies or books a meeting. Attio has sequences but they lean lighter and partner-powered rather than being a first-class dialer-sequence engine. For an outbound SDR running 200 touchpoints a day, Close feels built for the job.

Rep-first UX

The call list is the home screen.

Open Close and a smart view, a lead inbox, or a call list is the first thing you see. Lead cards show company, phone, next step, last contact, and sequence status at a glance. Reps work the list from top to bottom, dial, log, sequence, and advance. Attio has similar power but opens into a workspace view that favors operators over dial-focused reps. Reps who spend 80 percent of their time dialing usually find Close faster to live in.

Faster time-to-value for sales teams

Onboarding measured in days, not weeks.

A sales manager who has run outbound before can set up Close in a day. Define a pipeline, import leads, invite reps, port a number, launch sequences. Reps dial on day two. Attio can be set up fast too but the real power requires schema and workflow configuration, which rewards an operator. For teams without a RevOps hire, Close is the lower-effort pick.

Call reporting

Dense sales-execution reporting out of the box.

Close reports on call outcomes, calls per rep, sequence stats, win rates by source, average deal size, and the full set of activity-dense metrics a sales manager wants to see every Monday. Attio reporting is strong on operator-shaped questions (list growth, enrichment coverage, workflow runs) but lighter on classic sales-manager KPIs like dial-to-connect ratios or sequence step reply rates.

Lead inbox

The inbox-inside-the-CRM for high-velocity reps.

Close bundles email inbox, SMS inbox, and call tasks into a single inbox view scoped to the rep. One tab replaces three. Reps triage replies, dial queued leads, send a sequence step, and advance deals without switching contexts. Attio has inbox-shaped surfaces but the integrated inbox is not the daily anchor the way it is in Close.

Per-seat predictability

The bill scales with your team, not your signals.

Close charges one price per user per month on four tiers with the dialer included, no enrichment-credit escalator or add-on dialer. A team that triples its activity in year two pays the same base per seat it paid in year one. For sales-led teams whose growth comes from reps closing deals rather than from enrichment-heavy workflows, the Close pricing shape is the right shape.

Where the two are roughly even

The decision does not hinge on these features.

Both Attio and Close have shipped mature CRM primitives. For a lot of core jobs, the quality is close enough that your decision will not turn on these dimensions. If you are evaluating and someone in a vendor meeting leans hard on one of the categories below as a differentiator, discount the pitch.

Deal and contact basics

Both products do pipelines well.

Companies, contacts, leads, deals or opportunities, activities, custom fields, pipeline stages, kanban or list view, filtering, bulk edit, saved views. Both products ship these cleanly. The feature parity on the pipeline core is high enough that most reps feel at home in either tool within a day.

Email integration

Gmail and Outlook sync, tracking, templates.

Both products ship native Gmail and Outlook integrations, two-way sync, open and click tracking, and templates. Attio uses enriched contact data to surface context on each thread. Close gives a slightly cleaner inbox experience and inbox-inside-the-CRM for reps. Neither is going to be the reason you pick.

Mobile app

A pipeline in your pocket.

Both products ship competent iOS and Android apps. Pipeline view, log a call, log a note, create a deal, update a stage. Close pulls ahead on the dialer and lead-view speed. Attio pulls ahead on record browsing and enriched context. For most reps, either app is fine.

Workflow automation

Both have no-code builders.

Attio Workflows and Close Workflows both ship no-code visual builders with triggers, filters, actions, and delays. Attio is more powerful on multi-object and custom-object triggers. Close is more approachable for a sales manager building outbound cadences. For sales-side use cases both can get the job done.

App marketplace

Real ecosystems on both sides.

Attio ships native integrations with the modern stack: Slack, Zoom, Gmail, Outlook, Linear, HubSpot, Salesforce, Segment, Zapier. Close ships a focused marketplace covering the common sales stack: Slack, Zoom, Microsoft Teams, QuickBooks, Google Workspace, DocuSign, PandaDoc, Calendly, LinkedIn Sales Navigator. For sales-only use cases, both are sufficient.

Basic reporting

Dashboards, deal reports, activity reports.

For the standard reports a sales manager runs (deals won by rep, pipeline by stage, activities logged, win rate by source, average deal size), both products are competitive. Attio pulls ahead on cross-object and custom-object reporting. Close pulls ahead on activity-dense reports like calls per rep, call outcome mix, and sequence performance.

Permissions and roles

Role-based access on both sides.

Both products ship role-based permissions, visibility rules, team-level visibility, and admin controls. Attio has been building out granular workspace and object permissions; Close handles 90 percent of mid-market sales cases without a certified admin. Both tops out before Salesforce Enterprise does.

Data import and migration

CSV import, API, and dedicated migration tooling.

Both products ship CSV importers with field mapping, duplicate detection, and preview. Both ship REST APIs for programmatic data load. Attio has a slightly more polished import flow for operators comfortable with field mapping and enrichment-aware schema. Close has a cleaner CSV flow and faster time to first import for small sales teams. Both will do the job.

Common buyer scenarios

Which one wins for which team.

The honest answer to "Attio or Close" is almost always "it depends on your motion." Below are the archetypes we see repeatedly, with the honest verdict for each. If one of these describes your team, the right pick is the one in the title.

Outbound SDR team

Close wins for outbound-first SDR teams.

If SDRs and AEs source most of pipeline through cold calling, cold email, and SMS sequences, if the daily driver is a dialer and a call list, Close is cleaner, cheaper for the sales-only use case, and gets higher rep adoption. The flexible data model on Attio is not a feature if the daily job is working a call list.

Operator-led growth team

Attio wins for operator-led growth teams.

If a founder-operator, RevOps hire, or growth lead is building the stack and wants a CRM that bends around the business rather than forcing the business to bend around the CRM, Attio is the stronger half. The shared data model, native enrichment, and modern UX matter more than the dialer at that motion.

High-velocity SMB sales

Close wins for high-velocity SMB sales teams.

For teams selling into SMB with deal cycles measured in days or weeks and reps running 50 to 200 touches a day, Close is designed for that specific motion. Dialer, SMS, sequences, smart views for lead prioritization, and a fast lead inbox beat a flexible-schema platform with heavier operator chrome.

Account-based motion

Attio wins when ABM is the thing.

If the team is running an ABM motion with named-account lists, buying-committee tracking, firmographic enrichment, and warm-intro paths, Attio is the right tool. Close is lead-first and opportunity-first; the account layer exists but it is not the thing Close optimizes for.

Small team, no admin

Close wins when nobody owns ops.

A 5 to 15 seat sales team without a dedicated RevOps hire usually lands better on Close. Attio can be configured by a part-time admin but the ROI on the flexible data model depends on someone actually shaping it. If nobody is going to, you are paying for schema flexibility you will not use.

VC-backed startup

Attio wins for VC-backed, early-stage startups.

Attio has become the default pick for seed and Series A startups whose founders have operator instincts and want a CRM that feels modern. Free tier buys early runway, enrichment accelerates account research, workflows round out the operator stack. Close is the right call for the same stage team running outbound-led motion. The decision tracks the motion, not the stage.

Mid-market services firm

Close usually wins for sales-heavy services firms.

Agencies, consultancies, and professional services firms running a per-seat outbound-led sales motion with a known deal flow usually land better on Close. The pricing math stays sane, the pipeline UX is familiar to reps, and the lack of a flexible data model is not a hole for teams whose business IS a classic sales pipeline.

VC firm or investment team

Attio wins when records are companies and portfolios.

For venture firms, PE shops, family offices, and investment teams whose records are companies, deals, portfolio companies, LPs, and relationships, Attio is the right tool. Custom objects, flexible schema, enrichment, and relationship tracking are the exact job. Close is the wrong tool for this motion.

Service-business sales

Close wins for trade and local-service outbound.

For HVAC, roofing, home services, trades, and local-services sales motions where the job is call lists, voicemails, SMS follow-up, and a clean quote-to-close pipeline, Close almost always wins. Native dialer, SMS sequences, mobile pipeline for reps on the road, no operator surface area that nobody will use.

Head-to-head

Attio vs Close: the honest feature-by-feature table

The table below is a side-by-side on the dimensions buyers ask about most. "Data model" and "Native dialer" are the two rows that drive the most regret in picking the wrong one in the first place; if your motion is outbound-first and you pick Attio, you will bolt on Aircall or Dialpad within six months, and if your motion is operator-led and you pick Close, you will outgrow its fixed schema within a year. "Enrichment" and "Pricing shape" are the two rows that most often get missed in early evaluations. All values below reflect published feature sets as of 2026 and the public pricing shapes each vendor advertises.

Feature Attio Close
Pricing basis Per seat across four tiers (Free, Plus, Pro, Enterprise); enrichment credits can add to the bill Per seat across four tiers, no enrichment escalator, dialer included from Startup tier
Free tier Yes, generous free tier for small teams (limited workflows and credits) Free trial only, no permanent free tier
Native dialer No native dialer; integrates Aircall, Dialpad, Ring, and others Native power dialer, predictive dialer on top tier, voicemail drop included
SMS inside sequences Via integrations; not a native first-class channel Two-way SMS and MMS native, step inside multi-channel sequences
Data model flexibility Flexible-schema; custom objects, custom relationships, custom views across all records Opinionated sales schema (leads, contacts, opportunities, activities); limited custom object model
Enrichment Native company and people enrichment on every record out of the box No native enrichment; teams bolt on Clearbit, Apollo, or ZoomInfo
Workflow automation Visual workflow builder across any object including custom objects Workflows for outbound cadences, sales-scoped by design
Pipeline management Strong kanban + list + spreadsheet + timeline views on any object Strong smart views + lead inbox + pipeline, outbound-first UX
Reporting breadth Cross-object reporting, custom-object dashboards, operator-shaped metrics Sales reporting (call outcomes, sequence stats, win rates), lighter on cross-object
Account-based motion Named-account lists, buying-committee tracking, firmographic refresh Account structure exists but is not the primary optimization
Mobile app Workspace + enriched record browsing on iOS/Android Pipeline + dialer-focused iOS/Android app
Custom objects Yes, custom objects are first-class on paid tiers Limited, no equivalent custom object model
Integrations Native integrations with modern stack: Slack, Zoom, Linear, HubSpot, Salesforce, Segment, Zapier Focused marketplace covering the common sales stack
Admin burden Rewards an operator or RevOps hire; schema and workflows benefit from thoughtful setup Days to configure, runnable by a sales manager
The third way

Strkr: flexible schema with native dialer-ready execution.

The honest frame of Attio vs Close is that each tool wins half of the buying question and loses the other half. Attio gives you flexible schema, native enrichment, and a modern operator surface but ships without a native dialer, SMS as a first-class channel, or a sequence engine designed for high-velocity outbound. Close gives you native dialer, SMS, and outbound sequencing with predictable per-seat pricing but ships with a fixed sales schema that does not stretch, no native enrichment, and no cross-object operator surface. Strkr was built for the buyers who refuse to pick one half. One data model across CRM, Marketing, Projects, Messaging, and Products, per-seat pricing on every tier, flexible-enough schema for operators, dialer-ready architecture for reps. Here is how it answers both sides of the question at once.

Flexible custom-object model so operators can shape the schema around the business the Attio way, with linked record references and multi-object views.
Native Messaging module with SMS and MMS designed for sequence steps alongside email, BYO Twilio compatible so outbound messaging lives on the record the Close way.
Dialer-ready architecture on the same contact record so call tasks, voicemail drops, and call outcomes attach to the deal timeline without a separate tool.
Native Marketing module (email, segmentation, lifecycle automation, lead scoring) built in so inbound signals route against enriched records.
Per-seat pricing across every paid tier, no enrichment-credit escalator and no bolt-on dialer line item, so the bill scales with your team.
Projects module native on the same record so the handoff from Closed Won to delivery is a stage change, not an integration project.
Products module native for quoting, line items, and renewal clocks so proposal and quote generation is first-class, not an add-on.
Flat admin surface designed to be shaped by a founder-operator in days, not by a certified admin in weeks.

See how Strkr prices and what it ships without the bolt-on or the schema cage.

Common questions

Attio vs Close: what buyers ask.

Which is cheaper, Attio or Close?

At similar scope, Attio is almost always cheaper on paper for the base per-seat cost, especially at mid-scale (10 to 50 seats). Attio Pro per-seat lands below Close Startup or Professional per-seat. However, the Attio bill can climb once enrichment credits scale with usage, and if your motion requires calling you will add Aircall or Dialpad on top of Attio, which closes a lot of the gap. Close bakes the dialer and SMS into the seat cost, so for teams that need both halves the Close bill is often competitive once you add integrations to Attio. The honest answer is that if you want flexible schema and enrichment, Attio is cheaper. If you want outbound dialer and SMS, Close is cheaper once you factor in the integrations.

Which is better for small outbound sales teams?

Close is the simpler pick for a 2 to 15 person outbound sales team: faster to set up, cleaner UX, dialer and SMS included, sequence engine designed for SDR work. For the same size team doing operator-led growth or ABM, Attio is the better pick despite the slight setup effort, because the enrichment and schema flexibility will carry weight you cannot get in Close. For a 2 to 5 person team that wants to use a free CRM for 6 to 12 months before paying anything, Attio free is a legitimate option Close does not match.

Should I switch from Attio to Close?

Switch if your motion has shifted from operator-led to outbound-led, if the team has grown reps faster than operators, if the daily driver has become a dialer and a call list, and if the custom objects and enrichment you set up on Attio are not getting used. Do not switch if the data model matters to the business, if enrichment is a core workflow, if the team runs ABM, or if operators and ICs both live in the CRM. The migration is non-trivial and the ROI depends on how much of Attio you actually use.

Should I switch from Close to Attio?

Switch if the business has outgrown the fixed Close schema, if you have hired an operator who wants to shape the data model around the business, if enrichment and ABM are now part of the motion, or if the team is building a bespoke operator surface on top of the CRM. Do not switch if the outbound motion is still working, if the dialer is still the daily driver, if nobody is going to shape the schema. Attio can become a flexible-schema shelf if nobody designs the workflows.

What if I need both flexible data model AND a native dialer?

This is the most common honest answer: you want both halves and neither tool is a clean fit. Attio gives you the data model half with native enrichment and modern UX but requires you to bolt on a dialer. Close gives you the dialer half with a lighter data model and no native enrichment. Some teams split the stack (Attio plus a dedicated dialer like Aircall); others accept Close plus a dedicated enrichment tool like Clearbit. There are also newer CRM platforms (Strkr is one) that ship both halves on per-seat pricing with native enrichment, dialer-ready architecture, and flexible schema, which is the third-way answer when you want both without the bolt-on.

Which has the better mobile app?

Both are competent. Close is slightly faster for the pure dialer-and-lead-view loop, and reps who live in the call list usually prefer it. Attio is slightly stronger on record browsing, enriched context, and workspace views on mobile. If your reps do most of their work from the car between site visits with a phone in one hand, Close is the lighter pick. If your reps also use operator surfaces or need enriched context before meetings, Attio carries more weight on mobile. Both ship offline support, call logging on activities, voice memos, and native calendar sync. Close opens to the lead inbox or call list by default; Attio opens to a workspace. Reps who want fewer taps between opening the app and starting a call usually report Close feels faster in the hand.

Which integrates better with my stack?

If your stack is modern SaaS (Slack, Zoom, Linear, Notion, Google Workspace or Microsoft 365, Segment, HubSpot, Salesforce), both Attio and Close ship native integrations. Attio has deeper native integrations with modern operator-shaped tools like Linear, Segment, and the modern SaaS stack. Close has cleaner native integrations with sales-execution tools like Zoom, Microsoft Teams, DocuSign, PandaDoc, Calendly, and LinkedIn Sales Navigator. The real integration question is whether you need deep bidirectional sync with a product analytics tool, a billing tool, or a BI tool. Attio has deeper hooks on operations and data warehousing because the data model is flexible. Close has cleaner hooks on sales execution tools because the schema is narrower and the integration points fewer. Teams running Segment, Snowflake, or a dedicated data warehouse usually find Attio easier to pipe data out of. Teams running a lean execution stack (dialer, scheduler, document signing, Slack) usually find Close easier to wire up because the webhook surface is tight.
