Custom Attio integrations.

Marketplace apps for the public catalog, custom builds for one team, private integrations for sensitive workflows. If Attio doesn't talk to a tool you use, we'll wire it up.

Some of these are in the Attio Marketplace as free apps; others are private builds. Click a logo to read the docs or start scoping a custom build for your Attio workspace.

Duplicate Detection (legacy version)

Tier 1

Marketplace App

A Marketplace app is free, public, and available inside the Attio App Marketplace. Anyone in any Attio workspace can install it with one click.

This is the lowest-commitment option for the buyer and the highest-reach option for us. Attio reviews and approves the app before publication.

When this is the right fit

The integration solves a problem that's general enough for many Attio workspaces, not specific to one team's process. Authentication is OAuth or a public API key, not a vendor-account proxy.

What we've published

Duplicate Detection (legacy version) : Docs for Duplicate Detection version 1.22 and earlier. The current version runs on the Neon Deer platform with expanded detection, review, and self-serve merging.
Apollo Enrichment for Attio : Apollo Enrichment fills missing data on your Attio People and Company records using Apollo.io's database of 270M+ contacts and 60M+ companies, automatically on record creation, in bulk via list select, or on demand from any record.
HeyReach to Attio LinkedIn Activity Sync : The HeyReach app for Attio links LinkedIn with your CRM both ways: enroll Attio People into HeyReach campaigns from a record, and stream LinkedIn engagement (accepts, replies, views, tag changes) back into Attio in real time.
Calendly Sync to Attio : The Calendly Sync app pushes every Calendly booking, cancellation, reschedule, and form answer into Attio as it happens, creates People records for invitees and guests, and gives you a complete meeting history with payment and UTM context inside your CRM.

Tier 2

Custom Build

A custom build is built for one team and deployed once. This is the most common shape because your workflows are usually specific enough that a generic Marketplace app would not fit.

Scope a custom build

Common things we build

Syncs between Attio and external tools. Push data out, pull data in, or keep both sides current.
Data enrichment from Apollo, Specter, or custom APIs, automatically filling fields on your People and Company records.
Reporting and exports into Google Sheets, BigQuery, Snowflake, or your BI tool of choice.
Workarounds for Attio's native limits. When workflow credits or trigger constraints become a problem, there are usually good options.
Attio App Store submissions. We know the SDK and submission process well if you want something published.
Anything else. If your team uses two tools that should talk to each other, let's take a look.

How it works

Start with a free discovery call. We describe the integration shape we'd ship and what it would take. If we're a fit, we scope a fixed-fee build with a clear deliverable; if we're not, we point you at someone who is.

Tier 3

Private Integration

Internal-only. The integration lives in your account, not the Marketplace. We sometimes maintain it for you on a retainer.

Right when the data is sensitive, the workflow is proprietary, or the integration is too narrow to publish.

When private makes sense

You don't want competitors to see how your CRM is wired. The integration depends on an internal API you don't expose publicly. Compliance requires the integration code stay inside your stack.

Ongoing support

Private builds usually come with a maintenance plan. We keep the integration running through Attio API changes and your downstream tool changes. Optional, but most teams take it.

Setup steps, field mappings, limits, and trade-offs, documented for every integration we've shipped. If something close to what you need is already in the library, custom work can usually build on top of it.
