An Attio expert is a consultant or agency that designs, migrates and automates Attio workspaces for you: the data model, the import from HubSpot or Salesforce, the integrations and the reporting. Attio is fast to start on, but a CRM is only as useful as its objects, its data hygiene and what feeds it. Teams that skip the design work end up with a clean-looking workspace nobody trusts.

This guide compares 9 Attio agencies and experts in 2026, using Attio's own Experts directory, each firm's website and published pricing, all checked on 2026-10-21. You get a comparison table, review counts, entry prices where firms publish them, and a framework to pick one.

Disclosure: ManasFlow wrote this guide and ranks itself first. The reason is scope: we set up Attio and build the automation around it (enrichment, outbound, n8n jobs, AI agents) in one team, and we run Attio as our own CRM. ManasFlow is not listed in Attio's Experts directory. If you want a directory-listed firm, a VC-specific build or the cheapest fixed sprint, one of the other entries below will fit better, and we say which.

Best Attio agencies: a brief overview

  • ManasFlow: Best overall Attio agency for automation-first teams: Attio setup plus the enrichment, outbound and AI workflows that feed it, built by one team.
  • novlini: Best for Attio plus an outbound stack: the most-reviewed firm in Attio's directory, with Clay and lemlist work alongside the CRM.
  • Neon Deer Data Labs: Best for data-heavy builds: warehouse pipelines, complex migrations and its own dedupe tooling for Attio.
  • Sideways CRM: Best for investment and advisory firms: fixed published pricing and a focus on VC, advisory and brokerage teams.
  • dialed technologies: Best for custom code: native Attio SDK apps, product-usage syncs and API work.
  • 5050Growth: Best for AI deal-flow agents: fixed one-week sprints for VC, PE and startup teams.
  • Crawl Walk Run: Best for APAC teams leaving HubSpot or Salesforce, with fixed-price phases.
  • Revautex: Best for workshop-first projects: a 90-minute process workshop before any build.
  • Craftt: Best for a fast fixed-price start: a published 7-day sprint at $2,500.

Reviews on Attio's Experts directory

Source: attio.com/experts profile pages, checked 2026-10-21. Every listed firm showed a 5.0 rating, so review count is the more useful signal. ManasFlow is not listed in the directory.

Quick takeaways

  • novlini and Neon Deer Data Labs are the two firms carrying Attio's Elite label, with 68 and 48 directory reviews.
  • Craftt and Sideways CRM are the only firms here that publish prices: a $2,500 seven-day sprint and setup from £3,500.
  • Attio's directory uses three labels, Elite, Advanced and Core, and every firm we checked showed a 5.0 rating, so the tier and the number of reviews tell you more than the stars.

1. ManasFlow, best overall Attio agency for automation-first teams

ManasFlow is an AI automation agency that builds go-to-market systems, and Attio is the CRM we run our own pipeline on. That matters for one reason: we have lived with the same objects, lists and API limits you will. Our Attio agency service covers the workspace itself (objects, attributes, lists, views, permissions), the migration from HubSpot, Pipedrive or spreadsheets, and then the part most CRM projects leave out: the systems that keep Attio full of accurate data.

That second half is where we spend most of our time. We build enrichment that writes verified company and contact data into Attio, outbound sequences in Instantly and HeyReach that log replies back to the right record, and scheduled n8n jobs that dedupe records, flag stalled deals and post a weekly digest to Slack. The CRM hygiene automation workflow shows the pattern step by step.

Key features

  • Attio data model design, migration and permissions, scoped before any import
  • Enrichment and scoring pipelines that write into Attio with validation and logging
  • Outbound wiring: Instantly and HeyReach replies logged to the right Attio record
  • n8n jobs for dedupe, stalled-deal alerts and lead routing (custom n8n automation)
  • AI agents for research and record updates, with every write checked before it lands
  • Option to place an embedded GTM engineer through hire a GTM engineer

Best for

  • B2B SaaS and agency teams that want Attio plus the outbound and enrichment that feed it
  • Teams moving off HubSpot or Pipedrive who also want the old automations rebuilt properly
  • Founders who want one team for the CRM and the GTM plumbing around it

Pricing

  • Custom quote after a discovery call
  • Embedded GTM engineer placement from $60,000 a year, with a 90-day replacement guarantee

Pros

  • One team covers Attio, enrichment, outbound and n8n automation, so nothing gets lost between vendors
  • We run Attio, Instantly, HeyReach, Unipile and n8n for our own pipeline, so the advice comes from daily use
  • Delivery in English, French and Arabic

Cons

  • Not listed in Attio's Experts directory. If a directory badge is a buying requirement, pick novlini, Neon Deer or another listed firm
  • No published fixed-price package. Craftt or Sideways CRM are easier to budget for a simple setup

2. novlini, best for Attio plus an outbound stack

novlini is a GTM and CRM consultancy based in Paris with an Elite label and 68 reviews in Attio's directory, the most of any firm we checked. Its site describes a six-phase process (discovery, audit and mapping, roadmap, build, enablement, ongoing partnership) and lists 22 people across GTM engineering, CRM architecture and automation.

The firm's Attio work sits next to outbound tooling: its site names Clay, lemlist and Customer.io, and it runs HubSpot to Attio migrations. That makes it a good match for teams that want the CRM and the prospecting stack designed together.

Pros

It handles Attio implementation, migrations from Affinity, HubSpot, Pipedrive, Salesforce, Copper and spreadsheets, and custom pipelines built with dbt, Prefect and dltHub.
