Notion → Attio: from a clever workaround to a real CRM

Every early-stage company we've worked with tried running a CRM out of Notion first. It works at the five-person stage. Then relationships get harder to trace, views can't filter across the right fields, and the whole thing turns into search-and-pray. Moving from Notion to Attio is less about data volume and more about preserving the relationship graph you've carefully built - the "which person introduced which founder to which investor" map that's actually the only real asset in your Notion.

The what

What this integration actually does

It reads your Notion databases (People, Companies, Deals, whatever schema you've drifted into), normalizes the data, resolves the relation properties (which are Notion's equivalent of foreign keys), and writes everything into Attio with the relationship map preserved. Page content (notes, meeting logs) becomes Attio activities on the right record.

The how

How we build it

1
Map Notion databases to Attio objects. Usually People → Person, Companies → Company, Deals → Deal, plus at least one custom object that doesn't have a clean equivalent.
2
Export via the Notion API - every page, every property, every relation.
3
Resolve relations: Notion relation properties become Attio record references. Bidirectional relations need special handling to avoid double-writes.
4
Convert Notion page content (rich text with blocks, embeds, toggles) into Attio-friendly activities. Meeting notes become meeting activities. Bullet lists become structured fields where it makes sense.
5
Dedupe aggressively - Notion teams accumulate duplicates because the UI doesn't punish them. Clean up at migration time.
6
Rebuild the views the team actually uses. Notion views don't translate 1:1; we rebuild them natively in Attio.

Under the hood

What lives inside the pipeline

Relation preservation - if Person A was linked to Company B in Notion, that link exists in Attio.
Page-content-to-activity conversion - meeting notes don't become one giant text blob; they become dated activities.
Property type coercion - Notion select → Attio options, Notion rollup → Attio calculated field or dropped if stale.
Assignee mapping from Notion's people property to Attio users.
Backlinks audit so the new workspace doesn't lose discoverability.

Hard-earned lessons

What we learned the hard way

Notion rollup fields rarely survive the move meaningfully. Usually they're recomputed downstream in Notion; in Attio they become fresh formula fields, not migrated data.
Notion's rich-text blocks inside cells (like meeting notes nested in a row) get lost in basic exports. You have to walk each page individually.
Relation properties without a clear inverse are the single biggest silent-corruption vector - check both sides of every relation.
Don't migrate archived/soft-deleted pages. Notion teams rarely hard-delete; you'll end up with three-year-old ghost records if you're not careful.
Images and attachments embedded in Notion pages often live on Notion's CDN with expiring URLs. Download and re-host before migration.

Case study

Emerging VC fund, 3 years of Notion "CRM"

Problem

Three years of founder intros, portfolio updates, and LP conversations lived in a Notion workspace with 14 interlinked databases. The partners could no longer answer "who introduced us to this founder in 2023" without opening seven tabs.

Solution

Full database-by-database migration with relation preservation. Founders, LPs, deals, and intros all moved with the graph intact.

Outcome

Relationship queries that took ten minutes in Notion now take one click in Attio. The Notion workspace became an archive; the team runs on Attio.

FAQ

Questions we get

Absolutely. Notion is great as a wiki / knowledge base / ops doc tool. We just move the CRM piece out. Many teams end up with a healthier Notion afterwards because it stops trying to be two things.

Doesn't change the math. Notion is still a document tool with a database feature; Attio is a CRM with a relationship engine. Different tools, different jobs.

2-3 weeks for a standard 5-10 database Notion CRM. Longer if the schema has drifted wildly (they often have).

€5k-€12k usually. Notion migrations tend to be cheaper than HubSpot ones because volumes are lower - but they need more handholding on the data-model redesign.
