A deep-tech / hardware venture firm: Affinity to Attio migration with full QA verification

In one line. 80x migrated a deep-tech / hardware venture firm from Affinity to Attio, running a structured QA audit and verifying that ~3,200 attached files transferred correctly to Google Drive before the old system was retired.

Client & context

The client is a deep-tech / hardware VC firm moving off Affinity onto Attio. Because Affinity was being switched off, the migration had to be complete and verified before the license lapsed, companies, people, notes and every attached file across, with nothing left behind.

The problem

A migration under a hard cutover leaves no room for gaps: deal records, LP data, email mappings, fund labels and thousands of attached documents all needed to land accurately in Attio, and the transfer had to be provably complete before the source system went away.

What we built

• A full Affinity-to-Attio data migration (companies, people, notes, files).
• A structured QA audit of the transfer, tracked against a shared verification checklist so every item could be signed off.
• Verification that ~3,200 files had transferred correctly to Google Drive.

How we did it

We worked the migration as a QA-led process: a shared checklist drove verification field by field, covering file mapping, email and domain mapping, fund labelling and LP records. The priority was proving a complete, verified transfer before the Affinity license lapsed, so file integrity against Google Drive and record-level accuracy were checked systematically rather than sampled. The team was able to keep working in Attio throughout, and we provided dedicated support through to full sign-off, with the agreement that no field or feature would change without notice.

Outcome

• A verified Affinity-to-Attio migration, with ~3,200 files confirmed in Google Drive.
• The team working in Attio while verification completed, with dedicated support to sign-off.

Takeaway: An Affinity-to-Attio migration delivered under a hard cutover, with a shared QA checklist and ~3,200 files verified in Google Drive before the old system was retired.
