Why teams connect Affinity and Nutshell

Run Affinity and Nutshell side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.

Two CRMs in one company is more common than anyone plans for: an acquisition brings its own system, regions or business units standardize differently, or a migration is under way and both are live. In every case, some of the same companies and people exist in both systems, and every day of manual double entry pushes the copies further apart.

Stacksync syncs Persons, Organizations, Opportunities, Field Values in Affinity with People, Companies, Activities, Tasks in Nutshell in real time and in both directions, with field-level mapping and matching on identifiers you choose. Update a record in either CRM and the other reflects it within seconds.

Common use cases

  • Push enrichment data computed elsewhere into Affinity field values on list entries.
  • Keep introductions and relationship data from Affinity aligned with outreach tools used by the team.
  • Sync Nutshell leads into a warehouse or Postgres so small B2B teams can report on pipeline without exports.
  • Push closed-won leads to accounting software to trigger invoicing automatically.

Where both track pipeline: deal visibility across systems

Deal stage and value on shared accounts stay visible from either CRM.

Post-acquisition consolidation

Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.

Migration with a parallel run

When one CRM is replacing the other, run both fully live until cutover, with no snapshot gap and no data freeze.
