What Stacksync syncs in Affinity.

These objects sync between Affinity and any connected system, with field-level mapping and conflict resolution. Custom fields are picked up from the live schema where Affinity exposes them.

Lists
Pipelines (deal flow, fundraising, portfolio) that structure most Affinity data; syncs usually target a specific list.
List Entries
The membership of a person, organization, or opportunity on a list, carrying its list-specific fields.
Persons
Contact records enriched with relationship intelligence, synced with CRMs and outreach tools.
Organizations
Company records matched to accounts in other systems by domain.
Opportunities
Deal records tracked on lists and synced with pipeline reporting.
Field Values
Custom field data, either global or scoped to a list, mapped field-by-field in syncs.
Notes
Meeting and call notes synced for record-keeping in other systems.
Interactions
Automatically captured emails and meetings, read for activity reporting.
Reminders
Follow-up tasks associated with people and organizations.

Use cases

What teams run on the Affinity connector.

Affinity is bought by private capital deal teams: venture capital, private equity, investment banking, corporate VC, family offices, and asset managers. It acts as the firm's system of record for relationships and pipeline, automatically capturing data from email, calendar, and meetings, so Persons, Organizations, and Interactions accumulate there without manual entry. RevOps and platform teams then need that relationship graph available to reporting, portfolio, and outreach systems.

  • VC / PE deal teams
  • RevOps
  • Platform and portfolio operations
  • IT administrators

  1. Sync Affinity organizations and persons with Salesforce or HubSpot so investment and sales teams work from one record.

  2. Mirror deal-flow lists into a warehouse or BI tool for pipeline and portfolio reporting.

  3. Push enrichment data computed elsewhere into Affinity field values on list entries.

  4. Keep introductions and relationship data from Affinity aligned with outreach tools used by the team.

  5. Sync notes and reminders into project or task systems used outside the deal team.

  6. Replicating Persons, Organizations, and Interactions into a warehouse so the firm can analyze network coverage and deal flow outside Affinity's UI.

FAQ

Affinity connector FAQ

What can I sync with the Affinity connector?

Affinity's core objects — Lists, List Entries, Persons, Organizations and custom fields — can sync with any of 302 other systems. Every integration is real-time and bidirectional, with field-level mapping and conflict resolution.

How does Stacksync connect to Affinity?

Via REST API, authenticated with API key. Changes are detected as follows — webhook subscriptions for record events, supplemented by polling. Stacksync manages rate limits, retries, and schema changes automatically.

Is the Affinity connector two-way?

Yes. Changes made in Affinity propagate to the connected system and vice versa, in milliseconds. One-way flows are also supported when a direction should stay read-only.

How long does an Affinity integration take to set up?

Most Affinity integrations go live in minutes: authenticate Affinity and the other system, pick objects and fields, and enable the sync. No code and no infrastructure to manage.

Is Affinity data secure in transit?

Stacksync is SOC 2 Type II, ISO 27001, GDPR and HIPAA compliant. Affinity data is encrypted in transit, and a zero-persistent-storage architecture means records are not retained after a sync operation.
