Canonical by design
Your SaaS integrates once with a stable Contact model instead of every provider’s shape.
Google Contacts first · HubSpot next · More to follow
Add maintained contact sync to your B2B SaaS.
Start with Google Contacts. Add HubSpot next through one canonical Contact model. We operate OAuth, two-way updates, retries, conflict-safe writes, and provider API changes.

The abstraction test
One Contact model. Two very different systems.
Google is an address book. HubSpot is a CRM. Supporting both proves a reusable primitive—not another API wrapper.
Google Contacts first
Validate fast onboarding and reliable two-way sync against an address-book model.
HubSpot Contacts next
Pressure-test the abstraction against CRM identity, lifecycle, and ownership semantics.
Maintained behind the scenes
OAuth, retries, conflict protection, monitoring, and provider changes stay off your roadmap.
