Crono has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Crono is a European B2B sales platform that combines prospecting data, multichannel sequencing across email, DMs and calls, and AI agents into a single outbound execution layer.
Sales technology for mid market B2B revenue teams. Teams import or sync accounts and contacts from HubSpot, Pipedrive or Salesforce, enrich them with Crono email finder credits bought self serve under Settings then Add ons, and build sequences with multiple touchpoints across email, DMs and calls.
Crono states it is trusted by 300 plus market leading companies and reads as an emerging European vendor rather than a category incumbent, with no independently sourced customer roster or market share figures available.
Crono holds the outbound record: prospect and account lists with enriched contact data, multichannel sequence definitions and step history, task queues, call and email activity logs, and deal linkage back to the connected CRM.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
