Frequently asked questions
Crono scores C on Supergood's API Report Card. Crono documents a public REST API and an MCP server for contacts, companies, activities and deals. Access is real but priced to the Ultra tier at 119 euro per user per month with a five seat minimum. Auth, SDKs, webhooks and versioning are undocumented.
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.
Crono is a recent arrival. Its GitHub organisation dates to 2022, the marketing site was indexed in 2023, and the platform page describing outbound orchestration surfaced in 2025.
Common alternatives include Outreach, Salesloft, Apollo, lemlist, Amplemarket. Graded alternatives appear under "More from the report card" below.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Not that we could find. As of August 2026 there is no official Crono MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. Crono doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
