Cronofy

Cronofy is a Nottingham-headquartered British developer-API-first calendar and scheduling-automation platform, founded in 2013 by **Adam Bird** (CEO) and **Garry Shutler** (CTO). The product is positioned for two audiences: SaaS product builders who need to integrate scheduling features (calendar availability, multi-person + multi-room coordination, video-conferencing integration) into their own applications via a unified API; and enterprise process-automation teams who need to coordinate scheduling across HR / sales / recruiting workflows. The flagship customer roster — **Wise, GoCardless, Criteo, Teamtailor, Indeed, Squarespace** — is unusually high-quality for a 29-employee API company, with 180,000+ end-companies on the platform handling 1B+ events. Compliance posture is enterprise-grade: **ISO 27001, SOC 2, GDPR-aligned, HIPAA-aligned** — the standard stack required to serve the regulated-industry portion of the customer base. UK post-Brexit jurisdiction places Cronofy in the directory's `other` ownership tier; the UK holds an EU adequacy decision so cross-border EU↔GB transfers require no SCCs. Two procurement-relevant qualifiers reduce the score from 5/5 to 4/5: public reporting indicates Cronofy has been **acquired** (the acquirer is not directly disclosed at audit and the operating brand persists in the market), and approximately **60% of Cronofy's revenue is US-based** — which strongly suggests an AWS-EU + AWS-US dual-region backend that the directory's strict-ownership CLOUD Act stance treats as material exposure for at-rest customer data. Pricing is API-tier-based with per-event usage scaling; specific EUR tier figures were not captured at audit. Best fit: product builders integrating scheduling into B2B SaaS (HR-tech, recruiting, sales, customer-success), where Cronofy's ISO 27001 + SOC 2 + HIPAA stack and stable client roster reduce procurement friction. UK + EU customers should request the DPA, the underlying hosting region map, and post-acquisition ownership disclosure directly before signing.
