About Cronofy

Cronofy provides a secure and scalable scheduling automation platform for businesses through a unified API that integrates with major calendar services. Founded in 2014 by engineers Adam Bird and Garry Shutler, the company was born out of frustration with disconnected calendars and the manual effort required for scheduling. They developed a new architectural approach to calendar infrastructure, focusing on embedding scheduling capabilities directly into business applications while prioritizing security and privacy.

Headquartered in Nottingham, UK, Cronofy serves a global client base, with over 60% of its revenue generated in the US. The company's technology is utilized by over 180,000 organizations in sectors such as recruitment, healthcare, and professional services. Its business model is centered on providing its API and embeddable scheduling components to software developers and product teams, enabling them to build custom, real-time scheduling features into their own applications. Revenue is generated through tiered, usage-based subscription plans, including a model that bills based on the number of active users.

The platform's core service is a single API that connects with Google Calendar, Microsoft 365, Outlook, Apple Calendar, and Exchange, eliminating the need for developers to build and maintain separate integrations. Key features include real-time, two-way calendar synchronization, availability management, multi-person meeting coordination, and automated timezone adjustments. Cronofy offers robust developer tools, including white-label APIs for full customization and low-code embeddable schedulers for rapid deployment. The company emphasizes security, holding certifications such as ISO 27001 and SOC 2 Type 2, and is HIPAA compliant.
