Cal.com, Inc.is an American open-core SaaS company that provides tools for managing online appointments and bookings. Founded in 2021 by developers Peer Richelsen and Bailey Pumfleet, the company is headquartered in San Francisco, California.[1]
Overview
Cal.com operates as an open startup, publicly sharing company metrics and employee salary data.[2] The platform has been described in technology media as an open-source alternative to proprietary scheduling products such as Calendly.[3] The company employs between 11 and 50 people. [4]
Products
Cal.com offers a free plan for individual users, a self-hosted version, and several hosted subscription plans including enterprise options that provide SAML SSO and Salesforce integration.[5][6] The platform connects with major calendar services such as Google and Outlook. Its source code is available on GitHub, allowing self-hosted users to maintain control of their scheduling data and infrastructure.[7] Developers have deployed Cal.com using AWS, Docker, and Caddy to demonstrate its flexibility for private hosting.[8]
Cal.com maintains REST APIs, a set of React components called Cal Atoms, and open documentation for embedding or extending its scheduling engine.[9] Integrations include SnapCall’s use of Cal.com within Zendesk to enable in-app meeting scheduling.[10]
Technology publications such as TechCrunch and Business Insider have highlighted Cal.com's open-source model and growth trajectory.[11][12] Other tech outlets have noted its focus on compliance, data control, and open APIs as differentiators from proprietary competitors.[13] On software review platforms such as Product Hunt and G2, Cal.com has received positive feedback for its open-source flexibility and integrations, with occasional criticism related to setup complexity and calendar synchronization.[14]
History
The company was founded in 2021 under the name Calendso and rebranded to Cal.com in January 2022.[15] That year, Cal.com raised US $7.4 million in funding from OSS Capital and other investors focused on open-source technology. *VentureBeat* profiled the company among startups advancing the open-source software movement.[16]
In October 2023, Cal.com announced Cal.ai, an AI-powered voice agent that books, confirms, or reschedules meetings using workflow triggers.[17]
In 2025, Cal.com acquired Origin UI and merged it into a new holding entity named coss.ui.[18]
According to startup database Clay.com, Cal.com has raised approximately US $32 million across seed and Series A rounds.[19]
