About Cal.com
Cal.com is the leading open-source scheduling infrastructure platform, enabling businesses and developers to build appointment booking and calendar management into any application. Founded in 2021 and headquartered in San Francisco, Cal.com offers both a hosted SaaS product and a self-hostable open-source version under the AGPLv3 license. The platform integrates with Google Calendar, Outlook, Zoom, Stripe, and hundreds of other tools via a composable API-first architecture.
Business Model & Competitive Advantage
The company raised $25 million in Series A funding in 2023 from Fuel Capital and other investors, accelerating its enterprise roadmap and expanding the open-source community. Cal.com's GitHub repository has accumulated over 30,000 stars, making it one of the most popular open-source scheduling projects. By 2024-2025, the platform serves individual creators, startups, and enterprise teams including use cases ranging from sales call booking to healthcare appointment management.
Competitive Landscape 2025–2026
