Calendly operates an automated scheduling platform that eliminates back-and-forth emails when arranging meetings. Founded in 2013 by Tope Awotona in Atlanta, Georgia, the company provides software that allows users to set availability preferences and share booking links with others who can then select meeting times directly.

The platform serves over 20 million users globally, including customers such as Twilio, Zendesk, and LaunchDarkly. Calendly offers individual, team, and enterprise plans with features including calendar integrations, automated reminders, payment collection, and workflow automation. The company competes in the scheduling software market alongside Acuity Scheduling, Doodle, and Microsoft Bookings.

Calendly has raised $351 million in funding, including a $350 million Series B round in January 2021 that valued the company at $3 billion. The funding round was led by OpenView Venture Partners and Iconiq Capital. The company reported reaching profitability in 2020 and has maintained bootstrapped growth for most of its history before accepting external investment.
