Origin Story

By Peer Richelsen & Bailey Pumfleet

The Problem

Calendly was a closed-source product with limited customization. Scheduling infrastructure should be open and extensible like other critical business tools.

Building It

Launched in 2021 (originally as Calendso). Gained rapid adoption in the open-source community. One of the most starred scheduling projects on GitHub.

First Customer

The open-source launch on GitHub gained thousands of stars in days, validating the demand for an open alternative to Calendly.

What It Means

Open-source scheduling for everyone — self-hostable, customizable, and community-driven.

The Dream

To be the scheduling infrastructure that powers the internet.
