About Polar
It’s never been easier to build, ship, and scale software. Yet, it's never been harder to monetize software. It's a bottleneck for the future.
We're building the open-source monetization platform to empower future one-developer unicorns. Going beyond great billing primitives to offer a more comprehensive platform for the next generation of developers to scale global businesses around their software.
Today, Polar is used and loved by thousands of developers from 100+ countries, and growing quickly.
