Our mission

To educate and empower anyone to build a fast and accessible Web.

100% bootstrapped

We pride ourselves on building thoughtful, easy to use tools with less. We believe sustainable growth and are in it for the long haul.

Our customers are our investors.

Invested in the Web

We firmly believe in the Open Web. We help define the future of performance tooling and education beyond our organisation.

We pay it forward.
