About us

We build the system we wanted to use

Koala UI started as the component library behind our own products. Today 4,100+ teams ship on it.

By the numbers

We build the foundation, teams build the product

The proof is in what teams do with it: source pulled every day, engineering time saved, and finished screens shipped across every surface.

Installs a month

Component source pulled straight from the registry by teams shipping in production.

Teams have saved over four million dollars in engineering time.

Recaptured in the first year alone, no longer spent rebuilding the same primitives from scratch.

Screens shipped this year

Accessible, polished interfaces assembled across every product surface.

The team

Eight people across five countries, building the system 4,100+ teams ship on.
