about

hartsook is a small software studio in Los Angeles.

I make games and tools. What I care about is the part that never makes a feature list — how the animation settles, what the empty state says, whether the words read like a person wrote them.

I founded hartsook and named it after the street I grew up on. I like making things.

The bird flying around this page is Tookie, inspired by the real one, who was my dad's — the last in a long line of animals he rescued during his life. He's also the star of Bird Brain.
