Renström.

I design and build cinematic interfaces — real-time tools, motion-first product systems, and the strange edges of the web where craft still matters.

I make small, stubbornly considered things — usually for people who care a little too much about how software feels.

For the last decade I've worked the seam between design and engineering — at Linear, Stripe, and a handful of small studios — drawing interfaces in the morning, shipping them at night.

These days I work independently from a small office overlooking the river. I take on two or three projects a year, usually with founders who want a single hand on the brand, the product, and the way it moves.

Let's make
something
that lasts.

Two slots open this autumn. Brief notes are welcome — long ones are even better. I usually reply within a day.

Halocene 1.4 (sailing instrument), a small typeface called Cobalt, and a long-overdue rewrite of my own portfolio engine.
