We’re building infrastructure for adaptive software: software that reshapes itself around whoever’s using it.

The world is built on software that converges, one version for everyone. Our vision is a world built on software that adapts and diverges, the best version for anyone.

Our first product, Differ, explores Software as Content: people make, play and remix small apps the way they make text posts, videos, data viz or memes.

We’re still discovering what that looks like, and you’d help us find out by building it.

• We're AI-native. We build with AI tools every day, from the first sketch to what ships, which makes taste matter more, not less.
• There's no handoff. Whoever designs a thing builds it and ships it.
• Details matter. We'll happily spend a day getting one interaction to feel right.

• Help build the core of Differ: the player, the feed, the tools for making and posting, and our mascot Diffy.
• Set the visual language, aesthetic and direction of the product.
• Run your own experiments on the platform.
• Own things end to end: design them, build them and ship them.

You think by making. Someone describes a half-formed idea, and within hours you have a rough sketch, plus three variations nobody asked for. You make a lot, you’re hard on the details, and you keep the 1% that’s actually good.

• You have a good grasp of UX.
• You've made unusual, fun things just because you wanted to.
• You have strong, opinionated taste.
• You share what you make in public: you write about it, give talks or run meetups.
• Bonus: you've shipped real software as an engineer, including before the AI era.

• You need a finished spec before you start.
• You want to own one narrow slice.
• You want remote work.
• You need a visa. We can't sponsor one, so you'll need the right to work in the UK.
• You think AI is overhyped and don't want to build with it.
• You want a comfy life, not intensity and obsession.

• Salary & founding equity.
• 20% innovation time, and you own what you build in it.
• A tiny team: Noam, Iris and Jules.

Send us one thing you’ve made: a link, a repo or a video. Add a few lines on what you’d change about it now. No CV or cover letter.

Optional: links to where you share your work, like X, Instagram, GitHub, a site or anything else.
