Independent App Studio · Est. 2024

Build Stellar
Apps.

We design and engineer AI-powered mobile products that feel obvious, calm, and a little bit cosmic. A small studio, with high standards.

Three products,
obsessively made.

Every pixel, every transition, every line of copy — held to a standard we'd be proud to ship at Apple.

A studio of three, building software for the next billion creators.

Stellup is an independent app studio crafting tools at the intersection of AI, music, and daily ritual. We work in small teams, ship in long arcs, and treat our apps like instruments — tuned obsessively until they sing.

We are remote-first, design-led, and quietly ambitious. Our work is used by musicians in Lagos, students in Istanbul, and producers in Brooklyn.
