Our Story
Appollo41 began as a solo studio and grew into a team that ships production software for clients and for ourselves. We went on Nostr early, then on Bitcoin alongside it, convinced the open protocols behind them are where the next web gets built. We build and run our own apps too, so we know what it takes to ship real software and keep it alive. We work as a product partner, helping you decide what to build, then delivering native mobile apps built to last.
What Sets Us Apart
Real Bitcoin and Nostr expertise
We built Primal for Android, one of the most-used clients on the protocol, plus a non-custodial Bitcoin wallet and a cryptographic remote signer, all running in production.One team, trained to one standard
Our team grew from a university course the founder built and taught. The best students came back to build with us, trained in one way of working. You get a cohesive, low-turnover team with deep product knowledge, not a rotating cast of contractors.Skin in the game
Our own apps, Finlab and Yogamaster Meditations, are live on the App Store and Play Store. We think like owners because we are.Locations (1)
