A small studio, built to be trusted with real work

Robust Binary was founded in 2025 in Helsinki to give companies in Finland and the EU a senior engineering partner for AI and mobile projects — without an agency mark-up or a junior team behind the sales call.

Senior engineer on every project
Nine years of Android and enterprise software, most recently leading Android development for an enterprise mobility platform. The person you talk to is the person who builds it.
Based in Helsinki, hosted in the EU
Data stays inside the EU by default. Contracts under Finnish law, invoices in euros, working hours that overlap yours.
Fixed scope, weekly demos
A written quote before work starts, working software every week, and no invoice surprises.
You own the code
Everything is delivered into your own repository with documentation, so you are never locked in.
