One person.
Finnish grit.
Real software.
SisuMVP is a Finnish one-person AI software studio. It builds custom AI software — fast — turning ideas into real, working products so clients can validate them before investing big.
The Finnish word for grit, tenacity, getting it done no matter what. It's why working software ships — quickly, and without cutting corners on correctness.
Minimum viable product — real, working software you can put in front of real users. Not slide decks, not mockups. Something that runs.
SisuMVP — we build MVPs with sisu. Working software, shipped with Finnish determination, fast.
A validation accelerator, not a lock-in.
The client owns everything from day one — all data, all source code, full ownership. When an idea proves itself, the client can take the whole thing and hand it to a bigger company or an internal team to scale.
Our job is to de-risk decisions cheaply and fast, for the client's benefit. Test before you invest; spend big only on what's already proven.
A focused, one-person studio.
SisuMVP is a focused studio for building AI applications that have to ship and run reliably. The work spans the full stack — crawling and data engineering, vector and full-text retrieval, agentic LLM orchestration, polished streaming UIs, billing, and self-hosted deployment on infrastructure the client can own.
Based in Espoo, Finland, and registered as a Finnish toiminimi — small, fast, and accountable, with no layers between you and the person building your software.
