## About this market
Custom AI development in Helsinki splits between two consultancies with deep benches and two small firms that ship quickly. Solita has built data and AI systems since 1996 across eight countries and holds elite-tier partnerships with the platform vendors it delivers on. Siili Solutions brings a similar scale with a listed company's governance and a client list running through Finnish industry and the public sector. Against them, DevXHub and Senpai Growth Studios are small, fast and inexpensive, both publishing conversational and agent tooling, and both quoting at the bottom of the European range.

The screen that separates them is not skill but what happens after handover. Ask whose cloud account the system runs in, who holds the evaluation set, and what your own engineers could maintain without the vendor in the room. Then ask how model quality is measured and by whom — a system graded only by the team that built it is graded generously. At the consultancy end, ask specifically who will write the code rather than who is presenting; at the small-firm end, ask what happens to your delivery date if one named person leaves, because at that size the answer is a real risk rather than a formality.
