About this list
Enterprise AI in Helsinki, on this page, is bought from two very different kinds of firm, and the difference is what you are paying for.
Siili Solutions and Solita both publish AI running inside regulated organizations. Siili's Bobotin agent drafts customer-service replies at LähiTapiola Finance in Finnish, Swedish and English, with a human sending every one, and Siili operates it as a managed service under an ISO/IEC 42001 certification for AI management. Solita's predictive-maintenance work for KONE covers more than 150,000 elevators with published reductions in call-outs and entrapments, and its adverse-drug-reaction application runs at the Finnish Medicines Agency.
OstraconAI works at a different altitude: marketing and sales tools configured on platforms enterprises already run—a Copilot Studio planning agent at S-Group, a reference-search assistant on Azure for Nordic Healthcare Group—with staff training as part of the handover.
Read the page as two purchases. If the system faces a regulator or runs a physical operation, ask who operates it after launch and under what certification. If the brief is a commercial team working faster inside Microsoft 365 or HubSpot, ask which outcomes were measured after go-live rather than forecast.

Expert Insight
Why enterprise fit matters
Enterprise AI fails at the surroundings, not the model: procurement, security review, model documentation and adoption budgets decide outcomes, and an agency that has cleared them before will price and plan for them unprompted.
Reference checks work differently at this scale—an agency with two documented enterprise engagements can name a buyer who survived the same internal scrutiny yours will apply.
The pilot-to-production gap is widest here: ask for case studies that describe operations and handover, because a proof of concept that never shipped is the modal enterprise AI outcome.
Frequently asked questions
3 agencies in our directory combine verified enterprise client evidence with a Helsinki base. The current top-ranked are OstraconAI, Siili Solutions, Solita — ordered by depth of documented client evidence, then our editorial scoring (portfolio quality, credibility, completeness); placement is never paid.
Published rates across this page's agencies run €45–400 per hour (median ~€65). Project totals depend on scope — the rate index at /rates breaks the computed bands down by region, country and team size.
Each listed agency has at least two documented, named enterprise clients — published case studies or engagement descriptions our research actually read, with source URLs stored per client. Logo walls without published evidence carry no weight, which is what separates this list from self-declared directories.
