Peter Sarlin’s PostScriptum now owns more than 50% of Brillian, a Finnish company founded in 2024 that helps businesses put AI to work, from strategy through to daily operations. The deal was announced on 13 November 2026. Neither side disclosed the price, the exact stake or a valuation.

No price. No percentage. No revenue figure either.

Brillian’s three founders, Tarmo Pajunen, Tatu Hautala and Jussi Järvinen, keep a stake, and so do employees and other existing shareholders. Brillian and PostScriptum called that group’s holding a sizeable minority in the deal announcement carried by Tech.eu, and Dealroom’s summary of the deal reports the same split. The math is simple: if PostScriptum holds above 50%, everyone else together holds under 50%. Järvinen is named as co-founder and CEO.

Brillian is two years old. It runs two AI hubs in Finland, says most of its revenue comes from outside the country, and lists Siemens, Storytel and Carnival Cruise Lines among its clients and strategic partners. For those clients, the promised change is capacity: the new owner is meant to let Brillian take on more and larger projects.

The other commitments carry loose dates. Brillian plans to open new AI hubs in 2027 and grow its international presence, without saying how many hubs or which countries.

“The real impact of AI is determined by how it is deployed.”

That line is Sarlin’s reason for buying a deployment firm rather than a model builder. He has been paid for the idea before: he co-founded Silo AI, which AMD agreed to buy for $665 million in cash in 2024. PostScriptum also started NestAI and Qutwo, and its angel stakes include Lovable, Legora and ICEYE.

Other investors have also been paying for the part of AI that happens after the model is built. Nebuly took a $21 million Series A to measure the return on enterprise AI, and Desible.ai closed a ₹32 crore seed plus round.

What does a majority stake with no price tell you?

It tells you that control changed hands in the deal announced on 13 November. With more than 50%, PostScriptum has the bigger vote on what Brillian does next, and the founders and staff keep a minority stake below that line.

It doesn’t tell you what Brillian is worth or what PostScriptum paid. It also doesn’t say whether the money went into the company to pay for the 2027 hubs or out to shareholders who sold.

What to watch: how many hubs actually open in 2027, where they open, and whether Brillian ever publishes a revenue or headcount number to go with its client list.
