Brillian, a Finnish startup that helps large companies put AI to work, has a new majority owner. PostScriptum, the founder office of AI entrepreneur Peter Sarlin, has acquired a majority stake in the company. Brillian’s founders, employees and other existing shareholders keep a substantial minority, and the terms were not disclosed.
What Brillian does
Brillian was founded in 2024 by Tarmo Pajunen, Tatu Hautala and Jussi Järvinen. The company takes AI from strategy to daily work, covering leadership, change, knowledge and applications across a business.
Brillian runs two AI hubs in Finland and has worked internationally from day one. Most of its revenue comes from outside Finland, and its partners include Siemens, Storytel and Carnival Cruise Lines.
The deal
PostScriptum has acquired a majority stake in Brillian. The founders, employees and other existing shareholders retain a substantial minority. Neither side disclosed the price or the size of the stake.
The deal gives Brillian backing from an investor who has built and sold an AI company before. Sarlin co-founded Silo AI, which AMD acquired in 2024. PostScriptum also backs NestAI and Qutwo, and its angel portfolio includes Lovable, Legora, Tandem Health, ICEYE and Prior Labs, which SAP acquired.
The real impact of AI is determined by how it is deployed.

What comes next
The backing lets Brillian take on more and larger client engagements, expand its international presence and open new AI hubs next year. Through Foundation PS, PostScriptum also supports AI research in Finland and Europe.
Brillian plans to build a leading European AI deployment company with PostScriptum, aiming to compete globally. More AI startups are listed in the startup directory.
