Mika Salmi, the sole principal, drives all investment decisions with the autonomy of a single-family office structured as a corporate investment vehicle. Salmi's operator background — he built Sulake (Habbo Hotel), IRC-Galleria, and held senior roles at MTV and Creative Artists Agency — means his direct involvement mirrors that of a founder-investor rather than an institutional allocation committee. There is no public disclosure of a formalized investment committee or external advisors.

Salmi sources deals primarily through his own network in the Nordic and European technology ecosystems, a circle built over two decades as a serial founder and executive. The office does not publicly market for deal flow, and its venture positions tend to emerge from founder-to-founder introductions rather than competitive fundraise processes. In the deep-tech space, its participation in rounds like IQM Quantum Computers' 2023 Series D suggests co-investment relationships with European climate- and quantum-focused venture funds.

Legally, it operates as a Finnish corporate investment company rather than a branded family office, and Salmi himself does not use the family-office label publicly. This structure — a permanent-capital vehicle deploying a single founder's wealth — allows it to hold assets indefinitely while maintaining the lower public profile of a privately held balance-sheet investor, distinct from the multi-generational governance frameworks typical of European SFOs.

Public filings and press reports describe only direct positions — in private venture rounds, listed equities, and Helsinki-area real estate — with no documented fund-of-funds commitments. The office's lean operational structure and Salmi's hands-on investment style are consistent with a direct-only approach, though the absence of a public LP track record leaves open the possibility of undisclosed fund stakes.

The wealth originates from Salmi's exit proceeds from the consumer-internet businesses he founded or led in Finland during the early 2000s. The most prominent source is Sulake Corporation, the company behind Habbo Hotel, which at its peak served tens of millions of teenage users globally and attracted investment from Benchmark and 3i before Salmi's eventual exit. Earlier ventures include IRC-Galleria, Finland's dominant social-networking site before Facebook's regional expansion.
