About Tuomas Kosonen

Tuomas took an unusual route into venture capital, moving from law and litigation work to Nokia in-house counsel and then CFO at Rovio before its Angry Birds breakout, and he has long argued that investors need to help startups reach international markets like Asia rather than stick to local deals, with a particular eye for ambitious, straightforward founders in the Baltics and a comfort with high-tech and deep-tech ideas many investors shy away from. He looks for founders who think differently from everyone else in their field, as he did when backing ReOrbit, and he's willing to bet on a strong team even before the business model is fully worked out, like when Inventure became the first investor in Wolt—an approach that fits his own admission that he isn't a technical expert himself and instead builds his firm's strength through a mix of different backgrounds and perspectives.

Inventure is a Nordic/Baltic-focused venture fund known for its early conviction in Wolt, splitting its €400k pre-seed round and leading its second seed round, and for backing operational infrastructure like Jobbatical to modernize legacy, admin-heavy markets through automation. The firm operationalizes founder support through structured programs like onboarding workshops, small theme-based sessions, and cross-portfolio Slack communities, while its partners bring deep operator experience—from Timo Tirkkonen's technical, science-heavy company coaching since founding his first investment firm in the 1990s, to Ryan Savage's talent and sales expertise drawn from roles at Wolt and Yousician.
