Taavet Hinrikus
Taavet Hinrikus is a prominent European tech entrepreneur-turned-angel investor, best known as the co-founder of Wise (TransferWise). Hinrikus, originally from Estonia, was Skype’s first employee before co-founding TransferWise in London in 2011. Under his leadership (as CEO then Chairman), TransferWise revolutionized cross-border finance and reached a multi-billion valuation. After Wise’s success (it went public in 2021), Taavet Hinrikus shifted focus to investing and supporting other startups. He has become an “operator angel” who backs early-stage European founders, particularly in fintech and software, bringing his experience in scaling a fintech unicorn. In 2022, Hinrikus teamed up with Teleport co-founder Sten Tamkivi to launch a new VC firm called Plural, a €250 million fund “built by founders” to invest in Europe’s next generation of tech companies. As an individual angel, Taavet has made personal investments in startups like Bolt (ride-hailing, Estonia), Mirror (US fintech), Zego (insurance) and many others, often taking advisory roles. He is known for his hands-on mentorship style – for example, he has provided guidance to Wise alumni starting companies and frequently advocates for Baltic and European tech on the global stage. Taavet also serves on various boards (e.g. he was on the board of Nasdaq’s Estonia arm and advisory boards of fintech companies) and was a special adviser to the UK government on fintech. In the Europe Startup Guide, Taavet is described as an angel “investing as an operator-angel in European fintech and software,” focusing on pre-seed to Series A deals. His journey from founding a $10B fintech company to re-investing in the ecosystem has made Hinrikus an influential figure. Not only does he bring capital, but also credibility and connections – helping younger European startups navigate growth and international expansion. In essence, Taavet Hinrikus exemplifies the new wave of successful European founders who “pay it forward” by fueling the next cohort of startups.
