Life
[ edit ]
Tallinn graduated from the University of Tartu in Estonia in 1996 with a BSc in theoretical physics with a thesis that considered travelling interstellar distances using warps in spacetime .
Tallinn founded Bluemoon in Estonia alongside schoolmates Ahti Heinla and Priit Kasesalu . Bluemoon's Kosmonaut became, in 1989 ( SkyRoads is the 1993 remake), the first Estonian game to be sold abroad, and earned the company US$5,000 (~$12,987 in 2025). By 1999, Bluemoon faced bankruptcy; its founders decided to acquire remote jobs for the Swedish Tele2 at a salary of US$330 (~$638.00 in 2025) each per day. The Tele2 project, "Everyday.com", was a commercial flop. Subsequently, while working as a stay-at-home father, Tallinn developed FastTrack and Kazaa for Niklas Zennström and Janus Friis (formerly of Tele2). Kazaa's P2P technology was later repurposed to drive Skype around 2003. Tallinn sold his shares in Skype in 2005, when it was purchased by eBay . [ 13 ] [ 8 ]
In 2014, he invested in the reversible debugging software for app development Undo . [ 14 ] He also made an early investment in DeepMind which was purchased by Google in 2014 for $600 million (~$781 million in 2024). [ 15 ] Other investments include Faculty, a British AI startup focused on tracking terrorists, [ 16 ] and Pactum, an "autonomous negotiation" startup based in California and Estonia.
