About Martin Sokk
Martin Sokk is co-founder and CEO of Lightyear, a pan-European investing platform headquartered in London. Crunchbase lists his past role as Head of Product at Wise (formerly TransferWise) and notes that he attended the Estonian Information Technology College.
He founded Lightyear with Mihkel Aamer, who is CTO. The app gives retail investors in Europe and the UK access to stocks, ETFs and money market funds. In July 2025 Lightyear announced a $23M Series B led by NordicNinja VC, Superangel and Specialist VC, which brought total funding to $58M. Invest in Estonia reports that Sokk and Aamer were named EY Estonia Entrepreneur of the Year 2026.
Public databases list a small number of angel investments, all in Estonian startups. Crunchbase records four personal investments: Montonio (pre-seed and seed), Vok Bikes (pre-seed) and bilt.me (pre-seed). NFX Signal shows Montonio's pre-seed in July 2020 and seed in August 2021, and Vok Bikes' pre-seed in January 2021.
These databases are not complete. Many angel cheques are never announced, so the real number of investments may be higher.
The AI investment on record is bilt.me, a Tallinn-based AI app-building platform. In September 2026 it raised a $700,000 pre-seed round led by Superhero Capital, with Bolt founder Markus Villig and Sokk also backing it. Sokk's own cheque size was not disclosed.
bilt.me was founded in August 2025 by Uku Joost Annus, Kevin Akkermann and Karl Kiilaspää. Its AI agent takes a user from an app idea to a native mobile app. Estonian outlet Ari Tehnoloogia reported Sokk's reasons for investing, and said he described the Wise generation of founders backing him and now backing the next one.
Public records show pre-seed and seed investments in Estonian companies. Past deals were in fintech, payments and e-commerce, plus one urban transport hardware company (Vok Bikes). bilt.me is his first deal in an AI-native product.
