Special Projects on AI resilience at the OpenAI Foundation. Tech entrepreneur, Helsinki (currently) & San Francisco (starting ~Sept 1, 2026). I work on efforts to maximize the benefits of AI while minimizing its risks. Story of me and AI here.

Previously: One of the founders of the local commerce platform Wolt, operating in 30+ countries with 50M+ customers, acquired for $8B by DoorDash in 2022 (I left the company in 2024 after 10 years). 

On the hobby side, I’ve been the founder of both the largest functional fitness competition in Finland, WOD-liiga as well as Salmisaaren Saliseura, the cosy CrossFit Open Gym in Salmisaari, Helsinki. 

My Instagram gives an idea about my non-work life.

Resume here.
