SMOK Ventures
Founding Partner

Engineer turned Entrepreneur turned Investor. Geek. Film buff. Basketball fan.

I’m a founder and partner at SMOK Ventures where we fund early stage startup founders (checks from €50k to €1M) based in Poland but with global vision. We focus on software companies in gaming, AR/VR, fintech, martech and AI.

At ReaktorX pre-acceleration program ( I look for first-time founders who understand their industry and want to build a sustainable company. Read more at TechCrunch (

Previously I co-founded Filmaster.TV (acquired by Samba TV in 2015) which provided Netflix-like personalization and analytics solutions for the entertainment industry helping television and online video providers rapidly capture and analyse user preferences in order to deliver a comprehensive picture of the audience and drive incremental admissions / viewership. After the acqisition by Samba TV I helped the company bring its products to the European markets and scale the team from 4 to 40 in four years.

I helped found Startup Poland, a leading technology think tank in Poland and the community voice of Polish startups. I’m currently chairman of the board of the foundation.

I also co-founded, a Bay-Area-style startup mansion where startups work, collaborate and network, home of the famous OpenReaktor events and ReaktorX pre-acceleration program.

I occasionally mentor early stage startups at Google for Startups, The Founder Institute, Huge Thing, mspark and other accelerators.
