01 — About

I'm a YC founder and ex-VC investor with an engineering background. I started my career as an electrical & electronics engineer at Gate Elektronik before co-founding LaserX, where we set out to build optical payloads and laser communication technology for nano/micro-satellites. I then spent two years as an Investment Associate at ACT Venture Partners, investing in early-stage European tech startups, before jumping back into building. I co-founded FashionI, bringing an algorithmic feed-based experience to e-commerce, and then SenpAI.GG (YC S21), a gaming coach for the 1.4 billion PC gamers worldwide, which I led as Co-founder & CEO for nearly five years. Today I'm a YC Alumni Partner at Founder Factor, an investment syndicate of YC alumni dedicated to backing the top 5% of YC startups. Across engineering, venture capital, and founding companies, I've built a career at the intersection of deep technology and product-driven entrepreneurship.

02 — How I Help
01

Founder Insight

I've built and led multiple startups from zero to product, including a YC S21 company, so I can share hard-won lessons on building, pivoting, and scaling.

Investor Perspective

Having sat on both sides of the table as a VC at ACT Venture Partners and now as a YC Alumni Partner at Founder Factor, I can help evaluate and back promising early-stage startups.
