I build products that solve real problems, move fast from idea to impact, and invest in ambitious people at the earliest stages through CHventures. I bring multi-year experience in building, shipping, and scaling digital products across mobile, web, and AI, with products reaching more than 20 million users worldwide. I previously founded AVIMBU, where I built and delivered products end-to-end. Today, I focus on high-conviction opportunities and early ideas where technology can create real leverage.

Building and investing

Through CHventures, I work on new product ideas and invest selectively in early-stage people and companies. My interests are broad, with particular attention to robotics, aviation, health, and AI-enabled businesses.

Selective advisory and consulting

I work with a small number of selected companies where I can contribute meaningfully across product thinking, technical architecture, and execution. My background spans iOS, web, and AI-driven products, with a hands-on, founder-level approach.

Beyond work

Outside of work I enjoy staying active - running, gym training, golf, and skiing. Long walks with my dog help me reset, recharge, and think through new ideas.
