Karol is one of the best people I have worked with. I have followed his careers for over the past ten years now and I have watched him grow from someone deeply hands-on with the technical side into a leader with real strategic and people responsibility, without losing what made him great in the first place: there’s a real person behind every technical problem. Give him a messy customer issue and he will quickly turn it into a clear, thoughtful product decision. That combination is rare. I trust him completely, and his work speaks for itself.

Karol has a true “whatever it takes” mindset and a level of ownership I’ve rarely seen in my entire career -when he gives you his word, you can consider it done. I’ve seen him grow from CTO to CPTO brilliantly, combining extremely deep technical expertise with a rare ability to understand product and business challenges. If I were starting a company tomorrow or needed someone I truly trusted for advice, Karol would be at the very top of my list, 100%.
I had the pleasure of working closely with Karol on several fintech partnerships as Head of Partnerships. He brings a rare combination of strategic clarity and operational rigor, able to translate complex partnership requirements into product decisions the whole team could execute against with confidence. Karol was instrumental in driving these initiatives from concept to real, shipped outcomes, always deeply engaged and exacting in his standards. A CPTO who genuinely partners with the business side, not just supports it.
