CTO Advisory for Founders

I help founders and leadership teams scale their business and technology without making costly, hard-to-reverse mistakes. As a CTO and board member, I scaled a regulated European fintech from early-stage startup to €1.4B in assets under management and 125,000+ clients.

My experience covers startup scaling strategy, CTO advisory for founders, aligning business goals with technology, and growing engineering teams without losing speed or ownership. I focus on practical decision-making around architecture, team structure, build vs buy choices, and timing — not on tools or coding.

Founders typically come to me when they need clarity, an external CTO perspective, or a sparring partner to think through scaling challenges and next steps with confidence.

Scaling Technology & Operations in Regulated Environments

I help founders and leadership teams scale technology and operations in regulated and complex environments without creating hidden risks. As a CTO and board member, I scaled a MiFID-regulated European fintech from early stage to €1.4B in assets under management and 125,000+ clients.

My focus is on operational scaling, automation, and identifying technical debt before it becomes a serious business problem. I work with teams that are growing fast and need their systems, processes, and internal tooling to keep up with regulatory, operational, and reliability requirements.

Founders come to me when things still work, but feel fragile — and they want to fix issues early rather than react to failures later.
