Interim, Crisis & Change Leadership · Tech & Product

I get your tech org back on track.

Delivery that's late, buggy, harder than it should be. A leadership team you've lost confidence in, or a CTO who's already gone. A critical project, or a deal, on the line. Underneath it's usually priorities, structure, or people, not what everyone's pointing at. I find what's actually broken and fix it, as interim lead, crisis lead, or advisor. On AI, I separate what's real from the hype. And if I'm not the right person for it, I'll tell you up front.

How I help

When it's on fire

Interim & Crisis Leadership

I step in as interim or crisis lead, take ownership, and stabilize the organization. Then I find and onboard the permanent leader to replace me, so the handover is clean, not a cliff.

Around the deal

M&A, Due Diligence & Post-Merger

I de-risk it: technical and organizational due diligence from the buyer or seller side, and post-merger integration that actually brings teams and systems together instead of letting them drift apart.

When leadership is in flux

Leadership Transitions & Realignment

I give you an honest read of the people and the structure, help you make the hard calls, restructure where the org design is the real problem, find the right people inside and out, and realign everyone on common goals.

As AI reshapes the work

AI & the Operating Model

AI is changing how tech and product orgs work: delivery, product discovery, how teams are sized and composed. The right answer is different for every company, and most of the advice out there is noise. I help you cut through it and find the model that fits your company, with people, not just tools, in mind.

“I've known Thomas for over 13 years through multiple ventures. His ability to bring order to complexity while maintaining strategic vision is remarkable. At Käuferportal, he transformed our tech organization from a small team into a powerhouse that enabled rapid growth and successful exit. When starting Valyria, he was my first choice as CTO and co-founder. Thomas combines deep business understanding with technical excellence, but what truly sets him apart is his calm, intelligent approach to complex challenges. His thoughtful nature and loyalty make him an exceptional partner through both tough times and success.”

“Thomas is one of the most detail-oriented people I know. At Honeypot, he led our complicated due diligence process during our acquisition. He led teams across the company, from IT to ops to complete the task. We couldn't have done it without him. If you are looking for a leader to bring structure to chaos, there is no better man than Thomas.”
