CV

I’m Klaus Breyer. With a lifetime in tech, a degree in Software Engineering, and a passion for innovation, I went from founding my first startup in 2010 to playing key roles as CTO/CTPO in many others.

I’ve anchored my beliefs in Shape Up, the next wave of agile.

I turn visionary business goals into concrete results, with focused expertise at the intersection of product and tech organization. It’s not merely about coding; it’s about crafting standout products that make a mark and drive business forward.

Startup strategy & product-market fit – turning ideas into impactful ventures.
Selling the tech vision – whether it’s to investors or stakeholders.
Prototyping & Crafting the first version of a product from scratch, if need be.
Assembling and Nurturing a Killer Team – Remote or in Berlin, transitioning from chaotic ad-hoc development to structured product delivery cadence.
Bringing product & engineering processes up to speed - fostering asynchronous collaboration.

Tech, product, business – that’s where I thrive.

For me it is not about code, it’s about weaving the tech fabric into the company’s culture.

For agencies, SME or fledgling startups - Teams that innovate and Projects that matter.

Start, Iterate, Fight Bullshit.

That is my Motto and I’ve penned down my thoughts in articles and shared them out loud at conferences. Whether it’s a page or a stage, I’m there.

That’s all.
