Berlin, September 23, 2026. Fabian Tönnesmann has been appointed CEO of Turbine Kreuzberg. Effective immediately, he is responsible for strategy, business consulting, and sales, joining the company’s leadership team alongside founder Alexander Janthur. Together, they will shape the next chapter of the Berlin-based technology company. Tönnesmann’s appointment comes at a time when the relationship between consulting and software development is undergoing fundamental change.

Tönnesmann brings many years of experience in strategy and technology consulting, including work for clients such as Hapag-Lloyd, ABB, and ADAC. Most recently, he was Partner and Managing Director at Eraneos. Before that, he held a leadership position at Accenture Song.

“Artificial intelligence is accelerating software development and changing the point at which consulting needs to make an impact,” says Alexander Janthur, founder of Turbine Kreuzberg. “The bottleneck is no longer implementation. What matters is truly understanding our clients’ businesses and being able to assess what is worth developing. Fabian Tönnesmann combines entrepreneurial thinking, extensive consulting experience, and deep technological expertise. That makes him the right person to shape Turbine Kreuzberg’s next phase.”

From Intent to Code: Business and technology working hand in hand

Turbine Kreuzberg relies on integrated value teams: business strategy, product design, and software engineering work together from the initial business question through to live operation. Guided by the principle “From Intent to Code,” core business processes are translated directly into working software. AI accelerates and scales development, while people remain responsible for defining requirements, evaluating results, and making key decisions.

Fabian Tönnesmann, CEO of Turbine Kreuzberg, says: “We have reached a point where a business strategy can no longer simply be described, it has to be built. Every process step, every intention, and every decision becomes software. That is why strategy and engineering work together in the same team at Turbine Kreuzberg, with shared responsibility for the outcome. This is made possible by the technological depth we have built up over more than 25 years. I’m especially looking forward to showing what business and technology can achieve when they are brought together from the outset.”

André Wilke, Global Head of Revenue Management at Hapag-Lloyd, describes what this means from a business perspective: “Business and IT are no longer separate worlds at our company, they are becoming increasingly interconnected. AI has shortened the path from a requirement to testable software so significantly that concept phases without a working result are becoming difficult to justify. We therefore expect our partners to understand our business and develop the solution themselves, not describe one part and pass the other on.”
