Top SchoolThomas Handorf is a data and analytics leader, CEO of Berlin-based consultancy 9 friendly white rabbits, and a 14-year veteran of helping startups and established firms turn digital data into actionable strategy.

He also maintains open-source front-end work (layerJS) and has a scientific background in computational biology and large-scale Boolean network modeling, which informs his rigorous, model-driven approach to complex data problems. A former founder of Webpgr and participant in German Accelerator, he blends entrepreneurial product instincts with deep technical craft and an appetite for shipping polished, testable UIs. Outside client work he still codes and contributes to open-source testing and UI tooling, signaling a leader who remains hands-on.
