WIND Mobility
Situation: A shared-mobility startup in turnaround mode: operations unstable, costs high, growth flat, and a European expansion in the wings that the operating setup couldn't support.
Steps: Ran a 25-person team across operations and marketing: built the KPI and tracking system, standardized processes and routes, trained the teams, rebuilt brand and app experience. Strengthened collaboration with the China-based tech and supply teams.
Result: 7x growth in rides and active users within 6 months, operating costs down 30% within the first 2 months, cost per conversion from €3.60 to below €1, and 5 more city launches across Spain, France and Austria.
BCG
Situation: BCG decided to overhaul how 15,000 employees worldwide communicate visually, the largest internal transformation in the firm's history. The hard part: getting a global organization of experts to change daily habits.
Steps: User research across regions, agile iteration of the toolkit, a phased rollout strategy, and sponsorship up to the Executive Committee. Recruited and trained 25 design coaches for regional hubs to carry the change locally.
Result: The first simultaneous global rollout in BCG's history, adopted across all offices by 15,000 people, with lasting effects on productivity and the quality of client work. Still in use today.
150 Minuten
Situation: Our D2C health platform had a working product and users who loved it, but customer acquisition costs the company couldn't sustain. The B2B opportunity was visible; the startup wasn't built for it.
Steps: Kept investors and team aligned through the change, restructured the team from 20 to 7, rebuilt the go-to-market for corporate customers with a 200+ enterprise pipeline, and closed the first DAX-listed customers.
Result: A working B2B motion in a company built for D2C. The first enterprise contracts came, but they came too late for a funding climate that had frozen long before. We then ran a structured, transparent wind-down: content assets sold, employees treated fairly, investors informed at every step.
