Want to double your team's productivity with best-in-class support? For a limited time I offer consulting projects.

Ground the work in real team data, implement the right changes, and monitor the uplift.
1. Establish baseline
Teams run on DoneThat so there is honest signal on how work actually happens, not slides and memory.
2. Grounded advice
What to change first, anchored in that baseline, not generic AI advice or slide-deck guesses.
3. Implement with teams
Hands-on work on high-leverage process and tooling changes people will actually adopt.
4. Monitor uplift
DoneThat stays in the loop afterwards so you can see whether productivity and AI uplift show up in practice.

2019 - 2024
“Christoph’s unique combination of technical skills and leadership ability allowed him to become the natural CTO for CarePay, building out our data science team, managing complex migrations, different financial climates, and our ISO 27001 certification, all with a disarming laugh.”
“Loved working with Christoph. He combines his drive to always question things with high agency and actual pragmatic solutions. He moved the full company from WhatsApp to Slack, drove AI tool adoption before the hype, and managed continuous roadmap delivery during pretty chaotic times.”
2016 - 2019
“Christoph was instrumental in shaping BCG’s AI strategy in the early days. He drafted articles on AI adoption in business, built the first AI use case library, gave internal and external trainings on AI, and facilitated AI adoption projects at clients”
2016
“Collaborating on projects can be a pain. Not with this German. Fast thinker, no bs, sits down and gets it done, all while having fun. We tried a few times to find a project to work on together again - one day!”
2012 - 2016
“Christoph was a joy to work with. He brought a combination of curiosity, agency, and positivity that isn’t easy to find. It’s a pity he didn’t stay in academia, but I can see that he is a better fit for the fast-paced environment of consulting and startups.”
2009 - 2012
“Christoph was great! Without much supervision he taught himself robotics, gaussian processes, and C++, built a simulation from scratch, applied the learnings on two separate humanoid robots, and got published in one of the most prestigious conferences. All in six months.”
