Philipp John
Applied AI Engineer

Currently CTO at Cohaga AG in St. Gallen, where I lead a 4 FTE engineering team and work on identifying and implementing high-value AI use cases — most recently a production multi-agent system that replaced a 10+ FTE manual workflow and scaled data coverage 14x.
I hold an MSc in Computer Science from HSG (5.5/6.0), with an accepted publication at ACM DIS 2026.
Earlier practical experience in startups, consulting, and product management across pharma, automotive, and healthcare.
I've been building outside work since high school — most notably Basissatz, an e-learning platform that reached 500,000+ German students, plus Warwick Hyperloop, Pypeline.io, and a steady stream of smaller side projects.
