Everyone ignored this problem—until it became an opportunity. Alexander Rinke, co-founder of Celonis, turned a student project into a $13B+ process mining giant from Germany.

Born and raised in Berlin, he went on to build a software empire that has saved companies like Pfizer $300M.

This episode of HD in HD explores Alex’s path from student founder to CEO—and how he sees AI transforming the way companies run.

Alex and I also unpack:

• how 1,500 handwritten letters helped him land Siemens

• why AI’s next wave hinges on process overhaul

• how a $50K project outgrew his McKinsey dreams
