Pros & Cons
Celonis

- Great team culture with supportive colleagues and mentorship from leadership

Bottom Line
Celonis
Process mining market leader with decent equity and a learning culture, but at 3,800+ people expect real corporate layers — best for those who want large-enterprise scale over startup agility.
Poolside
Choose Poolside if you want cutting-edge code AI research on a remote-first flat team (ex-GitHub CTO leadership) — but expect early-stage ambiguity and comp that trails the larger AI labs.
