Pros & Cons
Celonis
- Strong learning and development opportunities with excellent internal mobility

- Frequent organizational changes and restructuring with poor communication from leadership

- Top-down decision-making can sometimes override team input
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.
PostHog
Radically transparent open-source culture with 2-3 person autonomous teams, no deadlines, and a public handbook — ideal if you're self-motivated, tough if you need structure.
