Pros & Cons
Cognition
- Elite engineering team with strong equity

- High-intensity startup pace
- In-person SF expectations
Doctolib

Bottom Line
Cognition
Choose Cognition if you want world-class AI agent research (makers of Devin) with strong equity upside — but expect top-tier intensity and mandatory in-person in San Francisco.
Doctolib
Genuine social mission (digitizing healthcare access for millions) with a fast-shipping culture, but at 3,500 people reviews cite organizational change fatigue and management inconsistency.
