Pros & Cons
Doctolib
- Mission-driven colleagues who genuinely care about improving healthcare access
- Strong growth opportunities with flexible remote policy and decent benefits
- Management can be heavy-handed — uses company principles as weapons against feedback
- French-centric culture makes it harder for non-French speakers to advance
Vast AI
- Front-row seat to the AI compute revolution — demand for GPU cloud is surging
- Strong compensation and generous equity stakes for a bootstrapped startup
- Processes are still being defined — expect ad hoc workflows
- Intense workload — the team explicitly values high output
Bottom Line
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.
Vast AI
Choose Vast AI if you want perfect Glassdoor scores and generous equity at a tiny GPU marketplace — but expect startup chaos.
