Pros & Cons
OpenAI
- Cutting-edge frontier AI research with world-class colleagues
- Elite compensation — top-tier TC and equity packages
- High-intensity environment — long hours and intense pace are the norm
- Internal politics and rapid org changes as the company scales
Supabase
- Truly open-source DNA — build products millions of developers use daily
- No-hierarchy remote culture with extreme autonomy and generous allowances
- Intense workload — more work than a single person can reasonably manage
- Work-life balance rated 3.0/5 — fast shipping pace can be relentless
Bottom Line
OpenAI
High-intensity, mission-driven culture with world-class colleagues and top-tier comp — but expect long hours, rapid org changes, and internal politics as the company scales.
Supabase
Egoless, fully remote culture with just one meeting per week and extreme autonomy — but the relentless shipping pace means work-life balance takes a hit.
