Pros & Cons
Mercor
- Massive impact at an AI company growing at breakneck speed
- Top-tier compensation with strong equity at $10B valuation
- Intense 9/9/6 work schedule — long hours are the norm
- Work-life balance is a real sacrifice at this stage
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
Mercor
Choose Mercor if you want outsized impact on AI-era hiring at a tiny, fast-moving team — but the 9/9/6 schedule is real, and work-life balance is genuinely sacrificed for speed.
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.
