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
Together AI
- Open-source AI infrastructure — real mission alignment, not just marketing
- Small team with outsized research output; your work has direct impact
- Early-stage means wearing many hats constantly — not for specialists
- Limited career ladder; growth paths are still being defined
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.
Together AI
Choose Together AI if you want real open-source mission with outsized research output — but expect to wear many hats.
