Pros & Cons
Baseten
- Cutting-edge ML inference infrastructure — deploying models at scale for real production customers
- Small team means high ownership and direct impact on product direction and company strategy
- Limited resources compared to larger competitors — can feel stretched thin on multiple fronts
- Fast-moving product roadmap means priorities shift frequently as the market evolves
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
Bottom Line
Baseten
Choose Baseten if you want high ownership building ML inference infrastructure at an early-stage startup — but expect startup intensity and shifting priorities.
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.
