Pros & Cons
Granola
- Users absolutely love the product — everyone at Granola genuinely cares about quality
- Plenty of opportunities to work on things that make a real difference on a small team
- 5 days in office by default (with flexibility for life circumstances)
- Small team, so things can be busy — you'll wear many hats
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
Granola
Choose Granola if you want to work on one of the most loved AI products with a small, London-based, in-office team obsessed with craft — but note the 5-days-in-office policy is explicit and non-negotiable.
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.
