Pros & Cons
Adyen
- Smart, humble colleagues with high standards and a market-leading payments product
- Good work-life balance with trust-based culture, free lunch, and international team trips
- Below-market compensation (~20% less than peers) with poor stock options
- Middle management quality issues as company scaled — inexperienced managers and internal politics
Sierra
- Elite founders with proven track records
- Strong equity at $10B valuation
- In-person-first culture
- Competitive intensity may not suit everyone
Bottom Line
Adyen
Adyen's engineering culture is well-regarded in fintech — principled, WLB-conscious (4.1/5), and technically rigorous — but expect a methodical Amsterdam-centric culture rather than a high-growth startup vibe.
Sierra
Choose Sierra if you want elite founders (Bret Taylor, Clay Bavor) and strong equity at a $10B enterprise AI company — but it's in-person-first and the competitive intensity won't suit everyone.
