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
OpenAI
- Cutting-edge frontier AI research with world-class colleagues
- Elite compensation — top-tier TC and equity packages
- High-intensity environment — long hours and intense pace are the norm
- Internal politics and rapid org changes as the company scales
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.
OpenAI
High-intensity, mission-driven culture with world-class colleagues and top-tier comp — but expect long hours, rapid org changes, and internal politics as the company scales.
