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
Mercury
- Strong talent density with smart, motivated teammates and genuine autonomy and ownership
- Great Place to Work certified — product-first mindset with meaningful scope for every engineer
- Still figuring out how to scale processes — expect some ambiguity and shifting priorities
- Work-life balance rated 3.8/5 — periods of higher intensity during rapid growth phases
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.
Mercury
Choose Mercury if you want product ownership, fast growth, and to build banking infrastructure for startups — but expect growing pains and occasionally intense workloads.
