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
Helsing
- Highest talent density of any tech company — world-class AI and engineering leadership
- Extremely important mission with rewarding impact and competitive salary
- Ridiculous expectations of work hours — high salaries do not mean constant overtime
- Some management not experienced enough to lead; lacking in performance feedback
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.
Helsing
Strong engineering culture with a clear mission — but that mission (AI for defense) is not for everyone. Research the ethics carefully before applying; those aligned will find unusually meaningful work.
