Pros & Cons
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
Pylon
- YC + a16z backed with strong product-market fit in B2B customer support
- Small team with outsized ownership — every engineer directly shapes the product
- Polarized reviews — aggressive culture reported by some employees
- Very early-stage with minimal processes — only 4 Glassdoor reviews
Bottom Line
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.
Pylon
Small YC + a16z-backed team with strong product-market fit in B2B support — but polarized Glassdoor reviews flag an aggressive culture and minimal processes.
