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
PostHog
- Extreme transparency — public handbook, open-source everything, radical autonomy
- Generous compensation with competitive pay, equity, and home office budget
- Small team means limited career progression paths
- Top-down decision-making can sometimes override team input
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.
PostHog
Radically transparent open-source culture with 2-3 person autonomous teams, no deadlines, and a public handbook — ideal if you're self-motivated, tough if you need structure.
