Pros & Cons
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
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
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.
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.
