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.
Weaviate
Choose Weaviate if you want excellent remote culture with flat hierarchy and open-source mission — but expect startup growing pains.
