Some quick searching says openai had a headcount of 3500 employees in 2024. It also had a valuation of $150billion. Another search says $150 billion companies tend to average 10000-50000 employees. So it does seem like they’re doing more with less. A different search says average company with $3 billion revenue has 5000-10000 employees. Either way OpenAI seems to be running leaner than average.
