The largest previous employers in OpenAI’s visible technical staff are Google, Meta, and Microsoft. Google accounts for 702 people (23%), Meta for 573 (19%), and Microsoft for 344 (11%). Apple is 240 and Amazon is 230. Read these as prior-employer counts inside the technical-staff map, not as a claim that OpenAI only hires from labs. They are not additive with the three-lab source mix, which uses a different company-wide profile cut.

Scope and limits
- Public profiles may contain update lags, self-presentation bias, and inconsistent titles.
- Figures are a visible sample for relative comparison. They are not official headcount and are not used to estimate a global workforce.
- Do not add these prior-employer counts to the three-lab source shares. That map uses a different profile cut.

FAQ
Is this only lab-to-lab hiring?
No. The largest named prior employers here are Google, Meta, and Microsoft.
Why do Apple and Amazon have no share?
The published catalog states Apple 240 and Amazon 230 as counts. This page does not invent a percentage for them.
Can I add this table to the 51.7% three-lab source share?
No. Enterprise SaaS plus Big Tech at 51.7% is a different map and a different cut.
Is 702 official headcount?
No. It is a visible prior-employer count inside the technical-staff sample.
