Simo, already a board member at OpenAI, will transition out of Instacart over the next few months and join the AI company full-time as Application CEO.

The hiring of the Instacart exec indicates that OpenAI's roadmap will involve more structured, productized offerings rather than just API access.

Simo will reportedly concentrate on scaling the company’s ‘traditional’ functions. The woman behind Instacart’s successful IPO, Fidji Simo, is joining OpenAI’s C-suite.
