OpenAI's executive shake-up continues.

The company announced Thursday that it is replacing its chief revenue officer, Denise Dresser, after only eight months in the role.

Dali Rajic, formerly the chief operating officer of Wiz, is taking over the role with the monumental task of preparing OpenAI for its initial public offering, expected next year.

Dresser's departure joins a wave of change inside OpenAI's upper ranks.

On Tuesday, former chief operating officer Brad Lightcap said he'd be leaving the company — Dresser had been given parts of Lightcap's former remit as recently as April.

In July, OpenAI lost Johannes Heidecke, its head of safety systems, and Joshua Achiam, its chief futurist.

Fidji Simo, its CEO of applications, moved into an advisory role due to health reasons.

The dramatic upheaval comes at a crucial juncture for OpenAI.

This year, its rivalry with AI lab Anthropic reached a fever pitch, with the companies battling for market share and talent as they speed toward IPOs.

OpenAI is trying to parlay its billion users into a sustainable business, scrambling to build data centers and win customers as its core technology evolves.
