OpenAI、今週2人目の幹部が退社へOpenAI is losing its second executive this week

OpenAI is confronting fresh questions about the stability of its senior ranks after a second high-profile executive announced plans to leave the company within a single week. Denise Dresser, OpenAI's chief revenue officer and the former chief executive of Slack, said she would depart in the "coming weeks" to "pursue other opportunities," according to a note to her team that she also posted on LinkedIn. For a company racing to convert its technological lead into durable revenue, the timing of the change is notable.

Dresser joined OpenAI in December as chief revenue officer, a role that typically oversees sales, partnerships, and the broader effort to turn products into recurring income. Her arrival came as OpenAI worked to scale its commercial operations, spanning consumer subscriptions to ChatGPT, enterprise deployments, and the developer-facing API business that many other companies build their own applications on top of. Before joining, she led Slack, the workplace messaging platform owned by Salesforce, a background that gave her deep experience in enterprise software and go-to-market execution.

Her departure comes in the same week that OpenAI saw another leadership change. Dali Rajic, who served as a president at the company, is the other executive tied to the recent turnover, making Dresser's exit the second within days. Details on both moves have been limited, and the announcements have been framed largely in the standard language of executives moving on to new endeavors.

The back-to-back news has drawn attention because continuity in commercial and operational leadership is often seen as important during a period of rapid growth. OpenAI has expanded dramatically since the launch of ChatGPT, and building out a leadership team capable of managing that scale has been a recurring theme. The company has also experienced notable turnover in its most senior positions over the past two years, including changes across its research, product, and safety leadership, as well as the widely reported boardroom turmoil in late 2023 that briefly saw CEO Sam Altman removed and then reinstated.

For an organization like OpenAI, the chief revenue officer is a pivotal position. The company competes with rivals including Google and Anthropic, all of which are investing heavily in both model development and the commercial infrastructure needed to sell AI tools to enterprises. Microsoft remains a major partner and investor, and much of OpenAI's technology is distributed through Microsoft's cloud and productivity products, which adds complexity to how the company manages its own direct sales relationships alongside those of a close ally.

Neither Dresser's note nor OpenAI's public comments, as reported, detailed the reasons behind the moves beyond the reference to pursuing other opportunities. It is not clear whether the two departures are related or coincidental, and the framing suggests they may reflect ordinary executive transitions rather than a single underlying cause. Still, losing two senior leaders in quick succession is likely to invite speculation about internal dynamics, particularly given the intense scrutiny the company attracts.

The changes also land at a moment when the broader AI sector is under pressure to demonstrate sustainable business models. Companies have spent enormous sums on computing power and talent, and investors are increasing
