Co-founder Greg Brockman is taking a more hands-on role to build a leadership team to surpass Anthropic in enterprise adoption, and has appointed Dali Rajic, former president and COO of Wiz, to replace Dresser. The departures also include heads of ethics, safety, and mission alignment, amid a broader reorganization of AI safety teams.", "body_md": "A wave of top OpenAI executives — including Sam Altman's top deputy, a longtime chief operating officer and the chief revenue officer — has left in the span of a month as the company retools its leadership ahead of an expected IPO.\nWhy it matters: Co-founder Greg Brockman is getting more involved across every level of the company to build out a leadership team he hopes will catapult OpenAI past Anthropic in enterprise adoption, according to a source familiar with the matter.\nZoom in: OpenAI's recent personnel changes are driven by strategy more than the revolving door that's come to define the broader AI talent exodus.\nOpenAI chief revenue officer Denise Dresser is leaving the company less than a year into the role.\nThe lab appointed Dali Rajic, most recently president and COO of Google-owned cybersecurity company Wiz, to replace her.\nHer exit comes the same week longtime OpenAI executive Brad Lightcap — the company's former COO — announced his departure, along with the head of ethics, head of safety and chief futurist.\nFidji Simo, the number two at the AI lab under CEO Sam Altman, left last month after taking a leave of absence for health reasons.\nBetween the lines: Brockman is \"a founder in founder mode,\" according to a source familiar, meeting with more customers and teams across the company than ever before.\nThe departures are viewed as a long-overdue clearing of underperforming leadership, another source says.\nBrockman told reporters, including Axios, at a July roundtable that he was \"very focused\" on \"the compute side and on the model execution side\" last year, but that he's now focused on the \"compute-powered economy.\"\nWhat they're saying: Brockman is publicly framing the departures as a change in corporate focus.\n\"Denise has led our revenue organization through a formative period for the business,\" Brockman said in a blog post about the personnel changes.\n\"The way we're deploying this technology is changing rapidly, and Dali will turn what we've learned into repeatable execution as we build out the full system to make AI broadly useful for people and businesses.\"\nZoom out: OpenAI's safety and alignment teams have also seen a spate of departures.\nThis week the Financial Times reported that the company's head of ethics, Chloé Bakalar, left after less than a year on the job. That follows the exits of head of safety systems, Johannes Heidecke, and chief futurist and former head of mission alignment Joshua Achiam.\nSandhini Agarwal, who previously led AI safety teams at the company, left in July.\nWired reports that the teams overseeing alignment for OpenAI's most powerful models are in the midst of a messy reorganization just as those models were found to escape their sandboxes and hack third-party systems.\nIf you have tips, DM Mady on Signal at madymills.21", "url": "https://wpnews.pro/news/openai-sheds-senior-execs-in-pre-ipo-refresh", "canonical_source": "https://www.machinebrief.com/news/openai-sheds-senior-execs-in-pre-ipo-refresh-1efn", "published_at": "2026-08-14 09:28:05+00:00", "updated_at": "2026-08-14 09:41:29.671078+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-policy", "ai-ethics", "ai-research"], "entities": ["OpenAI", "Sam Altman", "Greg Brockman", "Denise Dresser", "Brad Lightcap", "Fidji Simo", "Dali Rajic", "Anthropic"], "alternates": {"html": "https://wpnews.pro/news/openai-sheds-senior-execs-in-pre-ipo-refresh", "markdown": "https://wpnews.pro/news/openai-sheds-senior-execs-in-pre-ipo-refresh.md", "text": "https://wpnews.pro/news/openai-sheds-senior-execs-in-pre-ipo-refresh.txt", "jsonld": "https://wpnews.pro/news/openai-sheds-senior-execs-in-pre-ipo-refresh.jsonld"}}
