Behind OpenAI's exits and hires as it ramps up enterprise growth ahead of IPO

OpenAI has reshuffled its executive ranks once again, replacing its chief revenue officer just eight months after her appointment, as the ChatGPT maker races to strengthen its enterprise business ahead of a potential stock market debut.

The leadership change comes amid a broader wave of executive departures across the artificial intelligence industry, where competition for top talent has intensified even as frontier AI companies battle for customers, revenue growth and investor confidence.

The company announced Thursday that Denise Dresser, who joined OpenAI in December to help expand its enterprise business, will leave the company "for other opportunities."

She will be succeeded by Dali Rajic, the former president and chief operating officer of cybersecurity company Wiz, which was acquired by Google last year.

The transition comes as OpenAI continues to reorganize its leadership team while scaling its commercial operations and enterprise business, areas that have become increasingly important as the company competes with rivals including Anthropic and Google.

"Denise has led our revenue organization through a formative period for the business and has worked tirelessly to get the team to where it is today," OpenAI co-founder and President Greg Brockman said in a statement.

"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."

Executive departures at OpenAI gather pace

Dresser's exit adds to a growing list of high-profile leadership departures at OpenAI over the past year.

Earlier this week, Brad Lightcap, one of the company's earliest executives and former chief operating officer, announced his departure after eight years.

Lightcap joined OpenAI in 2018 and spent four years as chief financial officer before becoming chief operating officer in 2022.

Earlier this year, he transitioned to overseeing special projects following an executive restructuring.

Before OpenAI, he worked alongside Chief Executive Sam Altman at startup accelerator Y Combinator.

Several other senior leaders have also stepped away from the company in recent months.

Chief Marketing Officer Kate Rouch departed in April to focus on recovering from cancer, while Kevin Weil, who oversaw the company's science organization, also left that month.

In July, Fidji Simo, who played a central role in building OpenAI's commercial operations, stepped away from her full-time position for health reasons but continues to advise the company on a part-time basis.

The turnover has extended beyond the executive suite.

Bill Peebles, who previously led OpenAI's now-discontinued Sora video generation project, has also left the company.

The departures follow another wave of attrition in 2025, when OpenAI lost its chief people officer, communications chief, a senior researcher who later founded an AI science startup, and at least seven researchers recruited by Meta.

AI talent war reshapes the industry

While OpenAI has experienced significant executive turnover, industry observers note that such movement has become commonplace across the rapidly evolving artificial intelligence sector.

Competition for elite researchers and executives has intensified dramatically as technology companies race to develop increasingly capable foundation models.

In many cases, executives are moving between rival frontier AI laboratories rather than leaving the industry altogether.

OpenAI itself has also attracted high-profile hires over the past year.

Earlier this month, the company confirmed that Lilian Weng would return after leaving to co-found Mira Murati's Thinking Machines Lab.

Weng, who cited health reasons for stepping down from her startup role, previously served as OpenAI's Vice President of AI Safety Research.

The move was widely viewed as a significant gain for OpenAI given Weng's standing in AI safety research.

Google has also lost prominent researchers to competitors.

In June, Noam Shazeer left Google to join OpenAI, a hiring that many researchers viewed as one of the industry's biggest recruitment victories.

Shazeer co-authored the landmark 2017 paper introducing the transformer architecture that underpins modern generative AI systems, including ChatGPT.

That same month, Nobel Prize-winning researcher John Jumper departed Google for Anthropic.

Meanwhile, Dean Ball, who helped shape the Trump administration's early artificial intelligence policies, joined OpenAI in June to lead a new Strategic Futures team focused on frontier AI policy and internal governance.

Alphabet also recently announced a broader leadership overhaul of its AI division, with AI chief Demis Hassabis stepping back from his primary managerial responsibilities while several senior Gemini leaders, including veteran engineer Jeff Dean, also exited the company.

Enterprise growth becomes the priority

The latest management changes come as OpenAI increasingly shifts its focus from building cutting-edge AI models toward scaling its enterprise business and commercial infrastructure.

The company says its products now reach more than one billion weekly active users and two million business customers.

Despite that extraordinary growth, executives have acknowledged both publicly and privately that revenue has not yet met every internal target, according to TechCrunch.

This has increased pressure to strengthen the enterprise business before an IPO.

That challenge was one of Denise Dresser's primary responsibilities after joining OpenAI late last year.

According to Axios, Brockman has taken a much more active role across the organization as the company prepares for its next phase of growth.

A source familiar with the matter told the publication that Brockman is becoming increasingly involved with customers and internal teams as he seeks to build a leadership structure capable of helping OpenAI overtake Anthropic in enterprise adoption.

In May, Anthropic overtook OpenAI's most recent $852 billion valuation in March by announcing a $65 billion Series H financing round that valued the company at $965 billion.

"Brockman is 'a founder in founder mode,'" Axios quoted one source as saying, describing his increased engagement across the company.

Another source told the publication that the recent executive departures represent a long-overdue clearing of underperforming leadership rather than signs of instability.

Brockman has presented the leadership changes as part of OpenAI's evolving business priorities rather than a sign of instability.

"Denise has led our revenue organization through a formative period for the business," Brockman said in the blog post announcing the personnel changes.

"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."

IPO ambitions take center stage

The leadership changes come at a critical juncture for OpenAI as it prepares for what could become one of the biggest technology listings in history.

The company confidentially filed a draft registration statement with the US Securities and Exchange Commission on June 8, formally beginning the IPO process just one week after rival Anthropic submitted its own confidential filing.

While OpenAI has not announced a listing timeline, reports suggest the company is weighing whether to go public in late 2026 or delay its debut until 2027 in pursuit of an even higher valuation.

The New York Times reported in June that advisers presented executives with two options: proceed with an earlier listing at a lower valuation or wait until 2027 to target a valuation of $1 trillion.

According to the report, Chief Executive Sam Altman rejected any reduction in that valuation target as a "non-starter."

Even so, no IPO date has been confirmed, and the trillion-dollar valuation remains based on media reports citing unnamed sources rather than company guidance.

The decision carries financial implications.

OpenAI's projections reportedly show it expects to remain cash-flow negative until 2030, meaning a delayed listing could require another year of financing from private investors at its current valuation.

Revenue growth accelerates

Despite leadership turnover, OpenAI's business continues to expand at a rapid pace.

Bloomberg reported that the ChatGPT maker is on track to generate annualized revenue of more than $40 billion based on its current performance, roughly double its revenue run rate at the end of 2025.

People familiar with the matter told the publication that growth has accelerated in recent months, driven by increasing adoption of OpenAI's AI coding software alongside continued momentum in subscriptions, enterprise products and its emerging advertising business.

The company's consumer business also continues to grow.

According to an internal announcement cited by Bloomberg, Brockman told employees that OpenAI's annual revenue run rate increased by more than 20% month-over-month in July.

Chief Financial Officer Sarah Friar had previously said the company ended 2025 with annualized revenue exceeding $20 billion.

OpenAI also recently completed a secondary share sale worth roughly $7 billion, allowing current and former employees to sell shares at the company's $852 billion valuation.

The tender offer followed OpenAI's record-breaking $122 billion funding round completed in March and provides liquidity for employees ahead of a potential public listing.

Anthropic rivalry raises the stakes

OpenAI's preparations for public markets are unfolding alongside intensifying competition with Anthropic, whose own IPO ambitions have raised expectations across the AI sector.

According to the Financial Times, Anthropic investors expect the Claude developer to seek a valuation of at least $2 trillion in a potential October listing.

Investors also expect Anthropic's annualized revenue to reach between $100 billion and $120 billion by the end of 2026, underscoring the extraordinary growth projected for frontier AI companies.

If Anthropic proceeds first, it could become the first publicly traded pure-play frontier AI laboratory, potentially providing investors with the sector's first meaningful valuation benchmark.

Morningstar said that scenario would place additional pressure on OpenAI if it delays its own listing.

"It will arrive with something OpenAI cannot show: a profitable quarter. (Though Anthropic reportedly is warning that it may not repeat those numbers anytime soon.) Its first weeks of trading will be the closest thing to a verdict on valuations for the category," the research firm said.

Morningstar also pointed to differences in how the two companies report annualized revenue.

"One accounting question shapes all this. OpenAI is valued at about 34 times its sales rate, Anthropic at 20 times, but they count sales differently," the firm said.

"Anthropic includes revenue flowing through its cloud partners, while OpenAI counts only its share. Anthropic's figure would have to be roughly 40% too high for that gap to close. Its prospectus, public weeks before an October listing, will settle it."

For now, both companies remain privately held, and key details surrounding their IPOs—including valuation targets and listing dates—remain subject to change.

Still, OpenAI's latest executive reshuffle illustrates the balancing act facing the company as it simultaneously scales its enterprise business, manages leadership transitions, competes aggressively for AI talent, and prepares for a public market debut that could redefine investor expectations for the artificial intelligence industry.
