Brad Lightcap Exits OpenAI After 8 Years to Launch New Venture Amid Executive Shakeup

Brad Lightcap, OpenAI's longtime COO, is leaving to 'start something new'

Brad Lightcap, one of the longest serving executives at OpenAI, is leaving the powerful AI lab to "start something new." In an internal message which Lightcap shared online Tuesday, the outgoing executive told OpenAI staff that it was "bittersweet to share that I'll be moving on from OpenAI to start something new." Lightcap, who joined the company in 2018, spent four years as OpenAI's chief financial officer. He then ascended to chief operating officer, where he served from 2022 until earlier this year when, amidst a shakeup of executive roles, he transitioned to lead special projects at the company. Prior to OpenAI, Lightcap also worked with CEO Sam Altman at venture capital firm Y-Combinator. "I had the privilege of building the first versions of most of our operations and business teams - from Finance to Legal, People, CorpSec, GTM/Gov, Partnerships, and more," Lightcap wrote in his message Tuesday. "Among the most rewarding parts of this journey for me has been watching each of these teams mature under brilliant leaders." In his note, Lightcap also looked ahead and hinted at a future venture while giving scant details as to what it might be. "Over the last few months, I've been focused on the next horizon and what would stand in the way of mission success," Lightcap said. "I believe there are a few important new things the world will need to get right as we enter this next period. I'll have more to share soon, but I believe in OpenAI more than ever and am excited to help you all advance the mission from a different vantage point." As OpenAI preps for an IPO of industry-wide significance, the company has been undergoing a shakeup of top-level executives. In July, the company's No. 2 executive, Fidji Simo, who led AGI development, announced that she would be stepping down. Other executives from less central areas of the company -- including Bill Peebles, who formerly headed the company's now dead video generator Sora and Kevin Weil, the vice president of the company's Science vertical -- have also recently left the firm.

Another OpenAI executive takes off

Brad Lightcap, OpenAI's special projects lead and the company's former COO, announced his departure after an eight-year stint at the AI lab. In an internal memo he later posted to X, Lightcap told colleagues he'd be starting "something new." "Over the last few months, I've been focused on the next horizon and what would stand in the way of mission success," Lightcap wrote. "I believe there are a few important new things the world will need to get right as we enter this next period. I ... am excited to help you all advance the mission from a different vantage point." He added that he'd still be around for the next few weeks. Lightcap's role has changed a lot over the past year and a half. In March 2025, his role as COO expanded to include overseeing OpenAI's "business and day-to-day operations," heading up global deployment and "focusing on business strategy, key partnerships, infrastructure, and operational excellence to maximize the impact of our research." Then in January 2026, Lightcap took a step back from leading the company's enterprise push as far as product and engineering but stayed in charge of commercial functions. (Embattled AI executive Barret Zoph took over enterprise before departing about five months later.) In April, Lightcap officially stepped down from his COO role, transitioning into a new one leading the team's "special projects" and reporting to OpenAI CEO Sam Altman. Denise Dresser, the company's CRO, took over a significant portion of his former role. It's not the only high-profile departure from OpenAI's executive team in recent months: OpenAI's AGI chief, Fidji Simo, officially departed her role in July after a stint on medical leave, and in April, CMO Kate Rouch also stepped down for health reasons. There's also been a significant amount of company reorganizing and C-suite changes, with company president Greg Brockman taking control of the product side of things, and the company vowing to cut out "side quests" in favor of key revenue drivers as it prepares to go public over the coming year. "It always amazes me how quickly the world has adopted our tools and rallied behind our mission," Lightcap wrote. "I hope we will continue to earn their trust."

Longtime OpenAI executive Brad Lightcap leaves as shakeup at AI lab continues

Longtime OpenAI executive Brad Lightcap announced his departure on Tuesday, the latest in a series of recent leadership shakeups at the artificial intelligence company. Lightcap joined OpenAI in 2018 and held a number of senior leadership roles during his tenure, including a four-year stint as the company's operating chief. He served in that role until April, when he moved into a new position focused on "special projects." The company said at the time that Denise Dresser, OpenAI's chief revenue officer, would take over most of Lightcap's responsibilities. In a post on X on Tuesday, Lightcap said he is moving on from OpenAI to "start something new." "I feel incredibly fortunate to have spent most of the last decade pursuing our mission and building this company," Lightcap wrote. "Sitting here today, mission success feels within sight. It has been the honor of my life to help bring us to this point, and to do it alongside all of you." Lightcap's departure marks another key loss for OpenAI at a time when the company is trying to justify its $852 billion valuation and gear up for what's expected to be a monster IPO. Fidji Simo, who had been OpenAI's product and business chief, announced last month she was stepping down from her role at the company to focus on recovery after a "severe exacerbation of a chronic illness." Three other OpenAI execs announced their departures in April. They were Bill Peebles, who led OpenAI's defunct short-form video app Sora, Kevin Weil, the vice president of OpenAI for Science, and Srinivas Narayanan, tech chief of B2B Applications.

Brad Lightcap, a longtime OpenAI executive, said on Tuesday that he was leaving the company after eight years to start a new venture, the latest departure from the artificial intelligence start-up. Mr. Lightcap offered little detail about the new venture. He had joined OpenAI in 2018 and become its chief financial officer, and was appointed chief operating officer in 2022. He held that job until April, when he moved into a new role focused on "special projects." "It is bittersweet to share that I'll be moving on from OpenAI to start something new," he wrote in a note to employees that he also posted on social media. Mr. Lightcap's exit is the latest in a string of departures from OpenAI's senior ranks. Fidji Simo, who served as second in command to OpenAI's chief executive, Sam Altman, stepped down last month over health issues. Kate Rouch, the chief marketing officer, said she was stepping down in April to focus on cancer recovery. Kevin Weil, who oversaw science research after serving as chief product officer, left the company the same month. The turnover comes as OpenAI prepares to go public. In June, the San Francisco company filed confidentially for an initial public offering, but has leaned toward holding off on the event until next year. Mr. Lightcap and OpenAI did not immediately respond to requests for comment. (The New York Times sued OpenAI and Microsoft in 2023, claiming copyright infringement of news content related to A.I. systems. The two companies have denied those claims.)

OpenAI executive Brad Lightcap is leaving

Why it matters: It's the latest executive departure from the company and another example of an early employee leaving an AI lab to start their own thing. What they're saying: "It is bittersweet to share that I'll be moving on from OpenAI to start something new," Lightcap wrote in a message to employees that he posted on X. * He will stay at OpenAI for a few weeks and said he's "not going far" without offering much detail. * Lightcap reported directly to CEO Sam Altman, covering special projects after being moved out of the COO role in an in April when Thinking Machines Barret Zoph returned to OpenAI. * Zoph left OpenAI five months later. Zoom in: Lightcap is just the latest OpenAI executive to leave the firm. * Fidji Simo, OpenAI's number two executive, stepped down over health issues in July, though she has since joined an AI health startup. * OpenAI's head of ethics also left the company this week less than a year after joining. * The company's CMO also recently left to focus on her recovery from cancer. Zoom out: It comes amid a broader trend of longtime AI executives and even founders leaving their firms. * The latest high profile example is Jeff Dean, who left Google to start Discovery Loop. * Lilian Weng, a co-founder of Thinking Machines, left to rejoin OpenAI. The bottom line: The AI race's talent reshuffle continues.

Long-time OpenAI exec Brad Lightcap departs to 'start something new' | Fortune

Brad Lightcap, OpenAI's Chief Operating Officer and one of the most recognizable faces on its senior leadership team, is leaving the company to "start something new," he announced on Tuesday, representing the latest in a string of executive departures at the ChatGPT maker. Lightcap did not say what the new venture is, but said he's "not going far," and described it as involving "a few important new things the world will need to get right" as artificial intelligence becomes more powerful and capable. The departure comes as OpenAI is planning for an initial public offering that could value the San Francisco company at more than $1 trillion. It also comes as agentic AI models such as those made by OpenAI and Anthropic have come under increased scrutiny, following recent revelations that models from the two companies had managed to bypass safeguards and hacked into other systems. Lightcap joined OpenAI in 2018, when few people could have predicted that the company would become a household name after the release of ChatGPT in late 2022. He went on to create the "first versions" of several operations and business teams, he said, including finance, legal, HR, corporate security, go-to-market, and partnerships. "If you had told me then that we'd be where we are today, I wouldn't have believed you," Lightcap said in his announcement on X on Tuesday, which he also shared with the OpenAI team earlier today. "We grew from a small research lab to one of the most consequential companies of our time." Lightcap's mind has begun to wander to matters outside of OpenAI in the past few months, he said. He's been "focused on the next horizon," and solving issues he says might "stand in the way" of achieving OpenAI's vision of creating AGI, or artificial general intelligence, a still theoretical concept of AI that can match or surpass humans at most tasks. He did not elaborate, though it could relate to politics, infrastructure, public adoption, or any of the myriad challenges AI faces as the technology integrates into many aspects of society. "I believe there are a few important new things the world will need to get right as we enter this next period," Lightcap said. "I'll have more to share soon, but I believe in OpenAI more than ever and am excited to help you all advance the mission from a different vantage point." Lightcap plans to remain at the company for a few more weeks. It would be a major shock if Lightcap joins a competing AI lab, though time will tell. CEO Sam Altman and president Greg Brockman have not publicly commented on Lightcap's announcement as of this writing. Many OpenAI executives have stepped down this year It's the latest in a string of high-profile departures at OpenAI, and across the AI industry more widely, with Google DeepMind CEO Demis Hassabis stepping down this week as well. In April, three OpenAI executives announced their departures, including Bill Peebles, who led OpenAI's now-dead Sora video app, Kevin Weil, the vice president of OpenAI for Science, and Srinivas Narayanan, CTO of B2B applications. In June, Barret Zoph, the head of enterprise sales, left OpenAI for a second time. Zoph first joined in 2022, then left in late 2024 for a position at Thinking Machines Lab, a startup founded by former OpenAI CTO Mira Murati. He returned to OpenAI in early 2026, only to leave again five months later. In early July, Fidji Simo stepped down as OpenAI's CEO of Applications, followed by Johannes Heidecke, the head of safety. Heidecke's departure came just a few weeks before the company confirmed its AI agents had hacked Hugging Face during internal testing. Yesterday, The Financial Times reported that OpenAI's head of ethics, Chloé Bakalar, had quietly left the company after less than a year, with no public announcement. However, of all the departures, Lightcap's is the most significant given his long tenure and role crafting so much of OpenAI's foundational corporate structure. It is possible, if not probable, that Lightcap profited handsomely from the company's recent buyout of employee shares through an internal tender offer, as Bloomberg reported. Two former employees told Fortune that many people made out to the tune of $10 million through the buyouts, including those not in leadership positions. For someone like Lightcap who presumably accrued more shares at the highest appreciation possible, the payout would presumably be much larger.

Another OpenAI Exec Quits in Leadership Shake-Up as AI Giant Eyes IPO

OpenAI confidentially filed for a potential IPO in June but has not committed to going public. Longtime OpenAI executive Brad Lightcap announced Tuesday that he is leaving the AI developer after eight years to start a new venture. It's the latest among a string of departures at the AI behemoth, leaving observers to wonder what to make of the moves as OpenAI preps for an IPO. In a post on X, Lightcap said starting something new was "bittersweet," calling his years building the company the honor of his life. "Through it all, I'm proud of how we've maintained our focus on people," he wrote. "It always amazes me how quickly the world has adopted our tools and rallied behind our mission. I hope we will continue to earn their trust." Lightcap joined OpenAI in 2018 and spent four years as its chief operating officer. He helped build the company's finance, legal, personnel, corporate security, government relations, and partnership teams as it grew from a research lab into a major AI developer. "Sitting here today, mission success feels within sight," Lightcap wrote. "It has been the honor of my life to help bring us to this point." Lightcap's exit follows several leadership changes at OpenAI in 2026. Bill Peebles, Kevin Weil, and Srinivas Narayanan announced their departures in April, followed by product and business chief Fidji Simo, who stepped down in July to focus on recovering from a chronic illness. AI ethics lead Chloé Bakalar also left in July and reportedly has not been replaced. Bakalar's departure followed those of safety systems chief Johannes Heidecke and chief futurist Joshua Achiam that same month. The news comes as OpenAI prepares to enter the public markets. In June, OpenAI confidentially filed for a potential IPO but has not said when or if it plans to proceed. On Myriad, a prediction market developed by Decrypt's parent company Dastan, the market currently believes it's more likely rival company Anthropic IPOs before OpenAI at nearly 85% odds. Nevertheless, the expected public offering for Sam Altman's OpenAI has made its recent executive turnover a focus of speculation on social media. "It is just not that typical to have so many executives depart before their long awaited IPO," Partner at asset management firm ParaFi Jeff Park wrote on X. "Unless..." Whatever the reason, Lightcap expressed gratitude to his colleagues and said he would remain available to support them after his departure. "I am deeply grateful to have had the opportunity to work with all of you, and to so many of you for the support through the years," he wrote. "The old OpenAI meme that "the real AGI is the friends you made along the way" really rings true for me."

Who is Brad Lightcap? OpenAI veteran who helped turn ChatGPT into an AI giant quits; read his full resignation letter

In an unexpected move, Brad Lightcap, an instrumental executive at OpenAI, announced his departure to chase fresh opportunities. Since joining in 2018, he has been vital in shaping the company's enterprise business alongside Sam Altman. Despite leaving, Lightcap maintains a strong faith in OpenAI's vision and intends to assist the team as he ventures into new projects. Brad Lightcap, one of OpenAI's longest-serving senior executives and a key figure behind the company's rapid expansion into the enterprise market, has announced his departure from the artificial intelligence company. Lightcap, who joined OpenAI in 2018, said on Tuesday, August 11, that he is leaving the company to "start something new." His exit marks another high-profile departure from OpenAI as the ChatGPT maker continues to expand its business and AI operations. Who is Brad Lightcap?Lightcap has been part of OpenAI's leadership team since the company was still primarily known as an AI research organisation. He worked closely with CEO Sam Altman, with the two having previously crossed paths at technology accelerator Y Combinator. He served as OpenAI's chief operating officer for four years, overseeing a period in which the company transformed from a research-focused lab into one of the world's most prominent AI companies. Lightcap played a major role in building OpenAI's commercial operations. According to CNBC, over an 18-month period, he expanded the company's commercial team from around 50 employees to more than 700. The team covered areas including enterprise sales, developer relations, customer success and strategic corporate partnerships. How Brad Lightcap helped build OpenAI's enterprise businessThe expansion of OpenAI's commercial operations became increasingly important following the launch of GPT-4 and ChatGPT Enterprise. As businesses began adopting generative AI tools, OpenAI moved to turn ChatGPT's consumer popularity into a larger enterprise business, competing for corporate customers with AI rivals including Anthropic. Lightcap was closely involved in that commercial push and helped establish the teams and operations needed to support OpenAI's growing customer base. In April, he moved out of the COO role and took on a position focused on special strategic projects. Chief Revenue Officer Denise Dresser assumed most of his previous operational responsibilities. Why is Brad Lightcap leaving OpenAI?Lightcap did not provide a specific reason for his departure. In a message to OpenAI employees, he said he was leaving to "start something new" and indicated that he would share more about his next step in the future. He also made clear that his departure was not a break from OpenAI's mission. "I believe in OpenAI more than ever and am excited to help you all advance the mission from a different vantage point," Lightcap wrote in his message to employees. Lightcap said he would remain around for the next few weeks and would continue supporting the company from outside. Brad Lightcap's full resignation letter to OpenAI employeesIn his message, Lightcap reflected on his eight years at OpenAI, its transformation from a small research lab into a major technology company, and the teams he helped build. He recalled joining the company in 2018 after being introduced to Sam Altman, Greg Brockman and Ilya Sutskever and said he had been drawn to the challenge of working on artificial general intelligence. Lightcap also highlighted the growth of OpenAI's operations and business teams, including finance, legal, people operations, corporate security, go-to-market, government relations and partnerships. He described watching those teams mature under new leaders as one of the most rewarding parts of his time at the company. Reflecting on OpenAI's transformation, Lightcap wrote that the company had grown "from a small research lab to one of the most consequential companies of our time." He ended his message by thanking employees and referencing an old OpenAI joke: "the real AGI is the friends you made along the way." Lightcap said he would remain "a phone call away" for employees who needed him. Read Brad Lightcap's full resignation letter below: "Team, it is bittersweet to share that I'll be moving on from OpenAI to start something new. I feel incredibly fortunate to have spent most of the last decade pursuing our mission and building this company. Sitting here today, mission success feels within sight. It has been the honor of my life to help bring us to this point, and to do it alongside all of you. I joined OpenAI in 2018, eight years ago this month, because I wanted to work on something hard. @sama introduced me to @gdb and @ilyasut, who showed me a pitch deck suggesting that because models improve predictably with scale, AGI was not only possible but likely. If you had told me then that we'd be where we are today, I wouldn't have believed you. In the years that followed, I had the privilege of building the first versions of most of our operations and business teams - from Finance to Legal, People, CorpSec, GTM/Gov, Partnerships, and more. Among the most rewarding parts of this journey for me has been watching each of these teams mature under brilliant leaders. I am excited for the next decade in the hands of this incredibly capable team. At the same time, we grew from a small research lab to one of the most consequential companies of our time. I was reminded of that fact constantly - from serving our first user to our billionth, to the growing scale and ambition of our partnerships and the occasional curveball (the Blip, etc.). Through it all, I'm proud of how we've maintained our focus on people. It always amazes me how quickly the world has adopted our tools and rallied behind our mission. I hope we will continue to earn their trust. Over the last few months, I've been focused on the next horizon and what would stand in the way of mission success. I believe there are a few important new things the world will need to get right as we enter this next period. I'll have more to share soon, but I believe in OpenAI more than ever and am excited to help you all advance the mission from a different vantage point. I am deeply grateful to have had the opportunity to work with all of you, and to so many of you for the support through the years. The old OpenAI meme that "the real AGI is the friends you made along the way" really rings true for me. I will be around for the next few weeks. I am not going far and hope to continue to support you all however I can. I'll always be a phone call away if you need me."
