OpenAI's Former COO Brad Lightcap Announces Departure to Start New Venture
Brad Lightcap, head of special projects and former Chief Operating Officer of OpenAI, has announced his upcoming departure, stating in an internal memo that he will "start new things."
Lightcap joined OpenAI in 2018, serving as Chief Financial Officer for four years before becoming COO in 2022, where he was responsible for building early operational and commercial teams in finance, legal, human resources, security, sales, and partnerships.
In early 2026, during a company executive reshuffle, he transitioned from the COO role to lead special projects, reporting directly to CEO Sam Altman, handling cross-company matters such as complex transactions and strategic investments, with COO responsibilities primarily taken over by Chief Revenue Officer Denise Dresser.
In his memo, Lightcap mentioned focusing on the necessary elements for success in the next phase over the past few months, expressing belief that the world needs to address some important new issues as it enters a new era, and he will share more details soon, stating his faith in OpenAI is stronger than ever.
He will remain for a few weeks for a transition period. Previously, he worked at Y Combinator and JPMorgan, and was one of the core operational leaders in OpenAI's transformation from a research institution to a commercial company.
The departure of key executives raises concerns about OpenAI's organizational stability and the pace of commercialization, as talent flows from large model companies to new startups or independent projects, putting short-term pressure on the original company and intensifying discussions around event-driven executive turnover.
This is another change following multiple rounds of executive adjustments at OpenAI recently.

Since joining OpenAI in 2018, Brad Lightcap has been responsible for operations and commercial system development, moving from CFO to COO and then to special projects, fully participating in the company's transition from research-oriented to scaled commercialization.
The capital path is reflected in his leadership of early team building and key partnerships, transitioning to a special projects role reporting directly to Altman, ultimately choosing to leave to start a new venture, motivated by a focus on the new capabilities and structures needed in the next phase of the industry.
Similar cases of executives leaving due to role adjustments or personal plans have been seen recently at OpenAI and other AI labs, currently in a phase of continuous restructuring of the core management team following rapid company expansion.
This essentially represents organizational restructuring, with mechanisms in place for accelerated commercialization and redefined responsibilities, as early core members choose to shift from internal execution to advancing missions from an external perspective.
