Michael Seibel is stepping down from Y Combinator
Michael Seibel transitions to 'partner emeritus' at Y Combinator.

Michael Seibel recently revealed on X that he is transitioning to a 'partner emeritus' position at Y Combinator, an accelerator known for nurturing startups, after more than a decade of tenure. Y Combinator's CEO Garry Tan confirmed this change through a blog post, recognizing Seibel's substantial impact on the organization. Seibel's journey at Y Combinator began as a founder when he participated in the program twice, with the first venture being Justin.TV, a streaming startup, followed by Socialcam, another streaming application. Over the years, he took on several important roles within the company, including group partner, managing director, and eventually the CEO of Y Combinator's accelerator program.
Seibel's move to a less operational role had been hinted at in the past. In a past blog post for Y Combinator, he mentioned planning to 'hand over my leadership responsibilities,' which took effect after the accelerator's winter batch completed their program. This transition is significant considering Seibel's contributions spanning twelve years, a long period in any professional's career. It also coincides with Garry Tan's appointment as President and CEO in 2022, which reportedly led to surprise within the ranks, as Tan was involved with a separate venture fund, and many anticipated Seibel was next in line for the top role.
Michael Seibel has expressed his intent to take some time off during the summer before venturing into a new direction that rekindles his early passion—helping governments serve their citizens better. His announcement noted the passion he harbored for governmental engagements during his youth, highlighting a desire to reenter this arena. Seibel has shared his gratitude for Y Combinator founders Paul Graham and Jessica Livingston, citing that their influence has been transformative in his life.
Despite his departure from an active role, Seibel remains a figure of importance as Y Combinator prepares for its spring batch of startups which run from April through June. His future endeavors, especially his interest in governmental work, remain an intriguing development for those tracking his career trajectory. As the new batch of founders embarks on their journey with Y Combinator, Seibel's legacy as a pivotal part of the organization's history remains evident.
Instances like Seibel's transition reflect broader trends in the startup world and the continuous evolution of leadership within Silicon Valley's accelerators and venture capital ecosystems. The move not only marks the end of a significant chapter but also the beginning of potential new ventures in Seibel's professional life, bridging the private sector's innovative pace with public service aspirations.
