Michael Seibel Steps Down as Y Combinator Partner Emeritus

Michael Seibel is stepping back from his active role at Y Combinator (YC) after more than 12 years, transitioning to a Partner Emeritus position. Seibel's influence at YC has been profound, having served in various capacities including CEO, and he played a crucial role in mentoring startups and enhancing diversity within the founder community. His decision to step down follows a gradual reduction in his operational responsibilities, culminating with the completion of the Winter 2025 batch. In his new role, Seibel plans to continue supporting former mentees while pursuing interests in public service, specifically aimed at improving government operations. YC's CEO Garry Tan acknowledged Seibel's significant contributions to the organization, which has been pivotal in nurturing early-stage startups. As Seibel embarks on this new chapter, he leaves behind a legacy that will continue to influence YC's approach to startup support.
