The USC Marshall Greif Incubator, established in 2010, is a program within the Lloyd Greif Center for Entrepreneurial Studies at the USC Marshall School of Business. It offers high-potential startups office space, mentoring, grant funding opportunities, and business/legal support services to guide founders from feasibility and MVP development to product-market fit, customer acquisition, and investment preparation.

The incubator operates on a cohort-driven model, accepting applications two to three times per year, and is open to current USC students, faculty, staff, and alumni. Over the past decade, it has supported numerous entrepreneurs, with graduates joining top accelerators, raising over $300 million in external funding and grants, and achieving acquisitions and other successes.
