Poseidon Fellows

UCSD Entrepreneurship Fellowship Application

📅 Application Deadline: March 22, 2026 at 11:59 PM · Spring Quarter 2026

About the Program

Poseidon Fellows is UC San Diego's premier entrepreneurship fellowship for builders, dreamers, and founders across all levels of study — undergraduate, graduate, and PhD. Modeled after world-class programs like the Mayfield Fellows at Stanford, we believe the best founders aren't made in classrooms — they're forged through mentorship, community, and real-world exposure.

Over the course of the program, Fellows receive access to founder mentors, investor office hours, a curated curriculum on company-building, and a tight-knit cohort of peers who share your drive to create something from nothing. Whether you have a company already or just a restless sense that something in the world needs to change — you belong here.

Each session is 90 minutes in the evening — 45 minutes of lecture followed by 45 minutes with a guest speaker and open Q&A (founders, executives, and investors). Attendance at all sessions is mandatory, so please make sure these dates work for you before applying.
