Sarah Betensky '27
Classics & Political ScienceSarah Betensky is a senior at Brown University, from New York City, concentrating in Classics and Political Science. Her entrepreneurial journey began during her freshman fall semester, when she had the opportunity to pitch a venture idea to a panel of judges (Mayor Smiley, Chris Cocks, Jennifer Todd) as part of The Nelson Center’s Innovation Dojo startup incubator. Since then, she has taught and advised 80+ students developing their own startups as an Innovation Dojo mentor (2024-2025) and co-director (2025-2026). Leading Innovation Dojo has allowed her to connect with founders and investors across a wide range of industries, as well as introduce students to valuable resources and collaborators at early venture-building stages.
She's also gained hands-on entrepreneurial experience through interning at an early-stage food startup and a fashion brand, and through a strategy consulting internship at Ipsos Strategy3 — professional experience that's sharpened her skills in bottom-up research, pitch deck development, brand strategy, competitive analysis, and public speaking. Sarah is happy to advise on idea validation, bottom-up research, pitch deck construction, relationship-building, early-stage go-to-market questions, and any other questions around navigating the entrepreneurial process as a Brown student. Outside of entrepreneurship, she loves to travel and is very interested in the intersection between international affairs, cultural heritage, and business. -
