Jahaan Ansari

Jahaan Ansari is the co-founder and CEO of Gainful, a New York-based personalized nutrition company that builds custom protein and supplement formulas around each customer. A UC Berkeley chemical engineering and computer science graduate, he wrote the algorithm that matches a person's body and goals to a unique blend, turning a college dorm-kitchen experiment that filled its first 50 orders by hand into a Forbes 30 Under 30, Y Combinator-backed brand sold at Target. He raised more than $17M with high-school-best-friend-turned-co-founder Eric Wu, and in 2024 took an unexpected detour onto ABC's The Bachelorette.
