Dipti Desai
Dipti Desai is the co-founder and CEO of Crstl, a San Francisco startup rebuilding B2B commerce around the decades-old EDI standard that quietly governs how brands sell to retailers. A Virginia Tech electrical engineer and Uber data-platform veteran, she stumbled into the problem while volunteering to sell PPE online during the pandemic and discovering that the plumbing of wholesale was stuck in the 1980s. She has raised over $10 million from Target, Shopify Ventures, Cohen Circle, and Village Global to make EDI usable by people who are not developers.

The company runs AI-assisted, cohort-based programs for medical assistants, pharmacy techs, and other frontline roles, places graduates through a network of 8,000+ clinical partners, and was ranked the #1 EdTech company in the U.S. by TIME in 2025.
