Dill is a San Francisco fintech, founded in 2022 and backed by Y Combinator (W23), that helps construction wholesalers, distributors, and suppliers get paid faster. Its software digitizes the paper-heavy back office of the building-materials trade - online credit applications, accounts-receivable automation, white-labeled payment portals, and lien-rights tracking - and plugs into distribution ERPs like Epicor Prophet 21 and Eclipse. The pitch is simple: suppliers spend less time chasing invoices and more time selling.
Catherine Jiang is the founder and CEO of Dill, a Y Combinator-backed (W23) software company that helps construction suppliers automate accounts receivable, online payments, credit applications, and lien rights management to get paid faster. A second-time founder, she previously co-founded SiteTrace (acquired by BuildCentrix) and was a product manager at Yelp. She holds a B.S. in Symbolic Systems from Stanford. Dill launched in 2023 serving foodservice distributors and later refocused on the construction supply chain, where late payments and paper-based invoicing choke cash flow.
