About Wholesail

Wholesail is an early stage startup that builds software to connect wholesalers and their buyers by automating and digitizing invoicing and payment in the $5 trillion wholesale trade industry. The company’s first product is an electronic invoicing and payment portal for wholesale sellers, which allows them to get paid faster and decrease losses. For buyers, Wholesail automates the accounts payable & expense management process to save them time and money. Wholesail’s initial industry focus is to build a network effect driven payment business in the highly fragmented $1 trillion US food distribution market, in which invoicing and payment is nearly entirely paper-driven today. The platform has gained great traction with early customers since its launch in mid-2019, with over 25% month-over-month growth in Gross Transaction Volume (GTV), and has a significant customer pipeline that’s gated on new feature development.

Wholesail was founded by a team of successful serial entrepreneurs whose prior startups were acquired by OpenTable and who worked together there as product managers, engineers and designers. The company is well funded with backing from a half dozen venture capital firms and 20+ angel investors with backgrounds in FinTech, Payments, SMB Marketplaces, food distribution and restaurants; including early executives and team members from Stripe, Square, Dropbox, Yelp, OpenTable and Everlane.
