Btrs Holdings Inc
A maker of cloud software and payment tools that automates the business-to-business "order-to-cash" cycle — billing, invoicing, payments, and collections — for companies that sell to other businesses. Founded as Billtrust in 2001 by Flint Lane, who built the company in his basement after selling his earlier bill-payment firm Paytrust. The name blends "billing" and "trust," reflecting its mission to make B2B billing dependable. It operates under the trade name Billtrust.
