Investment to accelerate ProsperStack's mission to make it easy for subscription-based brands to prosper by automating and enhancing the customer retention experience.

ProsperStack, a leader in cancellation flow software boasting the ability to reduce subscriber churn by up to 30%, announced today that they’ve raised a $2 million Seed round, led by Sandalphon Capital. This investment brings ProsperStack’s total funding to date to $2.35 million, driving an impressive growth trajectory for the team of subscription industry experts.

“This raise is a result of the hard work the team has put in the past 12 months,” said Tony Sternberg, CEO & co-founder of ProsperStack. “ProsperStack is as much about helping our clients with retention as it is enabling them to create amazing offboarding experiences that their customers will love. We can’t wait to use these funds to scale our marketing, customer success, development and sales operations during our next phase of growth.

Thanks to their comprehensive suite of low-code tools optimizing self-service cancellation flows for customers in SaaS, newspaper, digital media, publishing, marketing, advertising, IT & telecommunications industries, ProsperStack’s number of subscribers is constantly increasing. Notable customers include Hootsuite, Roll20, SwingU, and Soundstripe.

“We’re excited about the strong product and value proposition, and impressive list of customers the team has already been able to achieve with only modest funding,” said Jonathan Ellis, General Partner of Sandalphon Capital. “Now they can accelerate their product vision and scale to help even more customers.”

Other participating investors included Homegrown Capital, Jason Calacanis’ LAUNCH fund, Groove Capital and Gopher Angels.
