The deal with Pioneer Merger Corp. values Acorns at $2.2 billion, the companies said in a statement. The transaction also includes a $450 million PIPE, or a private investment in public equity.

Founded in 2014, Acorns offers an app with investing and banking products for relatively low monthly fees to more than 4 million subscribers. The firm said it now expects to jump to 10 million paying customers by 2025.

Chief Executive Officer Noah Kerner will continue in that role after the deal, which is expected to close in the second half of 2021. Citigroup Inc. served as an adviser to Pioneer as well as the exclusive placement agent on the PIPE. Moelis & Co. advised Acorns.

“Going public will help elevate our story, introduce many more people to the power of compounding and financial wellness, and bring financial literacy to the mainstream,” Kerner said in the statement.

Pioneer is led by Chairman Jonathan Christodoro and Co-Presidents Rick Gerson and Oscar Salazar. Christodoro is a member of the board of directors of companies including PayPal Holdings Inc., while Salazar is the co-founder of Uber Technologies Inc.
