During the Black Friday to Cyber Monday weekend two years ago, about 8,000 people for the first time used Sezzle Inc.'s payment system when they shopped online.
A few weeks later, Sezzle executives mentioned that number to some bankers visiting their office in downtown Minneapolis. One of the bankers let out a giggle.
"It's kind of rude to do that," Charlie Youakim, co-founder and chief executive, said as he remembered the moment recently. "But I was thinking to myself, 'I don't think that person understands compound growth.' It's not as laughable where we're at now."
Last month, hundreds of thousands of people paid for $113 million in goods from retailers in the U.S. and Canada using Sezzle. Well over 2 million people have used Sezzle's payment system at least once this year, the company's data shows.
A shopper who chooses Sezzle instead of a credit card at checkout pays one-fourth of the purchase price immediately. The shopper pays the rest in three interest-free installments, with the first two weeks later and the last six weeks later. Sezzle makes money not from the shopper, but from the retailer, which pays a fee just as it would to a credit card firm.
By taking the old idea of paying for something over time and adapting it to e-commerce, Sezzle and alternative credit firms — AfterPay, Klarna, Affirm and QuadPay — have become a rising force. This year, the pandemic and economic downturn accelerated both the use of online shopping and installments for paying.
The firms are very small compared to banks and other credit card providers, but all now offer apps that take their services into the store shopping experience. The trade publication Pymnts.com reported that Sezzle's app was the fifth most-used in U.S. stores of the dozen or so alternative credit firms that it tracked in November.
From its start with three employees in 2017, Sezzle is on pace for revenue of around $45 million this year, growth that continued even as new competitors emerged. "A lot of doubts and concerns have been answered in 2020," Youakim said.
