Our Company:

Sezzle is a cutting-edge fintech company whose mission is to financially empower young consumers.

To address these problems, Sezzle has built a payment platform that increases purchasing power for consumers by oering interest-free installment plans at online stores. This increase in purchasing power for consumers leads to increased sales and basket sizes for the thousands of eCommerce merchants that currently work with Sezzle.
