Our take
More and more people are looking to "Buy Now Pay Later" (BNPL) solutions to increase their purchasing power. Sezzle is one of a raft of companies offering interest-free payments solutions.
Sezzle was launched with the intention of giving ordinary people more financial agency. The platform offers consumers rapid approval decisions, and loans do not affect their credit score. What's more, users can opt-in to an innovative credit building service. Sezzle has further consolidated its market position by partnering with other companies, including customer service platform Klaviyo.
The prevalence of BNPL solutions has increased hugely in recent years, and Sezzle's main challenge will be competing with rival providers, including Klarna and PayPal. Post IPO, Sezzle experienced a market contraction in 2025 after questions were raised over its business model's sustainability, so it'll be interesting to see how the company responds and continues its growth.
