Affirm 

Founded in 2012, Affirm is a market leader in the buy now, pay later space with around $36 billion in transaction volume in fiscal 2025. Affirm offers both zero-interest financing, which is merchant-subsidized, and interest-bearing loans, which function as personal loans that are approved on a per-transaction basis. Over 70% of Affirm's transaction volume comes from its interest-bearing loans, which also constitute the majority of its revenue. Affirm primarily operates in the United States, which accounted for more than 95% of its revenue in 2025, but it has also expanded to Canada and the United Kingdom.
