Affirm is an American consumer lending company founded in San Francisco in 2012 that offers instalment loans at the point of sale, an approach usually described as buy now pay later. Unlike revolving credit it underwrites each purchase individually, discloses total cost up front and does not charge late fees, earning revenue from merchant fees on interest-free plans and from interest on longer-term loans. The company is listed on Nasdaq, partners with large retailers and marketplaces including Amazon and Shopify, and also issues a debit card that lets shoppers split purchases after the fact.

Valsoft is a Canadian company founded in 2015 that acquires and permanently holds vertical market software businesses rather than reselling them. It buys established, often founder-owned products serving narrow industries such as transport, hospitality, insurance, healthcare and utilities, then keeps them operating under their own brands with centralised support for finance, hiring and best practice. Headquartered in Montreal, it has completed well over a hundred acquisitions and operates on the model that a small software business serving an unglamorous industry can be extremely durable if it is never asked to grow beyond its market.
