What do we do? Paddle offers SaaS companies a completely different approach to their payments infrastructure. Instead of assembling and maintaining a complex stack of payments-related apps and services, we act as a Merchant of Record for our customers. That means we remove 100% of the pain of payments fragmentation. It’s faster, safer, cheaper, and—above all—better. We’re backed by investors including KKR, FTV Capital, Kindred, Notion, and 83North, and we serve over 6,000 software sellers in 245 territories worldwide. The role Selling online as a software business is a complex process and many components need to work seamlessly to capture revenue and deliver this to sellers. Paddle manages payments and billing, with a best-in-class developer-first approach, so that we can take this burden from our customers. Paddle is a financially-critical system used by a global customer base, processing hundreds of millions of dollars per month, so there is no shortage of interesting challenges.
