Zuora

Zuora is a strong match for the Stripe Payment Platform concept, particularly in its core offering of subscription and recurring billing management. While it doesn't explicitly focus on general payment processing for all types of businesses like Stripe, it clearly handles payment processing within the context of subscriptions and usage-based models. It also provides robust developer APIs and SDKs, fraud prevention, and reporting capabilities. The website emphasizes its role as a 'monetization platform' for recurring revenue businesses, which aligns well with the concept's focus on economic infrastructure for online transactions, especially those involving subscriptions.
