Stripe is payments and financial infrastructure for internet businesses. The core is Payments — online and in person, across 135+ currencies and payment methods — with Billing on top for subscriptions, usage-based pricing, and invoicing, and Connect for marketplaces and platforms that need to pay out to third parties. Around that sit Radar for fraud detection, Tax and Identity for compliance, Issuing for card programs, Payouts for global money movement, and Sigma and Data Pipeline for reporting.
Pricing is per transaction with no subscription. Stripe processed US$1.9 trillion in payments in 2025, reports 99.999% historical uptime and 500M+ API requests a day, and is used by Amazon, Shopify, Figma, Instacart, Uber, and Ford, along with 88% of the Forbes AI 50.
