Yeeld builds credit-card surcharging infrastructure for merchants and platforms across the United States and Canada, and provides payments consulting and development services. The Yeeld Surcharging API is a real-time rules engine: a caller passes a transaction amount and payment-method details, and Yeeld returns the surcharge that jurisdictional law and Visa, Mastercard, American Express and Discover rules permit, or zero where surcharging is prohibited. Yeeld also ships a Stripe App Marketplace app for Stripe Checkout and Payment Links, and YeeldPay, a no-code branded hosted checkout. Founded by ex-Stripe staff and headquartered in Chicago, Illinois.
