About the Company

Spade

Real-time transaction enrichment API for payments

Spade provides real-time transaction enrichment via an API that maps raw card transaction data to verified merchant identities, including granular category and geolocation details. The process starts when a client (such as a card issuer, neobank, or fraud platform) sends transaction data to Spade’s API; the system then matches the data to a real merchant identity, enriches it with additional attributes, and returns the enhanced transaction record to the client’s platform in under 50 milliseconds, enabling faster and more informed payment decisions during authorization. Spade serves fintechs and card ecosystems (examples include Ramp, Sardine, Unit, and Mercury) and differentiates itself through speed, real-time accuracy, and a security-conscious approach (SOC 2 certified and does not handle PII). The company's goal is to help clients improve authorization rates, strengthen fraud detection, and enable more capable card products by providing high-quality merchant data.
