What Kard does

Kard Financial, Inc., founded in 2015 and headquartered in New York, operates a rewards-as-a-service platform and self-described commerce media network that enables fintechs, banks, and merchants to embed card-linked offers and personalized cash-back rewards into their card products. The company's core product is a RESTful API (with SDKs in TypeScript, Java, Python, Go, and .NET) that ingests issuer transactions, matches them against available merchant offers via a multi-tiered algorithm with sub-minute notification delivery, and handles reconciliation, attribution, and user/merchant management. Kard has built first-party transaction data assets across 47M+ cardholders and 25K+ merchant locations, which feed a predictive AI engine for hyperpersonalized offer targeting; the platform is PCI DSS and SOC 2 Type 2 certified and integrates natively with Marqeta and Databricks.

Kard generates revenue primarily through performance-based merchant commissions on verified card-linked offer purchases, supplemented by platform/API access fees and revenue shares with card issuers. Its go-to-market is API-first and B2B2C, combining enterprise field sales to large banks and fintechs, a self-serve developer portal with sandbox onboarding, and white-label partner integrations with platforms such as BM Technologies, OnePay, and Grit Financial. The company reports network scale of 47M+ cardholders and 25K+ merchants, claims $10:1 topline ROAS for marketers, 40% more repeat purchases, and 15% re-engagement of previously inactive cardholders, and has raised a $23M Series A led by Tiger Global (2022) plus $15M in growth capital from Trinity Capital (October 2025) for a fully-remote team of approximately 50 employees.
