Senior Data Scientist

Financial institutions process billions of transactions every day across cards, ACH, wires, and third party aggregators. But most of that data is difficult to use. Descriptions are inconsistent, merchant names don’t match, and categories vary by payment type.

Spade’s API takes these raw, messy transactions, and in <50 ms, returns clean, structured records linked to verified businesses in our proprietary database. Building on that foundation, our agent layer leverages this enriched data to automate insights and decision-making. Customers including Stripe, FIS, Bilt, Corpay, and Mercury use Spade to authorize more transactions, personalize experiences, power rewards programs, and more. We lead the market in merchant coverage, speed of enrichment, and data accuracy, enriching hundreds of billions of dollars in transaction volume every month.
