Companies that use Sardine

Source: Analysis of Linkedin bios of 4 companies that use Sardine

I noticed that Sardine's customers are digital-first marketplaces and platforms handling high-volume transactions in industries prone to fraud risk. They're not traditional e-commerce stores. Instead, they facilitate peer-to-peer exchanges, resale markets, digital goods, and event ticketing where verifying both buyers and sellers is critical. Whop processes nearly $1B in payments for digital products sold "guerrilla style" across social media. StockX runs a bid-ask marketplace for collectibles. SeatGeek operates a mobile ticketing marketplace. These are environments where fraud can enter from multiple sides of each transaction.

These companies span from growth stage to mature scaling businesses. Whop is Series A with 341 employees and rapidly growing transaction volume. SeatGeek and StockX are both Series E companies with 782 and 1,479 employees respectively, suggesting they're past product-market fit and scaling operations. The funding rounds and employee counts indicate companies managing serious transaction volumes where fraud prevention directly impacts unit economics.
