10,000+ merchants including Walmart-owned Jet, Under Armour, Puma and Lenovo, with over a decade of operating history.
$205M Series E at a $1.34B valuation, roughly 3.4x growth in valuation since its 2018 Series D.

E-commerce fraud protection is a durable need tied to continued growth in online commerce.
Why CISOs Should Care
A CISO or e-commerce risk leader would use Signifyd for its financial guarantee model -- the vendor covers approved chargeback losses directly -- shifting fraud liability off the merchant rather than just scoring transactions.
What Makes It Different
Signifyd differentiates by financially guaranteeing its fraud decisions, covering chargeback losses on approved orders, which aligns its incentives directly with prevention accuracy in a way pure scoring vendors don't.
