Signifyd is a US commerce protection platform that replaces "should a human look at this" with a ship-or-not ship decision backed by a 100% financial guarantee, across 4 lines covering session intelligence, account integrity, purchase optimisation and returns assurance in 100+ countries.
Riskified, founded in Israel in 2013, sells chargeback liability shift rather than fraud tooling alone, letting merchants tune approval strategy to their risk tolerance while guaranteed fraud chargebacks are absorbed by the provider, alongside account takeover protection and checkout failure remediation.
