Signifyd builds a commerce-protection platform for online retailers: machine-learning fraud decisions with a financial chargeback guarantee, plus return-abuse, policy-abuse and account-takeover protection, sitting on a commerce network spanning thousands of merchants. Founded in 2011 in San Jose and venture-backed, it acquired Keyri in late 2024 to deepen account-integrity protection. Its ads describe a workforce that is mostly remote, with teams gathering about once a year.
