Documented cause
InAuth built a device identity and mobile authentication platform for financial institutions, processing billions of authentication events. Founded in 2012, the company attracted strong banking clients and raised significant Series A and B funding. However, as American Express acquired InAuth in 2017 for an undisclosed sum — reportedly under $200M — the independent platform effectively ceased to exist as a market entity. Post-acquisition, InAuth's technology was absorbed into Amex's internal fraud stack and was not offered as a standalone product to non-Amex clients, destroying the independent identity platform that had been built.
Lesson
“Strategic acquirers often buy identity platforms to eliminate competition, not to continue them as businesses.”
