Founders & story · from FLEX’s own dossier

Flex (getflex.com) enables renters to pay rent on a flexible schedule that fits their personal finances, rather than being locked into a first-of-month due date. Note: multiple unrelated companies share the 'Flex' name (Flex Dental, Flexbase/flex.one, Flextronics, Flex Embedded, Flex Financial LLC, Flex Pay), and the evidence set is heavily contaminated with those namesakes; this analysis focuses on the rent-payment consumer fintech based in New York.
