Flex is a consumer financial technology company that lets renters pay their monthly rent in smaller installments spread across the month, instead of a single lump sum on the due date, so payments better fit each person's pay schedule and cash flow. The company pays the landlord or property manager in full on the due date and collects from the renter over the month, positioning itself as a flexible-payments layer on top of the largest recurring expense most households carry. Founded in 2019 and headquartered in New York City, Flex operates a consumer mobile app and partners with property-management platforms; it is backed by Lightspeed Venture Partners and surfaced in the 500 Global portfolio. Flex publishes no public developer API, developer portal, or discovery surface today - this profile is a network lead.
