CEO Zaid Rahman identifies his core market as "jumbo shrimps"—enterprises generating tens to hundreds of millions in revenue that remain underserved by traditional regional banks. While many fintechs isolate specific functions like accounting, Flex bundles private credit, business finance, and payment tools into a unified interface. The platform's integrated AI agent, Beacon AI, provides business owners with automated weekly financial health diagnostics.

With a current customer base reaching several thousand, the company reports a four-fold year-over-year growth trajectory at a nine-figure annualized revenue run rate. To support this scale, Rahman plans to increase the headcount from 110 to over 200 employees by the end of the year. Alongside the funding news, the company launched Flex Global, a service leveraging stablecoins to facilitate cross-border payments across 100 countries, allowing businesses to manage assets in 32 different currencies.
