Flex raises $70M to expand stablecoin business banking as corporate demand surges

Flex raised $70 million to expand its stablecoin-focused business banking platform, joining a wave of companies building corporate payment infrastructure on digital dollar rails.

"The funding will accelerate development of payment tools that let businesses hold, send, and receive stablecoins alongside fiat currency," a person familiar with the company's plans said. Flex, which operates a business banking platform centered on stablecoin technology, announced the round on July 14.

The funding comes as stablecoin adoption expands beyond trading into enterprise treasury and payment operations. Total stablecoin market capitalization stood at $312.3 billion, up 21.5 percent from $257.1 billion a year earlier, according to DefiLlama data. Bitso Business reported stablecoin transaction volumes rose 81 percent year over year in the first half of 2026, with more than 60 percent of new business clients being financial institutions including banks and licensed payment providers. A Paybis survey found that 22.5 percent of businesses already use stablecoins for international payments or plan to within the next 12 months, while McKinsey estimated B2B stablecoin payment volume at roughly $390 billion in 2025.

The push into corporate banking reflects a broader shift as stablecoin infrastructure providers target the $1.2 trillion subscription economy projected by 2030. Hyundai Motor recently completed a $20,000 cross-border treasury settlement using Tether's USDT on the Avalanche blockchain in about seven minutes, materially faster than traditional bank transfers that typically take three to four hours. Confirmo launched Subscribe, a recurring stablecoin billing service supporting USDC and USDG on Solana and Polygon, developed alongside proprietary trading firm FTMO. Wells Fargo and several major US banks also announced a shared network for tokenized bank deposits operated by The Clearing House, positioning the initiative as a direct response to stablecoin growth.

Flex's $70 million raise signals growing venture appetite for stablecoin infrastructure that bridges digital assets with traditional business banking. The company's platform allows businesses to manage stablecoin balances alongside cash positions, targeting the same efficiency gains that have driven pilots at Hyundai and adoption across Latin American payment corridors. As more enterprises test stablecoin settlement for cross-border payments, intercompany transfers, and recurring billing, the infrastructure layer connecting digital dollars to corporate treasury systems is becoming a focal point for investors.
