Flex AI fintech raises $70 million, valuation hits $1.2 billion

Flex secured $70 million in a B1 funding round that values AI‑driven fintech Flex at roughly $1.2 billion, more than twice its valuation six months earlier [2]. The capital will fund a global rollout, marketing push and a headcount increase to over 200 employees, positioning Flex to capture the underserved middle‑market business‑owner segment.

Funding and valuation surge

The B1 round, led by Halo Fund and joined by returning investors Portage Ventures and Crosslink Capital, brings Flex’s total equity financing to $180 million and its debt load to $300 million [2][4]. A source close to the deal confirmed the post‑money valuation of about $1.2 billion, a jump from the roughly $600 million valuation reported after the December 2025 Series B [2]. Flex did not disclose the valuation itself, but the figure aligns with the company’s claim of four‑fold year‑over‑year growth and a nine‑figure annualized revenue run rate [2].

Expansion into stablecoin‑based global payments

Coinciding with the financing, Flex launched “Flex Global,” a stablecoin‑powered cross‑border payments service that enables transfers in over 100 countries and supports balances in 32 currencies [2][3]. The service aims to reduce friction for “jumbo shrimp” businesses—mid‑sized firms generating $3 million to $100 million in revenue—that often rely on fragmented banking solutions [2]. PitchBook analyst Rudy Yang noted that stablecoin adoption in business banking is “inevitable,” underscoring the strategic timing of Flex’s rollout [3].

Workforce and market positioning

Flex plans to double its staff from 110 to more than 200 by year‑end, reflecting the capital‑intensive nature of its expansion into international markets and product development [2][4]. The company’s platform now bundles business banking, private credit, payments, treasury management and personal finance, differentiating it from AI fintechs that focus on single functions such as bookkeeping or invoicing [2].

What to watch

• Flex’s first‑quarter earnings and any update on its annualized revenue run rate, given the rapid scaling claims.
• Adoption metrics for Flex Global, especially transaction volume and currency coverage, which will signal market acceptance of stablecoin‑based payments.
• Any regulatory developments affecting stablecoin use in cross‑border business banking, which could impact Flex’s growth trajectory.

The $1.2 billion valuation marks a clear inflection point for Flex, highlighting investor confidence in a unified AI‑driven financial stack for mid‑market owners. Whether the platform can sustain its four‑fold growth and translate its TPV surge into profitability remains to be seen.
