San Francisco-based fintech company Flex announced the new funding round on Tuesday, saying the capital will strengthen its position as an AI-powered private banking platform serving high-net-worth business owners operating across multiple countries and currencies.
The Series B1 round was led by Ryan Smith and Ryan Sweeney’s Halo Fund, with participation from Portage Ventures, Wellington, Crosslink Capital, 53 Stations, Titanium Ventures, Florida Funders, Spice and other investors.
The latest investment follows Flex’s $60 million Series B completed in December 2025. Since then, the company said its annualised revenue has tripled as demand for its AI-powered financial services continues to grow.
With the new capital injection, Flex said it has now raised a total of $180 million in equity financing and $300 million in debt financing to expand its offerings across private banking, payments, business finance, personal finance, enterprise resource planning (ERP) and private credit.
The company also plans to increase its workforce from 110 employees to more than 200 before the end of the year.
Flex Global Targets Cross-Border Business Owners
At the centre of the company’s expansion strategy is Flex Global, a platform built for entrepreneurs and business owners whose financial activities span multiple countries, currencies and business entities.
According to Flex Founder and Chief Executive Officer, Zaid Rahman, middle-market business owners remain one of the most underserved segments in global finance despite their enormous contribution to economic growth.
He noted that many entrepreneurs operate businesses across several countries and currently rely on multiple financial providers to manage cross-border transactions, resulting in higher costs and operational complexity.
What Flex Global Offers
Flex said the new platform provides a unified financial ecosystem designed specifically for internationally active business owners.
Key features include:
Stablecoin payment rails and digital wallets across more than 100 countries.
Institutional U.S. dollar accounts for international business owners.
Multi-currency banking across 76 countries, supporting 32 global currencies, including USD, RMB, INR and MXN.
Private credit solutions available in over 20 countries.
Business payment cards supporting multinational operations across different jurisdictions.
The company said the platform enables customers to move money globally within minutes without directly interacting with cryptocurrency wallets, as the stablecoin infrastructure operates behind the scenes.
Payment Volume Exceeds $10 Billion
Flex disclosed that it has exceeded $10 billion in annualised payment volume, representing approximately fourfold year-on-year growth.
The company added that the average customer now uses four or more Flex products, reflecting growing adoption of its integrated financial ecosystem.
Construction companies, wholesale businesses and multinational enterprises currently represent the platform’s three largest customer segments.
Why Stablecoin Infrastructure Matters
Flex believes recent regulatory developments in the United States and Europe have accelerated enterprise adoption of stablecoin payment technology.
The company said improved regulation, increasing institutional adoption and growing business-to-business (B2B) stablecoin transactions have created the infrastructure needed to support global private banking at scale.

Rather than exposing customers to cryptocurrency complexity, Flex said Flex Global embeds stablecoin settlement within a traditional banking experience, allowing international payments to be completed seamlessly and significantly faster than conventional banking systems.
Halo Fund Backs Global Expansion
Ryan Smith, co-founder of Halo Fund, described Flex as one of the first companies building a comprehensive private banking platform focused on business owners rather than treating business and personal finances as separate relationships.
He said the investment reflects Halo Fund’s confidence in Flex’s long-term vision of serving entrepreneurs whose financial lives increasingly extend beyond national borders.
Halo Fund focuses on helping high-growth companies expand through technology, sports and entertainment partnerships, leveraging the networks built by its founders across Qualtrics, Accel, the NBA, NHL and Formula One.
