Woofun AI reports that Flex has achieved a $1.2 billion valuation following a strategic pivot toward artificial intelligence and stablecoin infrastructure, driven by founder Zaid Rahman and led by Halo Fund. This rapid appreciation marks a significant shift in how middle-market enterprises access global financial services, moving beyond traditional banking constraints.

The financial milestone was cemented on July 14 when Flex closed a $70 million Series B1 financing round, a deal that propelled the company's valuation to $1.2 billion in just seven months. This latest injection of capital brings total equity financing to approximately $180 million, while total debt financing stands at around $300 million. The speed of this valuation doubling is particularly notable given the compressed timeline between funding events, signaling aggressive investor confidence in the company's ability to scale its global operations and deploy the Flex Global platform.

This acceleration follows a previous major capital event in December 2025, when Flex secured a $60 million Series B round that valued the company at roughly $600 million. That earlier round was led by Portage Ventures and included participation from Titanium Ventures, Wellington Management, Crosslink Capital, Spice, and Florida Funders. The subsequent July 2026 Series B1 round maintained Halo Fund as the lead investor but expanded the investor roster to include 53 Stations alongside the returning participants of Portage Ventures, Wellington, Crosslink Capital, Titanium Ventures, Spice, and Florida Funders. The trajectory from a $600 million valuation in late 2025 to $1.2 billion by mid-2026 underscores the market's growing appetite for integrated financial operating systems.

Halo Fund, the primary backer of this latest round, represents a new force in venture capital established in 2025 by Ryan Smith and Ryan Sweeney. Ryan Smith, the founder of Qualtrics and owner of the NBA's Utah Jazz and NHL's Utah Grizzlies, partnered with Ryan Sweeney, a general partner at Accel, to launch the firm. Headquartered in Sandy, Utah, with additional offices in Palo Alto, California, Halo Fund manages assets worth approximately $1 billion. The involvement of such a high-profile fund, backed by leaders from both the tech and sports industries, provides Flex with significant credibility and resources as it navigates complex international markets.

The strategic focus of Flex is precisely defined by its target demographic: middle-market business owners with annual revenues ranging from $3 million–$200 million. These entrepreneurs operate primarily in construction, wholesale, and import-export sectors, managing businesses that often span multiple entities, currencies, and jurisdictions. In the United States alone, there are approximately 350,000 such business owners who contribute 40% of private-sector salaries, while globally, this cohort expands to around 3 million individuals who play a pivotal role in private economic activity.

Despite their economic significance, these owners face severe friction in traditional finance, often forced to juggle more than 20 different tools to manage cross-border transfers, fees, and delayed settlements. Flex aims to resolve this fragmentation by integrating business and personal finances into a single platform, ensuring fund flows are as seamless as local transactions.

Zaid Rahman, the founder of Flex, brings a unique background to this challenge, having dropped out of Columbia University to join Peter Thiel's Thiel Fellowship program. Established in 2011 by PayPal co-founder Peter Thiel, the fellowship selects around 20 young people aged 18–22 annually, providing them with $100,000 in funding over two years to pursue innovative projects outside traditional education. Rahman, a Thiel Fellow, previously founded an educational software company and an AI knowledge technology startup named Volley, which garnered support from JPMorgan and Mark Zuckerberg.

His family's deep roots in the traditional construction business gave him firsthand insight into the financial pain points of middle-market owners, including multi-country project management and multi-currency settlement pressures. Since 2020, Rahman has focused on Flex, adhering to a "Delta 4" product philosophy that demands a user experience significantly surpassing existing solutions. Following the 2026 financing, the team plans to expand from 110 members to over 200 by year-end, prioritizing talent in global compliance, AI engineering, and cross-border product development.

The company's growth trajectory reveals a steady buildup of products and market presence starting from 2022. In that initial year, the team completed the first round of product testing and early recruitment. By 2023, Flex launched its credit card, with transaction volume quickly exceeding $1 million, and completed the acquisition of Ghost Financial, bringing combined equity and debt financing to $120 million. The year 2024 saw the gradual introduction of Flex Banking, global payment capabilities, and B2B payment functions. By 2025, transaction volume surpassed $1 billion, and the company added bill payment and AP automation features. With the July 2026 financing finalized, Flex officially accelerated its expansion of Flex Global to over 170 countries. Post-financing metrics show that annualized revenue has increased threefold compared to the previous round, with annualized total payments exceeding $10 billion.

Notably, stablecoin transactions alone have contributed over $1 billion to this volume, and customers now use an average of more than four products, indicating rapidly increasing platform stickiness.

Woofun AI data shows that the technical architecture of Flex Global relies on stablecoins as the underlying payment mechanism, enabling instant cross-border settlement without manual wallet management. The platform supports stablecoin payments and wallet services in over 100 countries, allowing cross-border transfers to be completed within minutes. This stands in stark contrast to traditional SWIFT or wire transfers, which typically take 1–5 business days and incur fees ranging from 1%–6%. The stablecoin mechanism reduces these costs to well below 1% and allows for real-time locking of exchange rates.

Furthermore, Flex Global covers 76 countries and supports 32 currencies, including USD, RMB, INR, and MXN, allowing business owners to hold, send, and receive local currencies on the same platform while accessing institutional-grade USD accounts. The platform also introduces a global card function for flexible credit card issuance across entities and regions, while private lending solutions have expanded to over 20 countries. All these functions are integrated into a single dashboard that connects supplier directories, approval processes, and data sources, eliminating the need to switch between multiple systems.

AI serves as the core engine driving efficiency within this ecosystem, capable of integrating and analyzing corporate financial statements, bank statements, ERP system data, and industry-specific tools such as Procore data from the construction industry. Through automated credit assessment models, Flex reduces the traditional bank credit approval cycle, which often takes 90 days, to about 2 days. Previously, Flex's own internal approval process took 40–50 days, but AI technology has significantly accelerated this timeline.

This capability is critical for use cases like Net-60, a credit card offering 60 days of interest-free financing that helps construction companies maintain stable cash flow for material purchases and payroll. By analyzing comprehensive data sets including Procore records, the system enables business owners to seize growth opportunities without waiting for bank approvals. In the competitive landscape, Flex distinguishes itself from Brex, which focuses on tech startups, by targeting middle-market owners with annual revenues between $3 million and $200 million who require cross-border fund flows and unified financial management.

Market trends further validate this approach, with stablecoin B2B transaction volume growing by 733% in the past year to reach annual payment volumes of around $390 billion. Visa's annualized stablecoin settlement rate reached $7 billion in April 2026, representing a 50% increase quarter-on-quarter. The regulatory environment is also becoming more favorable, with the U.S. GENIUS Act and the EU's MiCA providing clear frameworks for stablecoin issuance. Flex leverages these infrastructures to create tools for daily business use rather than forcing owners to manage complex technologies. Currently, Flex has no plans to issue its own native token or disclose a public token economics model, relying instead on existing stablecoin infrastructure to serve cross-border needs.

As Flex accelerates its development, it must navigate significant challenges regarding regulation and credit risk. The stablecoin mechanism depends heavily on frameworks such as the GENIUS Act and MiCA, and global expansion requires obtaining licenses in multiple jurisdictions alongside rigorous anti-money laundering and sanctions screening. Even with faster settlements, end-to-end processes still involve handling foreign exchange, reconciliation, and reporting, where regulatory changes could impact development pace.

Credit business also demands caution, as private lending products like Net-60 rely on AI for approval, and middle-market companies' cash flows remain susceptible to industry cycles. As a fintech company, Flex relies on bank partners, making stability crucial. Nevertheless, through the latest financing and the rollout of Flex Global, the company has established a clear path forward, transforming stablecoins into underlying infrastructure and AI into faster decision-making to provide a unified financial hub for business owners in the construction, wholesale, and import-export industries.
