It works by letting clients keep funds on the platform, which accrues interest, while offering real-time reporting, expense management, card issuance, and fee-free payments; revenue comes from service fees and interest on client cash. It differentiates itself by combining high-interest cash potential with a full set of banking tools in one platform, plus ongoing security audits and fraud protections. Its goal is to help businesses maximize cash utility and profitability by streamlining financial operations and providing cost-effective payments with added rewards, all supported by strong security.

Flex raises $70 million to improve payments for high net worth business owners.

Flex raises $70 million to improve payments for high net worth business owners. * Business banking platform Flex raised $70 million in a Series B1 round to expand its business finance, payments, private credit, and ERP offerings while doubling its workforce. * The company also launched Flex Global, a cross-border banking service that combines multi-currency accounts, global payments, and stablecoin infrastructure to enable faster international money movement. * With Flex Global, Flex is positioning itself to compete more directly with Brex and Ramp by offering globally active businesses a unified platform that blends banking, payments, credit, and wealth management. The business banking space is heating up again. Business banking platform Flex landed $70 million in a Series B1 investment, boosting its total equity funding to $180 million and total debt funding to $300 million. Halo Fund lead the investment, which comes seven months after Flex's $60 million Series B round. Portage Ventures, Wellington, Crosslink Capital, 53 Stations, Titanium Ventures, Spice, Florida Funders, Spice, and others also contributed. Halo's participation is especially notable, as its co-founders span the sports and entertainment space, bringing expertise in sports and entertainment distribution into audiences that include millions of successful middle-market business owners and entrepreneurs. With this round, Flex plans to expand across business finance, personal finance, payments, private credit, and ERP. The company will also use the funds to double the team size from 110 employees to more than 200 by year-end. Flex made its debut in 2022 to bring private banking to high net worth business owners. The California-based company offers banking, private credit, payments, billing, and accounting tools for businesses, as well as a business credit card that pays up to 5% cashback. The company's average customer uses four or more of these products on its platform. Flex has crossed $10 billion in annualized total payment volume and is currently growing 4x year-over-year. "I've spent my career helping entrepreneurs win, and they all have the same problem: their business and personal financial lives are completely intertwined, but every bank treats them as two different customers, missing what they're actually trying to build," said Halo Fund Owner Co-founder Ryan Smith. "Flex is the first team creating a real private bank around the owner and the entire household's finances, and the gap they're filling is just as real globally as it is in the US. Zaid and the team have built an enduring business that is becoming an institution for the world's most ambitious owners." Along with today's funding announcement, Flex is launching Flex Global, a service that brings together local currency accounts, cross-border payments, and stablecoins for always-on, fast funds transfers. The service is aimed to serve cross-border businesses by issuing global credit cards, leveraging stablecoin payment rails and wallets in 100+ countries, and offering institutional USD accounts for foreign business owners. Flex's multi-currency accounts support 32 currencies across 76 countries, enabling busineses to hold, send, and receive funds in the currencies they actually operate in. Flex's goal is to make the underlying payment rails invisible to customers by embedding stablecoin settlement into its private banking experience. Rather than requiring businesses to manage crypto wallets or navigate blockchain technology, Flex uses stablecoins behind the scenes to make international payments feel as seamless as domestic ones. "Middle-market business owners are one of the most important and underserved customers in finance globally," said Flex CEO and Founder Zaid Rahman. "Depending on the type of owner, they'll tell you their vendors are spread across the US, Poland, Brazil, etc; their accounts hold currency outside of just USD; and they have to oscillate across 2-3 vendors and layers of fees just to do business outside their country." Flex Global raises the competitive stakes for Brex and Ramp by expanding Flex beyond domestic banking, credit, and expense management into global financial infrastructure. Both rivals already support international cards and vendor payments, while Brex has also been developing stablecoin-based global transfers. Flex differentiates itself with its focus on middle-market business owners and its effort to combine cross-border payments, multi-currency accounts, credit, banking, and personal wealth management within a single private-banking relationship. That approach could help Flex compete less as another spend-management platform and more as the primary financial institution for globally active entrepreneurs.

Ryan Smith's Halo Fund backs Flex in $70 Million Round

Ryan Smith's Halo Fund backs Flex in $70 million round. July 14, 2026 Sandy, Utah - July 14, 2026 Utah entrepreneur Ryan Smith has made another high-profile venture bet. Halo Fund, the investment firm Smith co-founded with Accel partner Ryan Sweeney, has led a $70 million funding B1 round for San Francisco fintech Flex, pushing the AI-native private banking company to a $1.2 billion valuation just six months after its previous financing. The deal underscores Smith's growing influence beyond Utah's startup ecosystem. Since founding Qualtrics and assembling a sports empire that includes ownership of the Utah Jazz and Utah Mammoth, Smith has increasingly turned his attention to venture investing through Halo Fund, backing companies that sit at the intersection of technology, artificial intelligence and global scale. While Halo Fund is closely identified with Smith and Utah, Flex is headquartered in San Francisco, where it was founded in 2023 by CEO Zaid Rahman. The company is building an AI-powered private banking platform for high-net-worth business owners and also maintains a New York office. Utah-based Halo Fund, launched by Smith and Sweeney in 2025 with offices in Sandy, Utah, and Palo Alto, California, led the $70 million investment. The fund positions itself as more than a traditional venture firm, leveraging Smith's reach across technology, professional sports and entertainment to help portfolio companies accelerate growth. Flex, headquartered in the Ferry Building overlooking the San Francisco Bay, announced the financing today. Founded in 2023 by CEO Zaid Rahman, Flex is building what it describes as an AI-native private banking platform for high-net-worth business owners. Rather than treating business and personal finances separately, the platform combines banking, payments, credit, expense management, treasury and AI-powered financial tools into a single system designed for entrepreneurs whose businesses operate across multiple countries and currencies. The company plans to use the capital to expand Flex Global, a platform that allows business owners to move money across more than 100 countries using stablecoin-based payment infrastructure. The company says the service supports banking in 76 countries and 32 currencies, enabling international payments to settle in minutes rather than days. For Flex, the timing is notable. The company says annualized revenue has tripled since closing a $60 million Series B in December 2025, while annualized payment volume has climbed past $10 billion. In total, the company has now raised $180 million in equity and $300 million in debt financing. Smith said Flex addresses a longstanding problem facing entrepreneurs. "I've spent my career helping entrepreneurs win, and they all have the same problem: their business and personal financial lives are completely intertwined, but every bank treats them as two different customers," Smith said in a statement. For Smith, the deal further expands Halo Fund's portfolio of growth-stage technology companies and underscores Utah's continued influence in venture investing. Since selling Qualtrics and building one of the country's most prominent sports ownership portfolios, Smith has increasingly focused on backing companies that combine artificial intelligence with large, underserved markets. With Flex now valued at $1.2 billion and targeting global expansion, Halo Fund is betting that private banking for entrepreneurs could become one of fintech's next major growth categories.

Halo Fund leads $70M investment into AI-Native Private Banking Platform Flex to accelerate the launch of Flex Global.

Halo Fund leads $70M investment into AI-Native Private Banking Platform Flex to accelerate the launch of Flex Global. The pre-emptive $70 million equity funding comes just six months after the last round as Flex expands its AI-native private banking platform to 100+ countries on stablecoin rails, banking and moving owners' money globally in minutes, not days. San Francisco, CA - July 14, 2026; Flex today announced a $70 million Series B1, led by Ryan Smith and Ryan Sweeney's Halo Fund with participation from Portage Ventures, Wellington, Crosslink Capital, 53 Stations, Titanium Ventures, Spice, Florida Funders, Spice, and others. The round comes just months after the company's $60 million Series B in December 2025. Annualized revenue increased 3x since then as Flex accelerated private banking for high-net-worth business owners globally. Halo Fund, co-founded by Utah Jazz and Utah Mammoth owner and Qualtrics founder Ryan Smith and Accel general partner Ryan Sweeney, brings a sports and entertainment platform spanning the NBA, NHL, and Formula 1. For Flex, the partnership pairs institutional depth with distribution into audiences that include millions of successful middle-market business owners and entrepreneurs, often in communities far beyond Silicon Valley, the exact customers Flex Global is built to serve. With this round, Flex has now raised $180 million in total equity and $300 million in total debt for expansion across business finance, personal finance, payments, private credit, and ERP. Flex will double the team size from 110 employees today to more than 200 by year-end. "Middle-market business owners are one of the most important and underserved customers in finance globally," said Zaid Rahman, CEO and Founder of Flex. "Depending on the type of owner, they'll tell you their vendors are spread across the US, Poland, Brazil, etc; their accounts hold currency outside of just USD; and they have to oscillate across 2-3 vendors and layers of fees just to do business outside their country." Silicon Valley built financial software for companies, and it built financial software for consumers. It largely missed the people who are both. In the US alone, roughly 350,000 high-net-worth business owners help drive 40% of private-sector payroll, yet most still run their financial lives through tools that treat the business and the owner as two separate worlds. Globally, an estimated 3 million such owners sit at the center of a meaningful share of private economic activity and nearly all of them are multi-entity, multi-currency, and multi-jurisdiction by default. Ryan Smith, co-founder of Halo Fund and owner of the Utah Jazz and Utah Mammoth, led the round as a strategic investor and commented: "I've spent my career helping entrepreneurs win, and they all have the same problem: their business and personal financial lives are completely intertwined, but every bank treats them as two different customers, missing what they're actually trying to build. Flex is the first team creating a real private bank around the owner and the entire household's finances, and the gap they're filling is just as real globally as it is in the US. Zaid and the team have built an enduring business that is becoming an institution for the world's most ambitious owners." A business built for global owners The high-net-worth business owner rarely operates in a single country or a single currency. Today, Flex is launching Flex Global. Building financial infrastructure for that reality: * Stablecoin payment rails and wallets in 100+ countries, settling cross-border payments in minutes * Institutional USD accounts for foreign business owners who need access to the world's reserve currency * Multi-currency accounts across 76 countries, supporting 32 currencies from USD to RMB to INR to MXN, so owners can hold, send, and receive in the currencies they actually operate in * Private credit solutions in 20+ countries, extending Flex's underwriting well beyond US borders * Cards issued to businesses operating globally, spanning entities and geographies under one platform The result is a single financial home that follows the owner wherever their business takes them. The company today * Flex has crossed $10 billion in annualized total payment volume, growing roughly 4x year-over-year at a nine-figure annualized revenue run rate * The average Flex customer now uses four or more products on the platform, a signal of the compounding relationship Flex is built to create, where each product deepens the value of the next * Flex's three largest business categories by logo count are construction, wholesale, and multinational businesses For two decades, fintech served two markets: mass-market banking for consumers, and corporate workflows for venture-backed startups and large enterprises. It largely bypassed the high-net-worth business owner, who operates across multiple entities, currencies, and jurisdictions, because the rails to serve them globally didn't exist. Over the past eighteen months, they arrived. Stablecoin legislation in the US and Europe made the rails enterprise-ready, the world's largest payment networks moved from pilots to production, and Visa's stablecoin settlement volume reached a multibillion-dollar annualized run rate. Real-economy stablecoin payment volume roughly doubled in 2025, the majority of it B2B. Flex's bet is that the winners of this shift won't be the companies that make owners think about stablecoins, they'll be the ones that make the rails invisible. Flex Global embeds stablecoin settlement underneath a full private-banking relationship: an owner pays a vendor in Warsaw or Mexico City the way they'd pay one in Dallas, with AI helping them make decisions across their entire balance sheet. The customer never touches a wallet; their money simply moves in minutes. What Flex is building Flex is the AI-native private banking platform for high-net-worth business owners in the middle market globally, built around five pillars: private credit, a business-finance stack, a personal-finance stack, payments, and an agentic back office finance operating system built for middle-market companies. Today the platform brings together credit, banking, payment processing, bill pay, expense management, treasury, and enterprise finance AI agents including Beacon AI. Over time, Flex plans to expand its global banking, personal credit and rewards cards, treasury, travel, and mortgage offerings. About Flex Launched in 2023, Flex is the AI-native private bank for high-net-worth business owners in the middle market, built on a five-pillar strategy spanning private credit, business finance, personal finance, payments, and ERP. Flex supports every step of an owner's financial life, from the moment they earn revenue to the moment they spend it personally. Visit www.flex.one.

AI finance startup Flex doubles valuation to $1.2B with $70M funding round

Flex, an AI startup offering banking services for mid-sized businesses, has raised $70 million in a funding round led by Halo Fund. A source close to the deal said the B1 round valued the three-year-old company at around $1.2 billion, more than double its valuation six months ago. The company has now raised $180 million in equity and $300 million in debt. Flex targets mid-sized businesses earning tens to hundreds of millions of dollars in annual revenue, a segment CEO Zaid Rahman says is overlooked by traditional fintechs. Unlike AI startups focusing on individual tasks, Flex bundles private credit, business finance, personal finance and payment tools into one platform. The company said it has a few thousand customers and is growing roughly four-fold year-over-year at a nine-figure annualised revenue run rate.
