Flex Secures $60M Series B to Transform Finance for Mid-Market Businesses

Many middle-market business owners navigate complex operations, manage substantial personal assets, and juggle multi-entity financial structures. Unfortunately, existing financial tools have often been crafted for either smaller businesses with basic requirements or large enterprises equipped with dedicated teams. This leaves a significant gap for these essential business leaders.

Flex recognizes this gap and is strategically positioning itself to offer a comprehensive, modern platform tailored specifically for mid-market business owners. The company’s mission is to help these proprietors seamlessly manage their diverse financial needs—spanning both personal and business finance—using intelligent systems designed to streamline daily decision-making processes.

“Our mission is to build the private bank that ambitious business owners have always deserved.”

Zaid Rahman, Founder and CEO of Flex, emphasizes this need, stating, “Middle-market business owners employ 40% of Americans, yet the financial system is not equipped to meet their complex requirements.” This underscores the importance of developing solutions that cater specifically to this underserved demographic.

Establishing a Foundation with Leading Investors

Flex recently completed a funding round that attracted a diverse group of global fintech investors, with Portage leading the way. Other notable participants include Titanium Companies, Wellington, Reticulation Capital, Business on Ventures, and several others.

“Flex is building a category-defining financial institution,”

Jake Bodanis of Portage Ventures remarked, “The company has demonstrated that middle-market business owners are extremely valuable customers when presented with the right financial infrastructure.”

Harnessing AI for Financial Innovation

Flex has adopted an AI-driven approach, intentionally designing its systems to function as an intelligent financial operating system rather than simply layering AI onto existing frameworks. This novel architecture mimics the functions of a traditional finance team while introducing enhanced efficiencies.

Flex’s platform encompasses five core product areas: Private Credit, Business Finance, Personal Finance, Payments, and ERP. Features include:

• Subscription management at both business and multi-entity levels
• Automated workflows for expense tracking and payments
• Advanced cash flow management and optimization
• Back-office operations tailored for owner-operators
• Real-time insights derived from Flex’s Owner Intelligence platform

This innovative financial operating system minimizes manual labor, centralizes visibility, and empowers business owners to make swift, informed decisions—critical factors driving Flex’s growth.

Revolutionizing Credit Access

One of Flex’s standout features is its vertically integrated credit strategy, bolstered by an AI-powered underwriting system that allows for more accurate risk assessment. This approach broadens access to essential capital and addresses financial demands often overlooked by traditional banking institutions.

The Flex Net-60 Credit Card offers substantial financial flexibility, serving as a primary entry point for new customers. Once onboard, users frequently expand into Flex’s broader ecosystem, consolidating multiple services into a cohesive financial environment.

Creating a Comprehensive Financial Solution for Business Owners

With the recent Series B funding, Flex is poised to accelerate its product development and scale its intelligent AI infrastructure. The company is committed to crafting a complete financial stack designed specifically for mid-market business owners, supporting them throughout their professional journeys and driving towards generational wealth.
