How Flex is Scaling its AI-Native Finance for High-Net-Worth Business Owners

Flex, empowering business owners with a new approach to finance, led by Zaid Rahman, Hadi Solh, Robbie Figueroa, Vishal Saxena, David Toro, Luciano Arango, and others, has secured $60 million in Series B equity funding, led by Portage, and additional participation from Titanium Ventures, Wellington, Crosslink Capital, Companyon Ventures, Spice Expedition, Florida Funders, FirstLook Partners, MS&AD Ventures, Restive and others, bringing the company's total funds raised to $105 million in equity.

Most middle-market business owners operate complex companies, oversee substantial personal assets, and navigate multi-entity financial lives. Yet the available tools have traditionally served a different audience, either small businesses with basic requirements or large enterprises with extensive operational teams. Flex is addressing that gap.

The company’s mission centers on providing a single, modern platform that unifies every dimension of an owner’s financial world, business, and personal alike, powered by intelligent systems that anticipate needs and streamline daily decision-making.

“Our mission is to build the private bank ambitious business owners have always deserved,” said Zaid Rahman, Founder and CEO of Flex. “Middle-market business owners employ 40% of Americans, yet the financial system has never been designed around their complex needs.”

Flex is establishing a category-defining financial institution. Jake Bodanis of Portage Ventures highlighted the firm’s conviction, noting that middle-market business owners remain significantly underserved yet represent highly valuable customers when supported by the right financial infrastructure.

Flex operates as an AI-first financial institution built on an intelligent agent architecture that replicates a full financial team. These agents support private credit, business finance, personal finance*, payments, and ERP through capabilities such as multi-entity underwriting, automated workflows, treasury optimization, and real-time insights via the Owner Intelligence platform*.

The result is a unified operating system that reduces manual work, centralizes visibility, and delivers faster, data-driven decisions while supporting strong capital efficiency.

Flex’s vertically integrated credit model, powered by its AI-driven underwriting system, enables more precise risk assessment and access to tailored capital solutions often unavailable through traditional banks. Its Net-60 Credit Card remains a key entry point, with customers frequently expanding into Flex’s broader ecosystem, consolidating fragmented tools into a unified, more efficient financial environment.

The Series B funding will accelerate Flex’s product expansion, scale its AI agent infrastructure, and advance its goal of building a full financial stack for middle-market business owners. The long-term vision is bold: a unified platform that supports owners across their entire business lifecycle and into generational wealth.
