We’re excited to announce that we have raised $60 million in Series B equity funding, led by Portage. As of this round, we’ve raised a total of $105 million in equity to build the financial platform designed specifically for mid-market business owners.

With this new round of funding, we are ready to continue redefining owner finance. 

‍This investment follows a period of extraordinary performance. Over the last year, we have:

Grown Revenue 4X. Launched personal finance. Tripled our private credit offerings. Introduced a new suite of AI-powered tools.

Solving the Most Overlooked Problem in Finance

Most middle-market business owners manage complex companies, significant personal assets, and multi-entity financial lives. Yet the tools available to them have historically been built for someone else: Either small businesses with basic needs, or large enterprises with deep operational teams.

That gap is where Flex has built its edge.

The company’s mission is to give these owners a single, modern platform to run every dimension of their finances, including business and personal, supported by intelligent systems that anticipate their needs and simplify daily decision-making.

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

Zaid Rahman, Founder and CEO said of Flex. “Middle-market business owners employ 40% of Americans, but the financial system has never been designed around their complex needs.”
