Business owners juggle a thousand financial decisions every day, from managing cash flow to separating personal and company expenses. For many, the line between business and personal spending blurs, creating headaches at tax time and complicating financial management. That’s where Flex steps in.
Flex, a Miami/New York fintech startup founded by Zaid Rahman, just announced that it has secured $25 million in equity funding, alongside a $200 million credit facility, to further its vision of making business finances simpler for mid-market company owners.
Titanium Ventures led this round with participation from Companyon Ventures, Florida Funders, MS&AD Ventures, AAF Management, and First Look Partners. Victory Park Capital provided the $200 million credit facility, which will support Flex’s credit card operations. In total, the company has raised $45 million in equity and secured $300 million in credit facilities.
Unlike corporate-focused platforms such as Brex and Ramp, Flex tailors its offering to business owners who also act as CEOs, many of whom run multi-million-dollar companies but lack access to financial tools designed specifically for their needs.
“Business owners tend to co-mingle their personal and business expenses, deposits, and payments, leading to accounting reconciliation issues and cashflow gaps,” Rahman told TechCrunch. “Our growth validates the demand from business owners for an all-in-one ecosystem that simplifies their finances.”
Investing again in Flex was an easy decision for Florida Funders. “Since the day Joey Levy [CEO of Betr] introduced me to Zaid Rahman, I knew Flex was an exceptional business,” Florida Founders Partner Saxon Baum shared on LinkedIn. “The drive and vision that Zaid and his team have are something that you do not see every day. We are excited to be an early investor in the business, and we could not be more excited for the next several years to see where this company can go!”
Flex’s origins trace back to a different industry entirely. Initially operating as a construction-focused platform, the company pivoted in 2022, shifting its focus to financial services. By September 2023, it emerged from stealth with a business credit card and expense-tracking product. Today, the company is an all-in-one finance platform that helps business owners manage their finances from revenue intake to personal spending.
With thousands of businesses already using Flex, the company positions itself as a “financial co-pilot” rather than just another fintech solution. Its clients range from logistics firms to grooming brands to construction companies.
Flex’s dashboard provides a real-time view of all financial transactions, allowing users to categorize expenses as business or personal with a simple tap. “All business entities and personal life sit in a single dashboard,” Rahman explained. “They can decide in-app which transaction is business and which is personal. This can be complex from a software and compliance standpoint.”
For many customers, switching to Flex meant leaving behind high-end financial products like the American Express Centurion (“Black”) Card. The average Flex customer generates $25 million in annual revenue, said Rahman, a Thiel Fellow and serial entrepreneur who also co-runs 305 Ventures.
He declined to disclose revenue figures but shared that Flex surpassed $1 billion in annualized total payment volume within just 18 months of launching its card and bill pay automation product. The company is currently growing at a rate of 25% month over month, and Rahman expects revenue to multiply by five in 2025.
As Flex scales, its team is expanding as well. At the end of 2024, the company had 64 employees, more than doubling its headcount from the previous year. With the latest capital infusion, Flex plans to build out its AI and B2B payments teams in New York and San Francisco.
