Flex has secured a $70 million Series B1 funding round led by Halo Fund, reaching an estimated valuation of $1.2 billion. According to Reuters, the new valuation is more than double the company’s previous mark from just six months ago, reflecting strong investor confidence in its AI-powered banking platform for mid-sized businesses.

The reported valuation and financial figures come from sources familiar with the deal rather than an official company announcement.

AI Banking Built for Mid-Sized Businesses

Flex focuses on businesses that often fall between consumer-focused fintech solutions and traditional banking services. Its platform combines credit, treasury management, cross-border payments and AI-powered financial tools into a single experience.

One of its key products, Beacon AI, provides business owners with regular insights into their financial performance. CEO Zaid Rahman told Reuters that the company is growing approximately four times year over year, has reached a nine-figure annualized revenue run rate and now serves several thousand customers. Flex also plans to expand its workforce from around 110 employees to more than 200 by the end of the year.

Stablecoins Become Part of Everyday Business Payments

A notable part of Flex’s growth comes from Flex Global, its international payments platform. According to Forbes, the company processes more than $1 billion annually through stablecoin payment rails, contributing to roughly $10 billion in annualized payment volume across more than 100 countries and 32 currencies.

The figures suggest that stablecoins are becoming increasingly practical for mainstream business payments rather than remaining limited to crypto-focused companies.

What Comes Next

While Flex’s reported growth is impressive, important questions remain around the company’s lending operations, including the structure of its credit facilities and long-term loan performance. As the business continues to scale, these factors will likely become key indicators of its long-term success.
