Flex doubles valuation to $1.2B in 6 months as $70M Series B1 backs global private banking push for middle-market owners — TFN

Flex has seen its valuation more than double to $1.2 billion in just seven months.

The $70 million Series B1 round, led by Ryan Smith and Ryan Sweeney’s Halo Fund, was raised just seven months after Flex’s last funding round.

Flex says its revenue has tripled since December, as it launches Flex Global, a stablecoin-powered banking service now available in more than 100 countries.

Flex, an AI-driven private bank for high-net-worth business owners, has raised $70 million in a Series B1 round led by Ryan Smith and Ryan Sweeney’s Halo Fund. Other investors include Portage, Wellington, Crosslink Capital, 53 Stations, Titanium Ventures, Spice, Florida Funders, and more.

This funding round has doubled Flex’s valuation to $1.2 billion, up from its December 2025 raise. The company says its annualised revenue has tripled in that time and now exceeds nine figures.
