Flex, a San Francisco-based AI-native private banking platform for high-net-worth business owners in the middle market, has raised a $70 million Series B1 led by Halo Fund, the investment platform co-founded by Utah Jazz and Utah Mammoth owner and Qualtrics founder Ryan Smith and Accel general partner Ryan Sweeney. Portage Ventures, Wellington, Crosslink Capital, 53 Stations, Titanium Ventures, Spice, Florida Funders and others also participated. The round comes just months after Flex's $60 million Series B in December 2025 and brings total equity raised to $180 million and total capital including debt to $300 million. Annualized revenue has grown 3x since the December round, and Flex is now at a nine-figure annualized revenue run rate with more than $10 billion in annualized total payment volume, growing roughly 4x year over year.
