Our take

Flex, formerly known as Flexbase, supplies credit and finance management tools for small and midsize business (SMBs). At the core of its offering is a credit card, with a complimentary platform that collects all finance operations into one easy-to-manage app.

Perhaps the most intriguing part of Flex's approach is the credit card itself, which comes with 0% interest for 60 days. Through this, businesses can enhance their cash flow and be more flexible in investing in growth. Besides this, users can also issue virtual employee cards at no extra cost, and use functions such as receipt capture and free ach/wire payments.

Having steadily grown its offering over the years, Flex has raised significant funding to expand its business and accelerate growth. Demand for its solutions has expanded beyond its initial focus on the construction industry to target clients across logistics, e-commerce, real estate and other sectors. After raising $85 million over two rounds in 2025, Flex has launched a Google Pay partnership and the Visa Infinite Business Credit Card, with enhanced benefits for business owners.
