I’m proud to share that Flex has raised a $15M Series A to transform how Americans pay for their health and wellness. Americans have more than $150B in HSA/FSA accounts — money meant to make healthcare more affordable, but the barrier to using your HSA/FSA is way too high. Flex changes that. Our platform makes it easy for health and wellness retailers to accept pre-tax payments directly at checkout. Consumers save money, and businesses grow. With more consumers looking beyond traditional healthcare to invest in wellness, fitness, and preventative health, the opportunity for seamless HSA/FSA payments has never been greater. We’re already working with market leaders like Dermstore, Therabody and Omnilux, and this is just the beginning. I want to give a special shoutout to my exceptional cofounder Miguel Toledo and the entire Flex team. They are a fantastic group of dedicated people that I’m so excited to work with everyday. I’m also thrilled to be working closely with Liz Wessel from First Round Capital and David Roos at Core Innovation Capital. We also welcome Jenny Abramson from Rethink Impact, LP, and Aaron Webster from Cameron Ventures to the round. The future of consumer health spending is Flex.
