## About

Founded in 2023 by co-founders Sam Okeefe and Miguel Toledo and based in California, US, Flex Technology Co provides a comprehensive solution for businesses to accept health savings account (HSA) and flexible spending account (FSA) payments to pay for qualified health-related purchases using tax-advantaged funds.
Flex Technology's primary product is the Flex Shopify Payment App, which integrates into the Shopify platform, allowing merchants to accept HSA/FSA payments seamlessly during the checkout process. By ensuring compliance with healthcare spending requirements, Flex enables merchants to offer a broader range of payment options to their customers. The app also assists businesses in determining if their products qualify for HSA/FSA payments, whether auto-substantiated or requiring a letter of medical necessity (LOMN). The firm market has over 60 million Americans holding HSA/FSA accounts, and the total available funds exceed $150 billion. The company's products support various sectors, including e-commerce, fitness, wellness, and women’s health. In September 2025, Flex Technology Co. raised USD 15 million in series A funding co-led by Core Innovation Capital and First Round Capital, with participation from Cameron Ventures, Rethink Capital Partners, Liquid 2 Ventures, Precursor Ventures, SV Angel, and Y Combinator. Other unspecified investors also participated in the round. Flex Technology Co. generates revenue by enabling retailers to accept HSA/FSA payments, boosting conversions and order values.

The company plans to utilize the September 2025 funding for Health Savings Account and Flexible Spending Account payment system infrastructure expansion, retailer integration platform setup, and consumer eligibility compliance engine deployment.
