What is Flex?
Flex was founded with the objective of simplifying the acceptance of Health Savings Account (HSA) and Flexible Spending Account (FSA) payments for health and wellness brands. Historically, processing these specialized payments online was largely exclusive to major e-commerce platforms, forcing smaller merchants and their customers into cumbersome reimbursement processes. Flex aims to democratize this capability, making it seamless for a broader range of businesses to integrate these payment options at checkout, thereby enhancing customer convenience and expanding revenue streams for merchants.
How much funding has Flex raised?
Flex has raised a total of $18.2M across 2 funding rounds:
Angel/Seed
$3.2M
Series A
$15M
Angel/Seed (2024): $3.2M with participation from SV Angel, Precursor, Liquid 2 Ventures, and Y Combinator
Series A (2025): $15M led by First Round Capital, Core Innovation Capital, Cameron Ventures Group, Rethink Impact, and Y Combinator
