What is Burst?
Burst operates as a specialized fintech platform designed to automate the reimbursement process for Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA). By integrating directly with health savings providers, the platform removes the manual burden of filing claims for eligible wellness purchases. Beyond its core reimbursement engine, Burst offers a suite of consumer-facing tools, including a browser extension that identifies FSA/HSA-eligible products in real-time and a streamlined workflow for securing Letters of Medical Necessity (LMNs). This dual-sided approach serves both the end-user seeking convenience and the merchant looking to reduce cart abandonment for health-related goods.
