Burst, a healthcare payments platform that helps retailers and wellness brands unlock billions in untapped FSA and HSA spending, has raised $3 million in total funding, including a $2.1 million seed round led by Pear VC. The capital will accelerate product development and fuel partnerships with retailers, e-commerce brands, and plan administrators looking to capture more health spending.

Why it matters

Burst's platform has already demonstrated strong traction with wellness brands and retail partners, driving up to 30% higher customer basket size and up to 42% increase in retention rates. The company aims to make it effortless for shoppers to use their pre-tax healthcare dollars on eligible purchases while keeping checkout simple.

The details

Unlike traditional FSA/HSA payment solutions that require new payment methods or checkout modifications, Burst works entirely post-purchase. Retailers keep their existing payment stack, checkout flows, and tooling. Shoppers pay as they normally would with Apple Pay, credit cards, or loyalty rewards. After purchase, Burst identifies HSA/FSA-eligible items, notifies customers of their savings opportunity, and files reimbursement claims automatically with their plan administrator.

What they’re saying

“We can help activate more of your customers to look like your best segment. HSA and FSA cardholders are already retailers' most loyal customers, returning often and spending more when they do. We eliminate the friction and empower consumers to use their pre-tax health benefits at your storefront.”

— Anthony Rangel, co-founder and CEO at Burst (USA Today)

“Every attempt we've seen to unlock HSA and FSA spend requires merchants to change how they sell and customers to change how they buy. Burst flips that model by fitting into existing systems-turning reimbursement into an asset for retailers and making it effortless for customers to use their HSA and FSA funds. That's what makes the platform scalable and gives it the potential to reshape how health spending actually flows.”

— Ajay Kamat, Partner at Pear VC (USA Today)

“The FSA and HSA world has been historically fragmented and purposefully difficult to navigate. We're building the abstraction layer that makes these accounts actually work for people, becoming the center of their health and wellness spending without them having to think about it.”

— Shubhi Jain, co-founder & Chief Product Officer at Burst (USA Today)

What’s next

Burst is actively hiring across engineering and partnerships and welcomes inquiries from retailers and wellness brands.

The takeaway

Burst's platform aims to make it easier for consumers to use their pre-tax healthcare dollars on eligible purchases, while also helping retailers drive higher conversion, retention, and customer lifetime value without changing their existing checkout flows.
