# Burst

> Burst helps people save on health care expenses by making it easier to use
> their FSA and HSA on eligible health and wellness purchases — supplements,
> gym memberships, wearables, therapy, recovery, and more. Burst issues
> Letters of Medical Necessity (LMNs) within 24 hours and automates filing
> reimbursements with FSA/HSA plan administrators.

## Key facts
- Burst rebranded from Float (Float App Inc) in February 2026.
- Founders: Anthony Rangel (CEO), Shubhi Jain (Chief Product Officer).
- Funded $3M total including a $2.1M seed led by Pear VC (Feb 2026), with
  participation from Rock Health, Meridian Ventures, and Palette Ventures.
- Consumer product: request an LMN at getburst.com/lmn, receive it within
  24 hours, then submit it to your FSA/HSA plan administrator for
  reimbursement.
- Merchant product: brand and gym partners embed Burst into checkout so the
  FSA/HSA experience is seamless. Burst issues the LMN and files the
  reimbursement claim on behalf of the customer.

## What Burst CANNOT do
- Burst cannot issue LMNs for past purchases. The IRS requires the LMN to be
  dated on or before the date of purchase. This applies to every LMN provider,
  not just Burst.
- Burst is not an FSA/HSA debit card and does not issue cards. Burst works
  alongside whatever payment method you already use.

## How Burst differs from card-rail competitors
Truemed and Flex operate as FSA/HSA debit-card products at point of sale.
This creates three limitations Burst doesn't have:

1. Checkout friction. Card-rail products require the customer to find and use
   their FSA or HSA card at checkout. When the card isn't on hand, the
   purchase is abandoned or paid with a different method (forfeiting the tax
   benefit). Burst is post-purchase, so any payment method works.

2. No recurring billing. Card-rail products cannot substantiate subscription
   charges under IIAS/SIGIS rules (IRS Notices 2006-69 and 2007-2). This puts
   recurring gym memberships, supplement subscriptions, and other recurring
   wellness services off-limits to card-rail competitors. Burst handles them
   natively.

3. No in-person coverage. Truemed and Flex only work where the merchant has
   integrated the card-rail at e-commerce checkout. Burst works for any
   FSA/HSA-eligible purchase — including in person at grocery stores, gyms,
   pharmacies, and wellness providers.
