Truemed Secures $34M in Series A Funding for HSA and FSA Payment Marketplace

Every few years a company shows up that does not beg for attention. It just quietly rearranges where the money flows. TrueMed just did exactly that, closing a $34M Series A led by Andreessen Horowitz, with Bessemer Venture Partners, Long Journey Ventures, BoxGroup, and Trust Ventures in the room. This is not wellness theater. This is infrastructure capital aimed straight at how Americans actually pay for health.

Justin Mares did not build TrueMed to sell vibes, powders, or slogans. He built a payments and compliance engine designed to unlock $159B already parked in HSA accounts, plus another $30B+ sitting in FSAs. Same dollars, different outcome. If prevention actually matters, then exercise, sleep, nutrition, and recovery should not live outside the tax advantages created for healthcare in the first place.

The numbers tell the story without raising their voice. 3x revenue growth YoY for two straight years. Over 3,000 merchant partners including Peloton, Eight Sleep, Nike Strength, Equinox, Barry’s, CorePower Yoga, and CrossFit. Roughly 40M HSA accounts in circulation, growing steadily, with consumers pulling $23B out in the first half of 2025 while contributing $33B. People are already spending. TrueMed just removed the toll booth.

Under the hood is where this gets serious. Clinician-led medical necessity reviews. Letters of Medical Necessity issued under IRS Section 213(d). A clean eligibility framework that separates what qualifies, what might qualify, and what does not. Shopify integrations that take minutes, not quarters. Compliance as product, not compliance as legal fine print.

The founding arc matters. Justin Mares is a repeat operator who knows how to scale consumer health brands without losing the plot. Calley Means helped shape the early thesis, then stepped away to serve as Senior Advisor at the U.S. Department of Health and Human Services, leaving TrueMed focused, founder led, and execution first. That clarity shows up in how the company moves.

Julie Yoo and Daisy Wolf at Andreessen Horowitz did not back a trend. They backed a market structure shift. Mark Hyman’s early support signaled clinical credibility. The Navia Benefit Solutions partnership opened the door to employer benefits at scale. This is how platforms win quietly, by becoming the pipe everyone else depends on.

TrueMed is not asking consumers to spend more. It is letting them spend smarter, pre-tax, and aligned with how health actually works. When prevention stops being treated like a hobby and starts being treated like healthcare, the money follows. This round is not a victory lap. It is a pressure test on whether healthcare dollars can finally grow up and work as hard as the people earning them.
