Let’s talk about a quiet revolution happening in men’s health, and no, it’s not another DTC startup selling shame in a box with sleek branding and a promo code.
Fellow Health just closed a $24M Series B, led by the deep science minds at 5AM Ventures, with fresh conviction from The Forest Road Company. That’s $48M total backing a company most people didn’t even know existed until their urologist quietly handed them a box and said, “You can do this at home.” And that’s the point. Fellow Health didn’t come to make noise, they came to make male reproductive diagnostics actually work.
Headquartered in San Leandro, CA, with a CLIA-certified lab that runs tighter than an Olympic relay team, Fellow Health isn’t just throwing tests in the mail. Their proprietary preservative keeps semen samples viable for up to 10 days. That’s not convenience, that’s science, with receipts. The company’s results aren’t just “good for home testing,” they’re clinically validated to match in-clinic benchmarks. Peer-reviewed. Published. Tested in 100,000+ patients. That’s not MVP energy, that’s precision execution at scale.
CEO Brian Hogan stepped up from CFO in 2024 and now runs point on a business seeing 40% YoY revenue growth and a 50% jump in testing volume over 2023. Co-founder Will Matthews, who started this whole thing back in 2018, still sits on the board after building the operational and scientific foundation that got them here. And this isn’t two dudes and a slide deck, this is a real company with real R&D, a secure courier network, and a clinical partner base that spans 2,500+ practices in all 50 states.
Fellow Health is pulling compliance numbers most clinics only dream about, 82% mail-in test completion post vasectomy, versus a national average that would make you question the whole system. Their liquid biopsy research? Published in PLOS One, unlocking cfDNA potential for next-gen prostate cancer diagnostics. This isn’t “disruption,” this is correction. A long-overdue course adjustment in how men are treated, medically and systemically.
So no, Fellow Health isn’t making noise. They’re making moves. And if you’re in fertility, urology, or building employer-sponsored benefits, you should be talking to them.
