Upstream infertility
and menopause.

Most women trying to conceive aren't going to a fertility clinic. They want to be pregnant already, but no one has shown them what to change. In perimenopause, they're just trying to get through the fog and chaos, and will take any plan they can get — if they're lucky enough to find a provider.

Hormones and fertility signal what's to come in their metabolic healthspan. This is our focus.

Why we exist

Women spend years preventing pregnancy with no roadmap for when they're ready to conceive. Then a fertility clinic runs $20,000 per IVF cycle. Perimenopause is worse. No warning, no roadmap. Just a gaping hole for women between family planning and senior care.

FertiHealth closes that gap upstream: before the clinic, before the diagnosis. Working alongside treatments once they've begun, for longitudinal care.

The upstream thesis

Others try. They leave women more anxious or worse.

Her cycle app picked a day and sounded certain about it. It's right about a quarter of the time. The Reddit thread at 1 a.m. is worse. A decade later she gets hot flashes and a constellation of other symptoms. And no one to show her how to thrive for the next three decades. She's being failed by a medical system that didn't train providers to look at menopause as anything but natural — fewer than one in ten finish residency feeling prepared to manage it.

What she gets from us is an answer from doctors who treat these women every day, grounded in peer-reviewed guidance from ASRM, SART, ACOG, ACLM, the Menopause Society, and the Endocrine Society — and one thing to change this week.

Four products for her, plus a path into real care: education, analysis, and coaching. One more for the people who treat her: clinical decision support, software for physician offices and health systems. A woman might use one or all four, on recurring subscriptions at a personalized cadence — one we recommend from her answers and her motivation to change. The span is deliberate: she may arrive trying to conceive and stay through perimenopause and the metabolic transition after it — the same biomarkers, read for a different reason. Every one feeds the same dataset, and the insights it will make possible.

  1. Understand
    GetFerti
    A companion who walks with you. Games, simulations, and physician-approved guidance, powered by Ferti.
    Generates baseline fertility-knowledge data across diverse user populations.
  2. Forecast

    Tracks behavioral change and coaching response data linked to fertility outcomes.
  4. Prevent
    OvaSpan
    Physician-designed interpretation of hormone and metabolic labs that turns perimenopause and menopause into a prevention plan.
    Ties reproductive aging to the metabolic transition that follows it.
  5. Care
    Partner care
    A warm handoff to licensed clinicians: PCPs, OB/GYNs, and fertility specialists.
  6. License
    Health systems
    Where the system starts today. We are building clinical decision support for the clinics and systems that treat her — to be used with providers, to make care easier.

The clinic opens its door after 12 months of trying. We start at −3.

The data thesis

Reproductive health is the gateway to metabolic health.

FertiHealth's products generate what doesn't exist today: a prospective, longitudinal dataset linking behaviors, biomarker trajectories, and reproductive outcomes.

Fertility apps track cycles. Wearables track biomarkers. Lab subscriptions return results without telling her what to change. Clinics run diagnostics after a 12-month delay. None of them connect guidance, coaching, and biomarker assessment into one pipeline. None have operationalized STRAW+10, the gold-standard framework for reproductive aging, at commercial scale.

Every cycle is a biomarker and an opportunity to intervene. We focus on health, not on the two lines and not menopause as a completion event. We never ask her whether this was the month, which would only add anxiety. When it happens, she tells us, with months of behavior and biomarkers already behind it.

As it grows, the dataset predicts fertility decline before it becomes infertility. Our architecture is built for it.

Fertility is where she arrives. Hormonal and metabolic health is what she stays for. The biomarkers that tell her how soon to act are the same ones that map the perimenopausal transition a decade later. Most fertility companies lose the user the moment she succeeds.

Every product feeds one dataset. Every user makes it more valuable. That compounding is the company's core asset. It is also what we are building to license: clinical decision support for health systems, designed to be used with providers rather than around them.

Women are drowning in health information, but legitimate care from a doctor is hard to come by. The gaps are growing. Women wait months to get a diagnosis and treatment for infertility, PCOS, endometriosis, recurrent loss, or perimenopause. I built FertiHealth to change that: education, forecasting, coaching, and lab interpretation, starting upstream of the clinic and continuing through perimenopause into her metabolic healthspan. Now I am building clinical decision support for the providers and health systems who treat her, to make that care easier.

I sit at the intersection of reproductive science, hormonal and metabolic health, longevity, and how people actually change. I co-authored Getting to Baby to reach the women who couldn't get to my office. FertiHealth is what comes next: the same evidence base, scaled beyond the exam room.

Women's health is a continuum. Let's talk about it that way.
