Upstream Fertility Health.

Most women trying to conceive aren't going to a fertility clinic. And they want to be pregnant yesterday.

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. FertiHealth closes that gap upstream: before the clinic, before the diagnosis, before the crisis. It keeps working alongside treatment once that has begun.

Every interaction is anchored in evidence-based clinical guidelines.

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

Four products, plus a path into real care: education, analysis, and coaching. 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. 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 Ferti, an AI built on physician-approved content.
    Generates baseline fertility-knowledge data across diverse user populations.
  2. Forecast
    CruScore
    Fertility, perimenopause, and longevity forecasts from a quick lifestyle and environmental survey.
    Produces the core lifestyle and environmental dataset that anchors longitudinal modeling.
  3. Act
    Ferti6
    Build the daily habits that change outcomes, with AI coach Viv and real human coaches behind you.
    Tracks behavioral change and coaching response data linked to fertility outcomes.
  4. Measure
    OvaSpan
    Hormone and metabolic biomarkers tracked over time, so you know where you stand in the menopausal transition.
    Adds the biomarker layer. First commercial application of STRAW+10 for reproductive aging prediction.
  5. Care
    Partner care
    A warm handoff to licensed clinicians: PCPs, OB/GYNs, and fertility specialists.
  6. The clinic
    $20K IVF
    Where the system starts today. Our products enhance the journey.

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

The data thesis

The dataset that makes prediction possible.

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 an opportunity to intervene. We focus on health, not on pregnancy — and 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. ARPA-H has called for exactly that. 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.

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: a fertility companion, innovative education, and AI coaching, to shorten time to pregnancy from anywhere.

I sit at the intersection of reproductive science, hormonal health, 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.
