Built by a Woman, for Women: Introducing Whole in One Health

In today’s healthcare landscape, we are surrounded by data from electronic health records (EHRs) and wearables to apps, symptom trackers, and paper documents. But instead of empowering us, this information often exists in silos, disconnected from one another and from the people it’s meant to help. That’s where Whole in One Health™ comes in.

Whole in One Health is developing an AI-powered, equity-driven personal health data hub designed to securely integrate user-authorized EHRs with self-reported and wearable data. By centralizing fragmented health information, the platform delivers culturally and linguistically responsive insights while prioritizing algorithmic transparency and fairness. The goal? To make health data more accessible, understandable, and actionable for both patients and providers.

This isn’t just a health tech innovation, it’s a movement built by a woman, founder Britt Massei, to address the needs of those historically left behind by traditional systems, starting with women in midlife, who make the majority of healthcare decisions in the U.S. and remain one of the most underserved populations.

A New Era for Health Data: Your Forever Home

At the core of Whole in One Health is a secure, intelligent personal health hub where members can store all their health data, whether from EHRs, apps, devices, CDs, or even memory. This is your Forever Home for health: a place where all your records finally live together in one easy-to-access, user-owned space.

Unlike traditional platforms, Whole in One Health doesn’t stop at collecting data. It transforms that data into personalized Action™, Insight™, and Alert™ tools. These tools help users take early, preventive action and make smarter decisions about their care. Health data becomes meaningful, actionable, and empowering.

Smarter Interactions, Stronger Connections

The rise of digital health tools, AI adoption, and a growing understanding of chronic conditions create a critical opportunity. Whole in One Health meets this moment by:

  • Ensuring interoperability across fragmented systems
  • Delivering timely, personalized insights powered by AI
  • Supporting early intervention and prevention
  • Enhancing remote interactions between patients and providers

This integrated approach strengthens the provider-patient relationship, empowers users to actively manage their health, and improves outcomes at the population level.

And as the system moves, albeit slowly, toward value-based reimbursement for digital health, Whole in One Health helps close the gap. Providers are better positioned to be compensated for reviewing and acting on patient-generated data, making care more equitable, efficient, and connected.

Marketplace, Sharing, and the Power of Choice

The platform’s upcoming Marketplace™ will feature curated, personalized health resources, from books and apps to providers and products, backed by a novel ratings system fueled by real user data. Rather than sifting through a sea of options, members receive tailored recommendations that actually fit their lives.

Additionally, the Share™ system allows users to selectively share data with Trusted Individuals™ (like family or doctors) or Organizations™ (like researchers or public health bodies). Members retain full ownership and control, and even have the opportunity to earn Rewards™ for contributing to research and innovation.

Imagine researchers having access to longitudinal health data from millions of diverse users, data that’s ready, relevant, and responsibly shared with consent. Whole in One Health makes this a reality, powering discovery while keeping users informed and in control.

Why It Matters

We’re still in the data age of health, while most industries have entered the information age. Whole in One Health is bridging that gap. As Britt Massei explains, “If we had enough data, we would know the cause of every human ailment.” And now, with the right tools, that future feels within reach.

From our first app AlzMeter™, focused on Alzheimer’s risk reduction, to our new MVP launching in 2025, Whole in One Health has remained mission-driven: to empower and inspire people to live better lives through better health.

We’re starting with midlife women, but this platform is built for everyone.

Whole in One Health isn’t just another app. It’s a foundation for a more inclusive, intelligent, and human-centered health ecosystem. Because every person deserves a home for their health, and the power to make it their own.
