”At Elfie, we start where health truly begins—with patients. By making self-monitoring free, fun, and medically validated, we’re building the world’s most trusted health app—from the patient up, to pharma, insurers, and science.”

Ofir Ejnes

CEO & Founder

The ambition behind the mission.

At Elfie, our ambition is to become the world’s most used health app for patients to self-monitor their health. We believe preventive health starts from the bottom up—by empowering individuals first.

Our pyramid approach begins with patients: a free, gamified app that makes self-monitoring fun, simple, and rewarding. From there, we partner with global pharma leaders to deliver validated health programs, collaborate with insurers to expand access to care, and work with world-class researchers to advance science with real-world data.

By putting patients first, we create the trust and adoption that will ultimately make Elfie the #1 platform recommended not only by users, but also by doctors, insurers, and scientists worldwide.

The values drive everything we do

We recruit, assess, pay, promote, and fire based on our values.

Join our team

Sustainable impact

We’re here to improve lives. But real impact only matters if it can scale and sustain itself. That’s why we make decisions that balance patient outcomes with business growth.

Extreme ownership

We are accountable for outcomes, not just effort. When something breaks, we fix it. When we see a gap, we take initiative. We don’t wait to be told — and we don’t hide behind process, hierarchy, or good intentions.

Speak up

Silence protects egos, not outcomes. We expect everyone to voice concerns, question assumptions, and bring forward better ideas — clearly, respectfully, and with reason.
