Progress does not happen by accident. It happens when someone decides that what exists is no longer good enough. The most influential women leaders of today are not waiting for systems to change. They are building new ones. They are asking harder questions, challenging long accepted limits, and creating solutions that improve how people live every single day.
Marina Pavlovic Rivas is one of those leaders. As Co-Founder and CEO of Eli Health, she is redefining how people understand their own bodies. Her journey did not begin with a market opportunity. It began with frustration. Despite being a data scientist and having successfully built and exited an AI company, Marina realized she lacked something deeply personal: meaningful, real time data about her own hormonal health. For someone who believed that information is power, the absence of that data felt unacceptable.
What started as a personal search for answers soon became a larger mission. Conversations with thousands of individuals revealed a shared reality. People were making daily decisions about stress, sleep, fertility, mood, performance, and aging without access to the biological signals driving those experiences. Hormone testing was slow, expensive, and disconnected from everyday life. The system was reactive when it needed to be proactive.
A Company Built from Lived Experience
Founded on the principle that information is power, Eli Health created the world’s first instant hormone monitoring system. The company did not begin with a product. It began with a need. Marina often says they created Eli because they needed Eli. That authenticity shapes every layer of the business.
Headquartered in Montreal, a thriving life sciences hub, Eli has spent over six years in research and development. Its in house R&D lab and manufacturing infrastructure allow the company to rapidly develop and produce highly sensitive, cost effective tests. Breakthroughs in nanotechnology, microfluidics, chemistry, artificial intelligence, and endocrinology made continuous hormone monitoring possible.
The result is a platform designed to make hormone testing as easy as brushing your teeth and as affordable as a coffee. What once required lab appointments, long waits, and clinical barriers can now happen at home in minutes.
Instant Hormone Intelligence
At the center of Eli’s innovation is Hormometer™, the first continuous hormone monitoring system. With a simple saliva sample and a smartphone, users can access lab grade hormone results in just twenty minutes. There is no lab visit, no waiting period, and no complicated equipment.
The process is intentionally simple. Users install the Eli app, collect a saliva sample using a cartridge, wait twenty minutes, and scan the test strip using their phone’s camera. Within seconds, the AI powered app translates the scan into clear results, tracked trends, and personalized recommendations.
Hormometer™ currently offers cortisol testing, allowing users to track daily stress rhythms, energy levels, and recovery. Progesterone tests are available for pre order, helping users understand cycle patterns and ovulation in real time. Testosterone and estradiol tests are also on the roadmap, expanding the platform’s ability to support strength, mood, focus, cardiovascular health, and overall vitality.
For Marina, this is not about isolated numbers. It is about building the first large scale longitudinal data set of daily hormone levels in history. Each test contributes to a broader understanding of how hormones shape human health over time.
An AI-Powered Personal Health Lab
The Eli app transforms a smartphone into an AI powered laboratory. It does more than display results. It interprets them in context. Users can view precise hormone readings along with a daily score that shows where they stand at a glance. Personalized insights explain what those levels may mean for mood, sleep, performance, and recovery. A built in health journal allows users to log symptoms and lifestyle notes, revealing patterns over time. Tailored protocols provide science backed recommendations for nutrition, habits, and measurement reminders calibrated to individual data.
Unified integration with Apple Health and wearable devices ensures that hormone data sits alongside other key metrics, creating a comprehensive health picture. This shift from reactive to proactive healthcare is central to Eli’s vision. Instead of waiting for symptoms to escalate, individuals can see patterns early and act with clarity.
Built on Science, Privacy, and Precision
Eli Health is not simply a consumer technology company. It is a science driven organization grounded in rigorous research. More than two thousand assay iterations were conducted to ensure accuracy and reliability. The company holds over twelve patented technologies, establishing itself as a category leader in hormone monitoring.
Its infrastructure supports continuous improvement, enabling the rapid development of new tests and innovations. At the same time, Eli is committed to the highest privacy standards. Users own their data, just as they own their health. Strong security frameworks ensure that personal information remains protected and under individual control.
The company also collaborates with expert physicians and researchers in endocrinology, longevity medicine, and women’s health. This expert led foundation reinforces Eli’s credibility and ensures that insights are grounded in clinical understanding.
A Membership Model for Consistent Insight
To make regular monitoring accessible, Eli offers a membership model starting at an affordable monthly rate. Automatic test kit delivery ensures users never miss a measurement, while unlimited app access allows continuous tracking and interpretation. This model reflects Marina’s broader philosophy. Hormonal health is not a one-time check. It is a continuous conversation with the body. By enabling regular testing, Eli helps users connect how they feel to what is happening biologically.
Thousands of users already rely on Eli to better understand stress, cycle shifts, recovery patterns, and energy fluctuations. Testimonials highlight a common theme. People do not just want to know what is happening. They want to understand why. Eli Health stands as proof that when women entrepreneurs lead with purpose, they challenge systems that have long gone unquestioned. By democratizing access to hormone intelligence, Marina and her team are reshaping preventive healthcare and empowering individuals to take control of their wellbeing.

As a data scientist and entrepreneur, Marina has always believed information is power—especially when personal, actionable, and scalable enough to impact millions of people. After the acquisition of her first AI company, Marina’s own health journey led to a simple yet profound insight: the essential data she needed didn’t yet exist. Eli was created to fill this gap.
