Eli

Eli Health is a Montréal-based health technology company that develops an instant, at-home hormone monitoring system called the Hormometer. Users collect a saliva sample on a single-use, thermometer-like cartridge and scan it with the Eli mobile app, which returns a hormone reading in about 20 minutes along with trend charts and AI-generated recommendations. No laboratory visit or sample shipment is required. Cortisol is the first biomarker available; progesterone and testosterone are announced as forthcoming, with waitlists and pre-orders open.

The product rests on roughly five to six years of research and development spanning biochemistry designed for microfluidics, custom hardware, computer vision and machine learning for interpreting test results, and endocrinology. The company cites more than 12 patent-pending inventions, about 2,000 assay iterations, and third-party validations; its marketing states 97% accuracy benchmarked against a laboratory reference method and upwards of 80% agreement with research-grade ELISA salivary cortisol measurement. The Cortisol Hormometer is positioned as a general wellness product rather than a diagnostic, while the Progesterone Hormometer is described as FDA-registered; the company has said it was pursuing Health Canada approval.

Eli operates its own R&D lab and in-house manufacturing facility in Montréal, which management describes as reducing exposure to supply-chain volatility and tariffs. The company states it is building a large-scale longitudinal data set of daily hormone levels. Its team includes co-founder and CEO Marina Pavlovic Rivas (data scientist, previously founded an AI company that was acquired), co-founder and CTO Thomas Cortina (mechanical engineering and physics background), COO Zoya Brar (founder of diagnostics company CORE Diagnostics), and medical director Fady Hannah-Shmouni, MD, an endocrinologist and geneticist at the University of British Columbia.

Founding story

Co-founder Marina Pavlovic Rivas, a data scientist whose first AI company was acquired, found during her own health journey that she had little data about her own body, and conversations with thousands of people indicated the same gap. With her partner Thomas Cortina, who has a physics and mechanical engineering background, she set out to make hormone data accessible, leading to five-plus years of R&D and the Hormometer.

Business model

Direct-to-consumer sales of single-use saliva test cartridges paired with a mobile app, sold primarily on subscription; the site also has a "For businesses" channel.

Subscription plans for tests starting at $8 per test on a 12-month commitment, with more flexible options available; tests are also sold through the company's online store.

Traction

Reached commercial readiness for its first two hormones after nearly six years of R&D, ran a live private beta and launched cortisol testing in beta, opened a progesterone waitlist, won CES 2025 Best of Innovation in Digital Health, and reported a 20-person team at the time of its Series A. Its site cites a 4.7 average customer rating.

Latest developments

Announced a $12M USD Series A in June 2025 to scale manufacturing, expand access and add biomarkers; cortisol tests are on sale with progesterone and testosterone listed as coming soon or available for pre-order, and the company said it hoped to obtain Health Canada approval.
