Peri is on a mission to diagnose and treat perimenopause.
Peri launches Tuesday direct-to-consumer with its wearable wellness device, $449, that can detect and track symptoms associated with perimenopause like night sweats, hot flashes, anxiety and sleep disruption using the brand’s proprietary algorithm. Peri, which was unveiled at CES 2025, is owned by women’s health company IdentifyHer.
“We spent five years in research and development, working with [500] women to get to where we are now,” said Heidi Davis, cofounder of IdentifyHer. “We recognize that the fact that there is such a lack of data in women’s health across the board, and when you look at long term health for women, it’s very hard to understand why we go toward one disease and not toward another.”
The device is worn under the breast using adhesive and features two removable and rechargeable batteries so that there is never a data gap. It can be worn for up to 10 days. For Davis, Peri is a crucial innovation, as it provides women the necessary data to discuss their symptoms with their clinicians.
“All women have to go through perimenopause at some stage, and we know that 75 percent of women experience what we call life-disrupting symptoms,” Davis said. “Seventy percent of women that go to their clinician do not get help, and the main reason for that is that there’s no clear diagnostic test for Peri menopause.”
Given the lack of research focused on women’s health and the difficulty of diagnosing perimenopause given it is based on self-reported symptoms, Peri marks a significant shift in the market.
“There’s no data collected, and we don’t know what’s going on,” Davis said. “We can take action during that time at the minute to set ourselves up for better quality of life as we go through perimenopause but also toward that long term health. We were on a mission to close that health data gender gap.”
Based on the data, Peri provides customized action items for each user on a weekly, monthly and cyclical cadence.
While Peri is just launching its preorders, the team is already thinking about ways to expand the platform with additional tracking and insights, given the amount of symptoms associated with perimenopause. In addition, Peri will continue to look at how perimenopause and its symptoms correlate with risk for conditions like cardiovascular disease and Alzheimer’s.
“It starts in perimenopause because it’s an important phase of life, but we’re working on making it a much bigger product, and it’s a bigger mission than that,” Davis said.
