Sleep has become one of the most closely monitored aspects of modern life, with an estimated half of people globally using a wearable device to track it and an almost identical share ranking it as the most important behavior for health and longevity. Improving it, however, has proved far more elusive than measuring it.
Kimba is out to bridge that gap. It’s developed an artificial intelligence-driven bedside device that monitors sleep and integrates with wearable devices such as Oura Ring, Garmin and Apple Watch to determine when to release personalized scents throughout the night based on sleep patterns and biometric data. That targeted scent delivery, combined with the device’s ability to learn from users’ sleep data and optimize scent timing and selection, distinguishes it from a conventional diffuser.
To scale its device, Kimba has raised $5.4 million in seed funding in a round led by Selva Ventures with participation from Palette Ventures, Able Partners and Resolute Ventures, bringing its total funding to $6.5 million. According to Axios, which broke the news of Kimba’s launch and seed funding, the company plans to pursue a series A round in 2027.
“Unlike wearables that only give you data you measure, we actually show you what we did for you and how we improved your data,” says Ben Fuxbruner, co-founder and CEO of Kimba. “It’s very cool.”
Available for preorder at $299 and shipping in January, Kimba’s 1.3-pound device comes with three scent capsules selected from seven fragrances available at launch, including bright citrus, serene flower, orange blossom and lemon calm, part of a collection of 12 the company has formulated. It operates on a subscription model, delivering personalized scent refills every three months. Kimba aims to reach 10,000 subscribers in its first year.
Rana Taghdisi Argenio, founding partner at Palette Ventures, says, “Sleep is the foundation of physical and mental health, making it one of the most powerful daily rituals a company can own. Rather than selling another sleep aid or fragrance, Kimba is building an intelligent sleep platform that combines neuroscience, AI, biometrics, hardware and scent into a closed-loop system that becomes more personalized every night. We believe that’s the future of consumer: brands that don’t just fit into daily routines, they continuously improve them.”
Kimba’s origin story dates to 2014, when co-founder and CEO Ben Fuxbruner was injured in combat during the Gaza War while serving as a canine special forces commander in the IDF’s Oketz unit and his dog, Kimba, was killed. He subsequently battled post-traumatic stress disorder and insomnia, trying everything from sleep medications to wearable devices in an effort to get better sleep. That frustration inspired the creation of Kimba.
“We can actually engage with your brain while you sleep without waking you up.”
Transforming the idea into a commercial product took about a decade and roughly eight prototypes. Beyond the underlying technology, Fuxbruner and CTO Gabi Beck, a mechanical engineer, worked to make the device quiet, aesthetically pleasing enough to blend into a bedroom, compact enough for a bedside table, gender neutral and unobtrusive to a user’s sleeping partner. Fuxbruner originally envisioned Kimba as a device for people with PTSD, but soon realized poor sleep affects a far broader population.
Although Kimba’s recurring scent subscription appealed to investors, so did its commitment to scientific validation. In a clinical study of 50 participants conducted in 2025 and 2026, the company reports that 86% experienced improved sleep quality, nighttime disruptions declined 24%, REM sleep increased 32% and cognitive performance improved 21%. Kimba’s scientific advisors include sleep researcher Peretz Lavie, neuroscientist Anat Arzi and scent scientist Aharon Ravia.
Fuxbruner, who notes Kimba is in the middle of two other clinical trials, explains the device releases scent that triggers the olfactory-limbic pathway, allowing it to influence the brain without disturbing sleep. “We can actually engage with your brain while you sleep without waking you up,” he says. “By triggering the hippocampus in charge of memory, it can actually improve your brain’s ability to consolidate memories and enhance your cognition.”
Kimba is arriving as fragrance increasingly extends beyond beauty into functional wellness. Aromatherapy has long been associated with benefits like relaxation and better sleep, but newer brands like The Nue Co., Vyrao and Biology are applying modern branding and scientific research to position scent as a tool to reduce stress, sharpen focus, boost energy and influence mood rather than simply smell good.
Sleep is merely the beginning for Kimba. “Our near-term focus is to continue improving and optimizing Kimba for sleep,” says Fuxbruner. “Long term, we see Kimba as much more than a sleep company and believe scent can become a powerful interface for improving many aspects of health and well-being.”
