TL;DR

• Sleep tech startup Kimba launched with $6.5 million in funding led by Selva Ventures, backers of brands like Grüns and OneSkin.
• The device uses AI and biometric data (including from WHOOP, Oura, Apple Watch, Fitbit, and Garmin) to deliver personalized scent cues that actively improve sleep, not just track it.
• Pre-orders are open now at kimba.ai for $299, including the device, software, and a 6-month supply of scents.

Sleep tracking has become table stakes.

Nearly every wearable on the market, from WHOOP, to Oura, Apple Watch, Fitbit, Garmin can tell you how you slept last night. What none of them can do is actually change the outcome.

That’s the gap Kimba says it’s built to fill.

The sleep technology startup launched today with a $6.5 million funding round led by Selva Ventures, a consumer health and wellness investor with a track record that includes Grüns and OneSkin. Kimba’s pitch is straightforward on its face but ambitious in execution. Kimba uses scent to actively improve sleep quality in real time, rather than just report on it the next morning.

How It Works

Kimba pairs a bedside device with proprietary water-based, plant-derived scent formulations tailored to an individual’s sleep patterns. Throughout the night, the system tracks breathing, movement, heart rate variability, and stress signals; either through its own built-in sensors or by pulling data from wearables you’re already using, which for us is pure joy. An AI model processes that data in real time and triggers precisely timed scent releases designed to support deeper, more continuous rest.

The science behind the approach centers on the olfactory pathway, which the company describes as the only sensory channel that can influence brain activity during sleep without waking the person up. The idea is to nudge the body toward better sleep stages and recovery without the side effects associated with sleep aids—no pills, no grogginess, no dependency.

The Founder’s Story

Kimba was founded by Ben Fuxbruner, a former special forces commander whose own struggle with PTSD and chronic insomnia following a near-death injury became the catalyst for the company. After searching for solutions that didn’t exist, he set out to build one.

“Kimba was built on a simple but powerful idea that sleep shouldn’t just be measured, it should be improved,” Fuxbruner said. “We’re introducing a fundamentally new approach that uses scent to work with the brain during sleep, helping people achieve deeper, more restorative rest without drugs or disruption. For me, it was life-changing.”

Early Clinical Validation

Kimba isn’t launching on vibes or hope alone.

In a study of 50 participants over 48 nights, conducted with olfactory neuroscience expert Dr. Anat Arzi, the company reported meaningful improvements in both sleep quality and cognitive performance. Two additional clinical studies are now underway under the guidance of sleep researcher Professor Peretz Lavie—one using polysomnography (PSG) testing to evaluate physiological outcomes, and another examining Kimba’s potential impact on sleep and recovery for people dealing with PTSD.

“The influence of sensory input during sleep is significant,” Dr. Arzi said. “Olfactory stimulation is uniquely beneficial for this because it can influence brain activity without waking the individual. By aligning scent delivery with specific breathing patterns, sleep stages and physiological signals, this approach has the potential to meaningfully improve sleep quality.”

Pricing and Availability

Kimba is now available for pre-order at kimba.ai.

The $299 package includes the device, the software platform, and a six-month supply of personalized scents, along with a six-month membership.

But you will have to wait for better sleep, as this is pre-order only to start.

Why It Matters

We haven’t tested Kimba ourselves, so we can’t vouch for the real-world results, and for us, pre-order products always come with a “wait and see” asterisk. But the underlying premise is hard to argue with. Sleep is consistently one of the highest-leverage things any of us can do for performance, recovery, and overall health, and most of the tech in this space has been built to measure that rather than improve it.

Strip away the AI buzzwords, and scent-based sleep intervention is a genuinely interesting idea on its own.

Add in the founder’s personal story (love!) and the solution he set out to build, plus the fact that Kimba is low-friction, drug-free, and grounded in legitimate neuroscience around the olfactory system. Factor in Selva Ventures’ track record with brands like Grüns and OneSkin, and there’s reason to think Kimba is worth a look, even if you have to wait a bit to try it.
