Wellness tools typically demand something most people cannot spare: time, attention, and ideal conditions. Audicin is building around that gap. The Finnish neurotech startup has raised $1.9 million (€1.6 million) to scale a system that passively regulates the nervous system in the background of everyday life, without asking users to pause anything.

The round includes private investors and follow-on participation from Oura ring co-founder Petteri Lahtela and Virpi Tuomivaara, who also backed the company’s earlier pre-seed.

Alongside the equity raise, Audicin has received support from Business Finland‘s selective Deep Tech Accelerator, a phased non-dilutive programme tied to technical and commercial milestones. Combined with previous rounds, total funding now stands at approximately $3 million.

The capital will accelerate the commercialisation of Audicin’s app and Sleep Headband, and drive the rollout of Audicin for Apps: a lightweight SDK that allows digital health, performance, and consumer platforms to embed real-time nervous-system regulation directly into their user experiences, without requiring any new hardware.

Turning sound into a functional interface

Founded in 2022 by Laura Avonius and Dr Victoria Williamson, Audicin grew out of Avonius’ own recovery from complex PTSD. That experience exposed a fundamental design flaw in most wellness tools: they are built for ideal conditions, requiring time and calm that the people who need them most rarely have.

“The primary motivation was the feeling that most wellness and recovery tools were built for ideal conditions, not real life. I started Audicin during my own recovery from complex PTSD, and that period made it very clear to me how inadequate it is to ask people who are already overwhelmed, dysregulated, or exhausted to simply “take a moment” and somehow fix themselves,” Avonius tells TFN.

Avonius, also known as musician GEA, serves as CEO. Dr Williamson, a music psychologist and neuroscientist whose research focuses on how sound influences the brain and nervous system, leads research and product development as co-founder and Chief Scientist.

The company is supported by a Medical Advisory Board that includes Dr Hannu Kinnunen, former Chief Scientific Officer at Oura; Joel Naukkarinen, MD, an eight-time world champion; and Dr Jenni Hyysalo.

Audicin’s platform combines brainwave entrainment, auditory engineering, and music neuroscience. It delivers sessions through psychoacoustic protocols that blend original compositions, precision-engineered binaural frequencies, and immersive spatial sound. Sessions are designed to run passively, triggered by biometric signals, time of day, or in-app events, without interrupting the user’s activity.

The system integrates with leading wearables, including Oura, Apple Watch, Garmin, and Whoop, using physiological data to dynamically adapt sessions to the user’s current state.

For environments where phones and Bluetooth are restricted, including healthcare and defence settings, the company is piloting a standalone offline Sleep Headband with a pre-installed eight-hour recovery program built around a 1Hz delta protocol associated with deep sleep.

Traction without paid acquisition

Since launching Audicin 2.0 in late 2025, the company has grown entirely through organic discovery. Users have increased by 40% in 12 weeks, iOS revenue has more than doubled over 90 days, and users average 5.5 sessions per week. The subscription renewal rate stands at 69%, with strong week-one retention across cohorts.

Petteri Lahtela, co-founder of the Oura ring, frames the investment thesis simply: ““Audicin doesn’t depend on user effort or ideal conditions. It functions more like infrastructure: something that can operate during work, rest, and in restricted environments. That’s fundamentally different from tools that require carving out time for wellness, and it’s why we see strong potential both in enterprise deployments and through Audicin for Apps as platforms begin integrating real-time nervous system support directly into their products.”

Beyond the consumer app, Audicin reports an $8 million sales pipeline spanning defence, athletic performance, and wellness clinics. Allied Federal Solutions, which works with the US defence and veterans communities, is among its named partners.

“Over the next three to five years, our goal is to establish Audicin as the category-defining company in neuroadaptive sleep and recovery, as a core human-performance infrastructure for people operating in the most demanding conditions, starting with defence and elite sport and expanding to other high-reliability professions,” Avonius concludes.
