Finnish neurowellness startup Audicin raises $1.9M

The all-female-founded company, backed by Oura Health co-founders and Business Finland, uses brainwave entrainment to support focus, sleep, and recovery via background audio. Its new Sleep Headband targets secure environments where phones are banned.

Audicin, the Finnish neurotechnology company using brainwave entrainment and auditory engineering to support nervous system regulation, has raised $1.9 million in funding.

The round includes private investment, follow-on backing from Petteri Lahtela and Virpi Tuomivaara, the co-founders of Oura Health, the Finnish health tech company behind the Oura Ring, and a grant from Business Finland through its Deep Tech Accelerator programme.

The capital brings total funding to approximately $3 million. The company was founded in 2022 by an all-female team: Laura Avonius (CEO), Victoria Williamson, and Mariana Sousa Aguiar.

Audicin’s technology works through passive background listening rather than active mindfulness exercises. Audio sessions adapted to a user’s physiological signals play in the background while they work, commute, or rest, guiding the nervous system into states associated with focus, stress recovery, or sleep without requiring dedicated attention.

The approach draws on brainwave entrainment, music neuroscience, and auditory engineering. Its SDK, Audicin for Apps, allows third-party digital health, performance, and consumer platforms to integrate the technology passively, triggered by biometric data, time of day, or in-app events, and supports integration with wearables including Oura, Apple Watch, Garmin, and Whoop without additional hardware.

A new product in development takes the company into a more restricted market: a standalone, offline Sleep Headband for environments where mobile devices are not permitted, including healthcare and defence settings.

The device delivers pre-configured recovery programmes based on low-frequency brainwave protocols without requiring a connected phone. Audicin says it is seeing early commercial traction across defence, performance, and wellness sectors, and the funding will support commercialisation of its mobile app, Sleep Headband, and the SDK alongside further product development.
