What AudioCardio does
AudioCardio, Inc. is a private digital health company incorporated in California, founded in 2018 by Chris Ellis (CEO) and Sam Kwak (CSO) and headquartered at 1846 9th St Unit 5, Santa Monica, with an operating base in Miami. The company develops and commercializes an evidence-based mobile application, branded AudioCardio, that delivers personalized inaudible sound therapy intended to maintain and strengthen sensorineural hearing and to provide relief from tinnitus. Its core technology, Threshold Sound Conditioning (TSC), is protected by US Patent No. 8,398,563 B2 and works by detecting frequencies at which a user has lost sensitivity, generating targeted inaudible sound stimulation at the just-inaudible threshold to repeatedly activate the corresponding inner-ear cells and reinforce their connections along the auditory pathway. The technology has been evaluated at Oxford Centre for Evidence-Based Medicine evidence level 1a and clinically studied in collaboration with Stanford University, Samsung Medical Center, and Sutter Health's Palo Alto Medical Foundation, with reported outcomes of 10+ decibel hearing improvements in more than 70% of study participants (after three weeks of daily use) and tinnitus severity/frequency reduction in 84% of surveyed tinnitus patients.
The product is delivered as a single mobile application across iOS, Android, and Amazon app stores, with a freemium 14-day trial leading into tiered subscription plans: Basic at $9.99 per month (5 frequency bands, 1 target per ear) and Pro+ at $14.99 per month, $64.99 per six months, or $99.99 per annum (8 frequency bands, 2 simultaneous targets per ear and additional frequency programs). Revenue is generated primarily through these consumer subscriptions, supplemented by gift subscriptions and a nascent corporate/community wellness channel that distributes the product through employers, universities, and hospitals. Co-marketing and referral relationships — including with WeSalute for veterans, Rewiring Tinnitus, Mind Over Meniere's, Pathfinder Labs, and Alex's Lemonade Stand Foundation — support user acquisition across adjacent affinity communities, and the company is piloting clinic-distribution partnerships in Miami with planned expansion across South Florida.
As of March 2026, AudioCardio operates with a team of eight employees and has raised approximately $1.5 million from a private investment group alongside a $174,867 Regulation CF securities offering closed in April 2021. The company has a strategic co-development relationship with Children's Hospital Los Angeles and the FDA-funded Consortium for Technology and Innovation in Pediatrics (CTIP) to extend its technology into pediatric hearing health applications. Pricing, clinical-validation depth, mobile-first distribution, and patent protection form the core of AudioCardio's commercial posture; growth is currently anchored in D2C subscriptions with clinic and B2B channels in early-stage development.
