What Entheo Digital does

Entheo Digital, operating commercially as SoundSelf, is a digital therapeutics company building a voice-activated biofeedback platform for clinical use in psychedelic-assisted therapy and mental health practices. The core product, the SoundSelf System, is a turn-key hardware-plus-software package that captures a user's vocalizations and translates them in real time into synchronized light (via LED glasses), generative music, and vibroacoustic output, producing a closed-loop multisensory experience designed to induce parasympathetic states, modulate Default Mode Network activity, and prime patients for therapeutic work. The platform is positioned as a non-pharmacological adjunct to ketamine infusion therapy, Spravato (esketamine) monitoring, EMDR, and other psychotherapy modalities, with three independent clinical studies (California Institute of Integral Studies, Palm Beach Atlantic University, NeuroMeditation Institute) supporting its claims and EEG-validated brainwave outcomes.

The company's revenue model is hardware-led: the SoundSelf System is sold at $5,500 (with tablet) or $5,000 (A'la Carte), with optional vibroacoustic furniture (mat, sound lounge, zero gravity chair) priced from $2,995 to $9,995 and a recurring $1,500/year SoundSelf Evolution membership. Distribution runs through a direct e-commerce storefront (shop.soundself.com) for individual practitioners and patients, supplemented by enterprise field sales targeting ketamine and Spravato clinics, and conference-driven demand generation at events like Wonderland and Psychedelic Capital. The company is founder-led (CEO Robin Arnott, CSO Sandeep Prakash, PhD), operates under the legal entity New Entheogen Limited, and has raised at least $1M in disclosed funding through 2022.

Revenue model

1. Hardware System Sales (One-Time): SoundSelf System is sold as a one-time hardware purchase (full system at $5,500; A'la Carte at $5,000 without tablet). Optional vibroacoustic furniture accessories are sold separately. This is the primary revenue stream from clinics and practitioners.
2. Subscription / Evolution Membership: The 'One Year of SoundSelf Evolution' membership ($1,500/year) provides ongoing access to the SoundSelf Evolution program, including content updates, new session types, and progressive programming. This represents recurring subscription revenue from existing customers.
3. Financing / Leasing Revenue: Financing options are offered through Brick House Capital, allowing clinics to pay over time rather than upfront. This lowers the purchase barrier and potentially increases deal size while generating financing fee income for the company.

Direct peers

• Muse (Interaxon): Muse is a consumer brain-sensing headband that delivers real-time EEG biofeedback for meditation, sleep, and focus. It is the closest direct competitor to SoundSelf's biofeedback-driven mental wellness positioning, with overlapping customer interest in stress reduction and meditation, though at a lower price point and consumer-led GTM.
• Apollo Neuro: Apollo Neuro is a wearable stress and sleep device that uses gentle vibrations to activate the parasympathetic nervous system. It is comparable to SoundSelf as a non-pharmacological, device-based approach to nervous system regulation, although Apollo focuses on consumer wearables rather than clinical biofeedback.
• Dreem: Dreem is an EEG-based headband for sleep and meditation with real-time biofeedback. It competes directly with SoundSelf in the consumer/clinical biofeedback category for sleep, anxiety, and relaxation, using a different delivery modality (headband EEG vs. voice-activated audiovisual).
• Wave Neuroscience: Wave Neuroscience provides clinical neurofeedback systems targeting mental health conditions including anxiety, depression, and PTSD. It is a direct competitor in the clinical biofeedback/neurofeedback space, sharing SoundSelf's positioning of EEG-measured brainwave modulation as therapeutic, though with a more generalist clinical focus.

Broad incumbents

• Compass Pathways: Compass Pathways is a clinical-stage psychedelic medicine company developing psilocybin therapy for treatment-resistant depression. It is comparable to SoundSelf as a psychedelic-assisted therapy product, although Compass is a pharma/biotech rather than a biofeedback device, and could emerge as a partner or competitor for clinic mindshare.
• MindMed: MindMed is a clinical-stage psychedelic medicine company developing LSD and MDMA-based therapies. It is an established incumbent in the psychedelic medicine space adjacent to SoundSelf's clinic base, comparable as a competitor for therapist/clinic attention and as a potential partner for biofeedback-augmented protocols.
• Headspace Health: Headspace is a leading digital mental wellness platform offering meditation, sleep, and therapy services. It is a broad incumbent in mental health digital therapeutics, comparable to SoundSelf in addressing anxiety and stress, though via subscription app content rather than hardware biofeedback.

Emerging players

• Sens.ai: Sens.ai is a home neurofeedback device combining brain sensing, heart rate variability, and light/sound stimulation for mental wellness. It is an emerging competitor in the at-home biofeedback category, intersecting with SoundSelf's consumer-DTC motion and neurofeedback-driven relaxation use cases.
• Tripp: Tripp is a VR-based mindfulness and mental wellness platform delivering immersive meditation and focus experiences. It is an emerging competitor using VR (a modality SoundSelf explicitly avoids) to induce altered states, and represents an alternative technology path for the same psychedelic-adjacent mental wellness use case.
• Neurable: Neurable integrates EEG-based brain sensing into consumer headphones for focus, productivity, and wellness. It is an emerging player in everyday neurofeedback with comparable signal-processing and clinical-adjacent positioning, offering a different form factor (headphones vs. voice-activated audiovisual) for the same underlying biofeedback category.
