SHIN4NY

What SHIN4NY does

SHIN4NY is a Japanese voice-AI startup founded in December 2022 by Haruka Kudo (CEO) and Kanji Okazaki (CFO & Engineer), with engineering led by CTO Masao Tsutsui. Headquartered in Odawara, Kanagawa Prefecture, with development operations in Utsunomiya, Tochigi Prefecture, the company develops a family of products built around its proprietary Heart Voice audio parsing engine. That engine extracts emotional, stress, drowsiness, and excitement signals from speech characteristics - voice tremor, modulation, tempo, and speech flow - without requiring semantic content of speech. Flagship products include Heart Voice (a consumer self-mental-care app with 7-day free trial), Sleepy Meter (predictive drowsiness detection for drivers and industrial users), Voltage Index (registered trademark - real-time crowd-excitement visualization deployed at J-League, B-League, and e-sports venues), Harmony Talk (speech-impression feedback), and Care Cube, a mental-check robot co-developed with Sound & Vision Technologies that combines Heart Voice with facial recognition across Japanese, English, and French.

The technology layer is proprietary: SHIN4NY runs an API for developers, integrates its engine into partner terminals, and conducts applied research with Saitama University. The commercial strategy is hybrid B2B/B2C. B2B revenue (enterprise subscriptions and pilots) flows through direct sales into sports teams (Tochigi SC, Utsunomiya Brex, Tokyo Verdy, e-sports team Meteor), logistics operators (Ohkawara Transport via Sleepy Meter), and government/municipal pilots (Metropolitan Expressway Corporation at Daikoku PA, Utsunomiya City, Fukushima Prefecture wildlife-detection programs). B2C revenue comes from Heart Voice subscriptions converted from the free trial. The company also earns professional services revenue from government-funded accelerator and demonstration contracts (Fukushima Tech Create, Utsunomiya Accelerator, Tochigi Startup Accelerator, KISTEC) and runs a recurring e-sports tournament platform (SHIN4NY CUP) to showcase Voltage Index.

The company remains a small founder-controlled team without disclosed external equity funding. Distribution leverages high-visibility public channels - EXPO 2025 Osaka-Kansai, iREX 2025, SusHi Tech Tokyo, and earned media (Toyo Keizai) - alongside a deep network of Japanese regional innovation programs that subsidise pilot deployments and produce commercial references. Revenue is not publicly disclosed and most enterprise engagements visible in the input data are at pilot or demonstration scale rather than large recurring contracts.

Direct peers

• Beyond Verbal: Beyond Verbal developed voice-based emotion and health analytics from vocal intonation. It is an early-mover peer in paralinguistic voice analysis with similar technology roots to SHIN4NY's Heart Voice engine.
• Behavioral Signals: Behavioral Signals develops OliverAPI, a voice emotion AI platform for call center agent-assist and conversational analytics. Comparable to SHIN4NY's voice-feature extraction engine applied to real-time enterprise voice streams.
• Kintsugi: Kintsugi applies voice biomarker AI to detect depression and anxiety via a 20-second voice sample, sold into telehealth and benefits platforms. Directly comparable to SHIN4NY's Heart Voice self-mental-care app in modality, customer segment, and commercial model.
• Sonde Health: Sonde Health is a voice-based digital health company that detects mental and respiratory conditions from voice biomarkers. It overlaps directly with SHIN4NY's Heart Voice and Care Cube mental-health positioning, serving health plans, pharma, and employers with clinically validated voice analysis.
• Hume AI: Hume AI builds foundation models for voice emotion, expression, and speech analysis, offering an API that infers emotional states from voice in real time. It is the closest direct competitor to SHIN4NY's Heart Voice / Sleepy Meter engine, targeting similar developer and enterprise use cases (wellness, contact center, healthcare).
• Ellipsis Health: Ellipsis Health uses voice biomarker AI to detect anxiety and depression for healthcare payors and providers. Direct overlap with SHIN4NY's mental-health voice analysis products (Heart Voice, Care Cube), though Ellipsis is more clinically entrenched in US health systems.

Broad incumbents

• Affectiva (Smart Eye): Affectiva (now part of Smart Eye) provides emotion-sensing AI across facial and vocal cues for automotive, retail, and research applications. Broader incumbent than SHIN4NY, with established automotive DMS deployments that overlap with Sleepy Meter's driver-drowsiness use case.
• Catapult Sports: Catapult is an established sports-performance analytics company (GPS wearables, athlete monitoring) that sells to professional teams and leagues globally. Comparable to SHIN4NY's athletic mental-performance engagements (e.g., TN45 Racing) and Voltage Index venue deployments, though with a much broader product portfolio.
• Seeing Machines: Seeing Machines is a leader in camera-based driver monitoring systems deployed across automotive OEMs. Relevant comparable to SHIN4NY's Sleepy Meter for driver safety, though the company leads with vision rather than voice — a useful benchmark on the drowsiness-monitoring opportunity.

Emerging players

• Realeyes: Realeyes applies emotion AI to attention and sentiment measurement for digital advertising, market research, and sports sponsorship analytics. Overlaps with SHIN4NY's Voltage Index sports/event enthusiasm measurement use case, particularly in quantifying crowd response.
