Value proposition

Kagami AI analyzes video and audio from in-person settings to quantify non-verbal cues (facial expressions, voice tone, pauses, concentration levels, excitement, satisfaction) — turning the "feel of a room" into actionable data without requiring participants to wear any devices.

Products and solutions

Kagami AI (カガミAI) — SaaS platform that analyzes video/audio from in-person and hybrid settings to measure: excitement/engagement time-series, concentration levels, disengagement signals, Q&A quality, satisfaction changes, and generates improvement reports with consulting. Pricing: ¥33,000/month (One-shot), ¥55,000/month (Standard), ¥99,000/month (Premium), plus custom enterprise plans.

Unique value

The only AI tool that captures non-verbal reaction data from physical spaces (not just online) without wearable devices, enabling data-driven improvement of in-person experiences across beauty salons, education, corporate training, and events.

Target customer

Beauty salon owners, corporate training managers, HR departments, event organizers, educators, fitness studios, retail store managers — any business where in-person human interaction quality directly impacts outcomes.

Industries served

Beauty & Salon, Education & Training, Corporate Events & Conferences, Retail & Customer Service, Fitness & Wellness, Tourism

Technology advantage

Computer vision + audio analysis AI trained on non-verbal cues (facial expressions, voice tone, timing, group dynamics); SaaS + consulting hybrid model; KOSEN/spinout engineering DNA; first-mover in Japan's beauty salon vertical for non-verbal analytics

How they differentiate

Unlike online-only engagement analytics or wearable-based biometric tools, Kagami AI works in physical spaces using existing cameras, requires no participant devices, and combines AI video/audio analysis with consulting services to deliver actionable improvement reports. The focus on non-verbal cues in real-world settings (vs. digital click/scroll data) is a unique positioning.

Market positioning

Early-stage Japanese startup pioneering non-verbal reaction analytics for physical spaces, initially targeting beauty salons as beachhead vertical, with expansion into education, corporate training, events, and retail. Competes in the broader emotion AI / engagement analytics space but differentiated by focus on in-person (not digital) environments and no-wearable approach.

Geographic focus

Japan (primary), with potential expansion to other Asian markets
