What IGSA does

AI-native transformation

With AI as the premise, what a business can be changes. We rebuild operations, products, and how the business is run to be AI-native, working alongside you to drive change that translates directly into business outcomes.

Healthcare

Voice and biosignal AI that catches brain and mental change early and turns it into the small daily actions that keep people well — not just awareness, but the ability to stay healthy.

Technology provision

The voice biomarkers and biosignal analysis we have honed in-house, deployed into the world together with pharma, clinics, and partners.

What we offer

FOCUSWhere we put our weight

Operations and engineering, made AI-native.

IGSA X is a hands-on engagement that redesigns both the operations stack and the engineering stack with AI as the premise. We own it end-to-end — from requirements through fast implementation with coding-AI-driven development.

Not a business-transformation consultancy, not a software house. We evolve operations and engineering in lockstep, and stay through internalization — so when the project ends, what's left inside the client is an AI-native organization and the processes to run it.

HEALTHCAREHealthcare

Supporting brain and mental health

Hanashitene

A daily habit for brain health. Two minutes of voice each day visualizes cognitive state and suggests small actions to keep it sharp. Built for people in their 50s–70s, with self-check designed into ordinary life.

Hanashitene for Care

For care providers — ongoing monitoring of cognitive and mental change, with a dashboard that surfaces per-resident trends. A field tool for catching early shifts and shaping personalized care plans.

Hanashitene for Municipalities

For local governments — voice-based brain-health checks embedded in dementia-prevention and healthy-aging programs. We co-design resident-facing touchpoints and stay through to program evaluation.

Koe-memo

Voice memo × healthcare. One tap, one short note — AI structures it, and quietly tracks shifts in mood and fatigue underneath. Useful for personal self-care and as a lightweight wellness layer for organizations.

TECHNOLOGYTechnology provision

R&D delivered into the world

Voice Biomarkers

Custom voice-based indicators for mental health, cognition, fatigue, and emotion — extending into metabolic, respiratory, and cardiovascular signals. Delivered to pharma, clinics, and healthcare apps via joint research or technology provision.

Biosignal Analysis

End-to-end AI support for EEG, EMG, EOG, ECG, and respiratory signals — preprocessing and cleaning through modeling and real-time inference pipelines.

Sugutori

Image-AI for second-hand operations — grading, model-number ID, tagging, and listing. Compact-model technology keeps running costs low for reuse, recycling, and leasing businesses.
