Building systems that work together.
We develop intelligent systems that cooperate with people and with one another. Sathi brings that work into everyday life, connecting apps, services and devices in one continuous experience across home and work.*
Sathi Systems is based in Japan, working with AI Sathi’s engineering team in Kathmandu, Nepal.
- Product
- Sathi is live with its first families.
- Engineering
- One system, four languages, built across Japan and Nepal.
- Stage
- Beta access, with product development informed by everyday use.
Models change. The relationship should not.
AI capability will keep moving between providers, devices and forms. We are building the layer that keeps a person's identity, memory, permissions and continuity intact while everything underneath improves.*
Work with usStart with one useful workflow
We help define a practical first use case, review the systems involved and scope a pilot around a measurable outcome. Data access, responsibilities and delivery terms are agreed before work begins.

Where we workBuilt across Japan and Nepal
Two homes, two strengths, one system.
Japan — Sathi Systems
Our corporate and commercial base in Yokosuka, Kanagawa, supporting customer relationships, partnerships and operations in Japan.
Nepal — AI Sathi
The engineering and product home. AI Sathi in Kathmandu builds the backend, tests the product in the languages and daily life it is built for, and is where the engineering team grows.
The word sāthī means companion — one word shared across Nepali, Hindi, Bengali and Urdu.
Principles, in briefWhat we believe
Individuals are not the product.
No advertising, no engagement optimization, personal data never sold. Access is free during today’s beta; future hosted plans will publish finite cloud allowances.
Designed to keep memory and permissions through change.
Models and agent runtimes sit behind one interface, designed to carry a person's memory and permissions across engine changes.*
