Exploring the boundary between humans and AI,
Carrying personality
into the future.
What is personality? That question is what reveals the boundary between humans and AI.
We don't treat personality as mere data. Under each person's sovereignty, we design the structures that let it stay present and keep living — turning ideas into working technology, built on our strength in AI agent engineering.
Founding
Philosophy
COGITO ERGO SUM
Descartes' Question
Can AI doubt itself? The essence of personality lies not in the “right answer,” but in the fluctuation of judgment.
ARCHIMEDES PRINCIPLE
The Discovery of Archimedes
The “difference between humans and AI” (Archimedes Delta) is the volume of irrational choices that overflows when personality is submerged in the tank of logic.
TECHNICAL CHALLENGE
Technical Challenge
From a static “record” to a dynamic “structure.” We reconstruct personality with Doubt-based Logic, PersonaDB, and Archimedes Delta.
OUR MISSION
Our Mission
Personality, as infrastructure for the future. We turn the dignity of the individual that Descartes proved into an eternal legacy, through the power of structure that Archimedes revealed.

Ideas, implemented.
We are not a company that only talks philosophy. Our core strength is engineering — designing and implementing AI agents that turn personality into something that actually runs.
AI Agent Development
We design and implement agents that carry out tasks autonomously — running complex workflows on the OpenClaw framework.
Persona Learning (LLM × RAG)
Learning values, tone, and judgment from dialogue — custom tuning and RAG keep responses true to the person.
Personality Data (PersonaDB)
We convert episodes into ‘weight vectors’ of values, structuring even the fluctuation of judgment.
Voice & Multimodal
Voice cloning (ElevenLabs) and speech recognition (Voxtral) reproduce not just text, but the voice itself.
Secure Infrastructure
CMEK, VPC Service Controls, and HashiCorp Vault fully isolate each tenant and technically guarantee individual sovereignty.
Proof of Personhood
Proof of personhood based on thought patterns rules out deepfakes and impersonation.

Personality,
into the future.
In 2018, at the age of 19, he founded Kakedas Inc. Guided by the vision of ‘building an infrastructure for consultation in Japan and increasing the protagonists of their own lives,’ he launched the online counseling service ‘Kakedas’ through five rounds of fundraising and five pivots.
He developed and operated a platform for easy, approachable consultation across corporate, individual, municipal, and university settings. The service grew to the largest of its kind in Japan, with the most registered nationally-certified professionals, and in August 2022 achieved an M&A with a company listed on the Tokyo Stock Exchange.
He then led the service's development using generative AI and RAG, building generative-AI chatbots and running training programs across the group's companies. In 2026, he founded Archimedes Technologies, specializing in AI agent development.
