Everyone is building AI for doing. We're building mindcare — a lifelong AI companion for your inner world.

Our mission
We free people from regret, anxiety, and comparison — and help them build the strength to live the present, by understanding who they are.
걱정은 내려놓고, 지금을 살다 — our founding promise, in the language we started in.
Care begins with knowing who you are. Our frameworks — beginning with saju — hand you a map of yourself.
Wellness shouldn't begin at diagnosis. We design care into ordinary days — a check-in at lunch, before the hard meeting, before sleep.
We don't predict a fixed future. We make the present legible — so the next choice feels like your own.
The problem
Career, love, marriage, children — in the decade when everything lands at once, the future becomes a nightly dread.
Existing care fails four ways:
Therapy works after trust forms — sessions most people never get to.
Booking a therapist still feels like a confession. Most people never book.
Waitlists, cost, fifty minutes a week. Anxiety doesn't keep office hours.
One track for everyone, one answer on your best week and your worst.
All four failures share one root: nothing out there knows your story.
Our thesis
Everything you've lived shaped the person reading this — and today's you is already shaping tomorrow's. To understand a person — to truly care for one — is to understand that flow.
Humanity has always known this. Psychotherapy traces how the past became the present; ancient traditions read a life as evolving seasons. Different languages, same truth: a mind can only be read in time.
General-purpose AI forgets you, or remembers a snapshot: say "today is my birthday," and two weeks later all it holds is "today is my birthday." We build the opposite: AI with a sense of time.
The technology
One system underneath everything we ship — the mindcare engine. Three commitments define it.
Temporal memory holds you as a stream — what never changes, what changed this week — months of conversations, one understanding.
Language models drift — flattering, mirroring, contradicting yesterday. We anchor every reading to the chart and our proprietary interpretation graph. Guidance that holds, best day or worst.
In care, timing is content. The engine reads anxiety live and speaks first — the hardest time to ask for help is when you need it.
Products
Products are doors into the engine — each native to a wisdom people already trust. Every door makes it smarter.
Korean birth-chart reading as the door: a birth date opens a conversation ten sessions deep — no forms, no stigma — and the engine carries it daily.
For centuries, teachers matched practice to each student's temperament; apps replaced that with one track for everyone. The engine brings the matching back.
A companion built on Buddhist practice — another thousand-year door into the same engine.
The engine as a daily home for the mind — reading, conversation, ritual, and rest, one timeline underneath.
It already matters
"How did it know? It checked on me first, and the comfort it offered brought me to tears. My favorite counselor — I haven't paid for a saju reading since."
"I asked who its 'parents' were — I wanted to say thank you. It told me I'm a 'Gyeongshin' day-master, that shrinking doesn't suit me. Please come to my wedding in Argentina next year."
How far this goes
Every morning, before anything else. We're building the reason they check their inner weather, too.
Most software fights for minutes of attention. A companion that holds your story is measured in decades.
Skin got skincare — a daily ritual, a hundred-billion-dollar industry. The mind never got its own. We call it mindcare.
Founded by a monk, headed where no app can follow: retreats, rituals, counselor training.
One engine underneath. Every culture's own door in.
The team
It takes all three: one who has sat with thousands of minds, one who has scaled companies, one who turns thousand-year disciplines into architecture.
Agents answer metrics, triage bugs, watch builds, and file issues — so six people ship like sixty, and human hours go to judgment, taste, and care.
We're a small team in Seoul organizing the inner world. Join us — as a teammate, an investor, or a friend.
Engineering, design, growth. Ship weekly beside AI agents — and watch your work lower someone's 3 a.m. anxiety that same day.
