Studio profile

A studio that builds business systems with AI

Senior engineers and an AI agent team own everything from requirements to deployment and operation.

We designed and run AI agentic workflows in our own company first,
and deliver what we have actually built to our clients.

Running now

These are the systems running this company right now.

How one task flows · replying to a customer inquiry

  1. Input

    Inquiry arrives

    Inquiries from the website, email and marketplaces land in one place.

  2. AI judgment

    Read and classify

    AI scopes the request, classifies the work and picks the matching service.

  3. Result

    Draft reply

    A draft reply with the quote scope and next steps is prepared.

  4. Approval gate

    Reviewed, then sent

    Anything going to a customer is sent only after the responsible engineer reviews and approves it. Nothing is sent automatically.

How we build

Development runs on five layers of AI systems.

The AI model is a replaceable part; quality and safety are held by the system around it. We build client systems on the same system that runs our company every day.

  1. L1

    Execution

    Role-specific AI agents take the work. The agent that builds and the agent that reviews are kept separate.

  2. L2

    Context

    Decisions, task records and official technical docs are kept, and each task loads only the rules and material it needs. Work resumes from the record even if a session breaks.

  3. L3

    Safety

    Checks run before and after every tool call, and irreversible actions such as sending, payments and deployment run only when they match what a human approved.

  4. L4

    Evaluation

    Results are measured on test data never used in development, and a reviewer agent with no task context looks for gaps separately.

  5. L5

    Operations

    Unattended jobs and monitors run continuously and record failures, and the next task reads those records first.

Ownership

One owner from design to handover.

The engineer who designs the system owns requirements, development and handover end to end, so your point of contact never changes. That engineer brings hands-on operations and automation experience from financial investment and fintech, two of Korea's most heavily regulated industries.

Repetitive work is split across the five AI layers, while judgment and accountability stay with people. Reusing our own data and code assets shortens the time from kickoff to a first working version.
