How it works Intelligence Core Workflow Engine Pricing Work About Book a walkthrough

Run your business on AI. Keep your hands on the wheel.

We build the system that lets a business run on AI without anyone having to become an AI person. A brain that knows your company. A loop that turns every ask into finished work. A person on the approve button.

The loop

Every ask becomes a task. Every task gets done.

This is the product, drawn. A Slack message, a voice memo on a walk, a 38-minute call: each one turns into a proposal with real context, waits for a yes, and then an agent does the work and reports back.

1 · Capture. An ask arrives the way asks do.

Why this, why now

The problem is not access to AI. It is that nobody has time to use it well.

01

Everyone has a chat window. Almost nobody has a system.

Prompts live in people's heads. Context gets retyped every time. Nothing is reviewed. The output sounds like a robot because it has never read your brand guide, your pricing, or last quarter's decisions.

Buying more seats does not fix this. A system does.

02

What a business actually needs is three things.

A brain: your real knowledge, voice, and facts in a form a model can use. A loop: asks come in, work gets proposed, a person approves, agents execute, results come back. And a line it will not cross: nothing published, sent, or deleted without someone saying yes.

03

We know, because we run on it.

Katsura runs on Katsura. A voice memo on a morning walk is projects and tasks with full client context by the time we are home, waiting for approval, ready for an agent. Screenshots of Slack asks become tasks. Calls become the three action items that are actually ours.

The whole loop, step by step

What we build

A brain, a loop, and a line.

01

the brainIntelligence Core

Your brand voice, approved facts, offers, audiences, playbooks, and proof assets, ingested from everything you have ever published. Delivered as a connector into Claude so every seat has the company brain. Drafts get checked against the guides before a person sees them.

02

the loopWorkflow Engine

One recurring ask type, end to end: calls that file their own action items, screenshots and forwards that become tasks with context attached, approved tasks handed to agents and returned for review. The loop above, pointed at one part of your business.

03

the lineReview-first, by design

Everything is a proposal until a person approves it. Every proposal cites its source: the memo, the screenshot, the email. This is the answer to "what if it goes rogue," and it is architecture, not a policy. For mail, calendar, HR, and finance, we can run the model on hardware that never leaves your building.

Proof

Built once for us. Built once for a client. Both running today.

clientnational staffing companymarketing team

A company brain for a marketing team of many.

Brand voice, approved stats, service lines, audience playbooks, the full resource library, success stories, and a client quote bank, all behind one connector. Every draft gets a buddy review against the guides before a human sees it. A Studio writes branded resources, email sequences, and ad scripts from the same source, with per-person budgets so the bill stays boring.

The operating system we run the company on.

Voice memos, screenshots, meeting audio, and a project tracker, all feeding one Inbox. Native apps with offline queues and sync that does not lose things. A one-button handoff from an approved task to a coding agent, with the result reported back into the task for review.

  • ✓
    Review-first by architecture.Nothing acts without approval. Every proposal shows where it came from.
  • ✓
    Private where it matters.Mail, calendar, and anything regulated can run on a model that never leaves your machine.
  • ✓
    Brand-literate.Katsura is a creative agency first. The output sounds like you because the system has read everything you have published.
