Everything your company does. Captured. Forever.

Every in-person conversation and phone call. Every ChatGPT and Claude chat, every Claude Code and Codex session. And of course every Slack thread, email, WhatsApp, meeting and doc. From every founder and every employee, in one always-current brain that every agent works from.

Your data can’t leave your infrastructure? It runs in your own cloud →

01 — Why it hasn’t worked

Company brains don’t fail at search. They fail at input.

Problem 1

Never captured.

The real decisions happen in AI chats, calls and hallway conversations. That context stays trapped in one person’s agent, or in their head. Existing tools never see it.

Problem 2

Out of date.

Right on Monday, quietly wrong by Friday. Agents find an old doc or thread and act as if that’s where things stand today.

Company Brain

Captured, always current.

Every conversation, chat and session is captured as it happens, so the newest decision always overrides the old one.

02 — What it captures

Every conversation, every chat, every session. Starting with the ones nobody else ever hears.

  • 01

    In-person conversations

    The café meeting, the hallway decision. Captured on a wearable, announced to everyone in the room.

  • 02

    Phone calls

    Every customer, investor and partner call, transcribed.

  • 03

    AI chats

    Every ChatGPT, Claude and Gemini thread, where the real thinking now happens.

  • 04

    Agent sessions

    Every Claude Code and Codex run: what was asked, what changed and why.

  • And of course

  • Slack

    Every thread and channel.

  • Email

    In, out and cc’d.

  • WhatsApp

    Every customer chat.

  • Meetings

    Full transcripts.

  • Docs

    Every draft and decision.

05 — Where it runs

Your data, your cloud, your keys. Run it wherever your data has to live.

Fastest start

Our cloud

We host it and install it for you by hand within 48 hours. Your company owns the data and can export or delete it at any time.

Reserve or join the waitlist

Founding teams

Your own cloud

The same brain, deployed in your own AWS, GCP or Azure account. We set it up with you. Your data stays inside your VPC, encrypted with keys you hold.

Founding teams

On-prem

For teams that can’t use any cloud. We install it on your own hardware, next to the systems it captures.

Every setup

  • We host it and install it for you, by hand, within 48 hours.
  • Your company owns the data. Export or delete it at any time.
  • Capture is opt-in per company, and every recording is announced.

In your own infrastructure

  • Your own cloud. Deployed in your AWS, GCP or Azure account, inside your VPC.
  • Your keys. Your own encryption keys and your own model provider.
  • On-prem. For teams that can’t use any cloud.

We set up every self-hosted install by hand with the team, within the founding cohort.

06 — Why now

Right now someone at your company is making a decision in a chat with an AI. Nobody else will ever see it. Tomorrow, every agent starts from zero again.

The first truly agent-native companies won’t have better models. They’ll have total memory.

We install every team by hand, so each founding cohort is limited to 6 companies. Reserve a place and we start within 48 hours.

  • Reserve

08 — Questions

The honest answers.

Who owns the data, and who can see it?

Your company owns it and can export or delete it at any time. Everyone in the company can see everything, founders included. There are no manager-only dashboards and no hidden views.

Capture is set up per company and needs everyone’s knowledge and agreement, so it’s built for teams that opt in together. Every recording is announced. We don’t analyze emotions or tone.

Can we run it in our own cloud or on-prem?

Yes. We host it for you, or we set it up in your own cloud account or on your own servers, under your own keys. Tell us where it should run.

Is it just a notetaker?

No. Notetakers capture meetings. Company Brain captures the conversations, phone calls, AI chats and agent sessions where the work now happens, then everything around them: threads, email, meetings and docs.

What if we change our minds?

The $100 deposit is fully refundable anytime before your install starts. Email us and it’s back on your card within 5 business days. If we can’t start your install within 30 days, we refund it automatically. Terms

Do we have to learn a new tool?

No. There is nothing new to open. We install it into the agents and tools you already use, within 48 hours.
