Authority AI · Company Brain for YC Startups

Every decisiondeserves thefullpicture.

Your company already knows the answer. It's in Slack, Notion, Stripe, and Linear - disconnected, delayed, and invisible at the moment a decision needs to be made. Authority AI changes that.

The Three Decision Killers

  2. Killer 02
    Incorrect Knowledge
    Decisions made on stale data
  3. Killer 03
    Disconnected Knowledge
    Decisions made in the dark

The answer your company needed already existed somewhere inside it. The problem was never capability. It was always the flow of knowledge to the moment of decision.

The Decision Problem

§01

Three killers.One structuralcause.

These are not people problems. They are not process problems. They are infrastructure problems - and infrastructure problems have infrastructure solutions.

  1. I.

    Delayed Knowledge

    Decisions made too late

    The right information existed. It arrived after the window closed. The deal slipped. The hire was wrong. The churn was preventable.

    What it costs you · A sales insight that reaches the team three weeks late. A customer signal buried in a Gong transcript. A competitive move your team would have countered - if they had known in time. At a YC startup, every week of delay compounds.

  2. II.

    Incorrect Knowledge

    Decisions made on stale data

    Outdated pricing in a proposal. A conflicting figure from an old deck. Your team moves with confidence - on information that was wrong last quarter.

    What it costs you · Incorrect knowledge is invisible until it surfaces as a mistake. By then, the deal is lost, the investor is confused, or the strategy has been set in the wrong direction for a quarter. It rarely looks like an information problem. It looks like execution.

  3. III.

    Disconnected Knowledge

    Decisions made in the dark

    The answer was in the company. Sales knew it. A Notion page had it. A former employee carried it. It never reached the person deciding.

    What it costs you · Questions answered twice. Strategies repeated. Lessons never transferred. At a 15-person startup, when one person leaves, 10% of institutional memory walks out with them. Authority AI makes that impossible.

The Larger Vision

§04

We are buildingthe world's decisioninfrastructure.

We start with the company brain. The larger vision is bigger. Every human endeavor - companies, universities, hospitals, governments, individuals - makes decisions. Almost none of them have the full picture at the moment it matters.

Google organized the world's information. Authority AI is building the infrastructure that turns information into decisions - structured, sourced, permissioned, and available to anyone who needs to act.

  1. Principle I

    Decisions delayed are opportunities destroyed

    Speed of knowledge flow is speed of organizational response. Every hour between an insight and a decision is an hour your competitor may not have. Authority AI eliminates the latency between what your company knows and what it acts on.

    The organizations that act on the right information first define the market - not the ones with the biggest teams.
  2. Principle II

    One correction should make the whole company smarter

    When your best operator catches a knowledge error, that fix should cascade across the entire organization immediately - not remain locked in one person's head until they leave. Authority AI converts individual corrections into company-wide upgrades.

    The company that learns faster than its competitors has found the only sustainable advantage.
  3. Principle III

    Institutional memory is a compounding asset

    Your competitors are betting their people will remember what matters. You will build a system that cannot forget. That is not a technology difference - it is a structural advantage that widens every quarter Authority AI runs.

    The companies that institutionalize what they learn will outcompete those that rely on individuals to remember.

Common Questions

§05

Questionswe get asked.

If your question is not here, email the founder directly. We answer every email.

What exactly is a company brain?
A company brain is the decision-making infrastructure that connects all of your knowledge sources - Slack, Notion, Stripe, Linear, HubSpot - and makes that knowledge instantly accessible to anyone who needs to decide. Instead of searching across five tools, you ask one question in Slack and get a sourced, accurate answer in seconds. It is not a search engine. It is a structured decision layer built on your company's actual data.
How is this different from Notion AI or Glean?
Notion AI only knows what is in Notion. Glean requires a 100-seat minimum and costs over $60,000 per year - designed for enterprises, not startups. Authority AI connects all ten systems your company uses, applies a schema-first architecture that knows which source to trust when they conflict, and is priced for startups from day one.
Why only YC companies for the beta?
YC companies share a specific tool stack - Slack, Notion, Stripe, Linear, HubSpot - and a specific pace of decision-making. Building for this cohort first lets us go deep on the exact integrations and use cases that matter, rather than building shallow support for hundreds of tools.
What does free actually mean for the first ten companies?
Free means $0. No credit card. No trial period that converts. The first ten companies get full access - all ten integrations, unlimited questions - for the duration of the beta. In exchange, we ask for direct feedback and one conversation per month with the founder.
