Y Combinator Request for Startups

Your team knows everything.
Your company remembers nothing.

Critical knowledge lives in Slack threads, old docs, and the heads of people who might leave tomorrow. CompanyBrain captures it all, structures it, and makes it instantly accessible.

The Problem

Knowledge scattered.
Context lost.
Answers buried.

Every engineering team suffers from this. The knowledge exists — it's just in the worst possible places.

💬

"Ask Raj, he knows."

Critical processes live in one person's head. When they're on vacation — or leave — the knowledge goes with them. No documentation, no backup.

🔍

"I know we solved this before..."

The answer exists in a Slack thread from 8 months ago, or a Google Doc no one can find, or a commit message buried in git history.

📝

"The docs are outdated."

Documentation was written once and never updated. New engineers follow stale guides. Everyone knows the docs are wrong — nobody fixes them.

"I've been onboarding for 3 months."

New team members take months to become productive because there's no single source of truth for how things actually work here.

How CompanyBrain works

Not another doc search tool. A system that understands, structures, and preserves how your team actually operates.

01

Ingest everything

Connect your existing sources. We parse, chunk, and understand the content — not just store it.

PDFs & Docs GitHub Slack Interviews
02

Extract & structure

AI identifies processes, rules, ownership, decisions, and tools. Builds a living knowledge map automatically.

Processes Ownership Decisions Rules
03

Ask & act

Your team asks questions in plain English. Gets grounded answers with citations, confidence, and source links.

Citations Confidence Sources
What Makes Us Different

Two things no doc-search tool does.

Everyone can build RAG over documents. Our moat is deeper.

1
Knowledge Extraction

We don't just store documents. We understand them.

Every document is analyzed by AI to extract structured knowledge: processes, rules, who owns what, past decisions, tools used. This builds a living map of how your company works — not just a pile of embeddings.

2
Tribal Knowledge Capture

We pull knowledge out of people's heads before they leave.

5 structured interview questions, designed for engineers. The AI converts their spoken answers into clean, searchable process documents. The stuff that would be lost forever — captured and preserved.

Use Cases

Questions that waste
hours every week.

These are real questions your team asks every day. Right now they take hours. With CompanyBrain, they take seconds.

"

How does deployment work? What's the full checklist?

"

Who owns the auth service? Who should I talk to?

"

We had this exact bug before. How did we fix it last time?

"

Why was this architecture chosen? What were the tradeoffs?

"

What's the onboarding process for new engineers?

"

What happens when the payment service goes down at 2am?

The biggest blocker to AI automation is no longer the models. Now the blocker is the domain knowledge. Every company in the world is going to need a company brain.
