THE COMPANY

Built inside a factory, not a pitch deck.

PurpleBrain began inside a U.S. industrial equipment manufacturer with a hundred-year-old problem: the answers lived in 20,000 documents and a handful of heads. Cutsheets in Excel, drawings in a vault, judgment in the hallway conversations of engineers approaching retirement.

We built the system that turned that into a knowledge layer engineers actually trust — every answer cited to the drawing it came from, every new fact reviewed by a person before it becomes truth. It runs in production today.

Then we did what engineers do: we generalized it. PurpleBrain is the spin-out — the same infrastructure, pointed at any organization whose knowledge is scattered across documents, systems, and people.

How we work

PurpleBrain is deliberately small and senior. The people who built the production system are the people on your engagement — no handoffs, no bench.

WHAT WE BELIEVE

Four rules we don't break.

Every answer needs a receipt.
A person signs off before anything becomes truth.
AI that can't say "I don't know" can't be trusted with anything else.
Your knowledge should run on your infrastructure.
GET STARTED

Show us your messiest documents.

Bring your hardest document set to a working session. We'll show you what a knowledge layer that cites its sources can find in it.

Your message goes to a person who can act on it — not a queue, not a list. We don't publish or share your contact details.
