// The Proof Engine

Nobody reads your deck. Be honest, you don't read theirs either.

So this doesn't send decks. For every named account it researches the business, builds a working proof of it (their numbers, their products, running, in their own brand), mails it to their desk with a code they can scan, then reacts to what they do with it. They don't read about the value. They hold it.

It cost $1.12 to put there. Your last click cost $14 and got ignored.

The mid-cart logout drives the lost orders the founder is publicly worried about. Defensible from the review volume, not invented.

Dana, this page is about Brokaw Supply, not about me.
I spent an hour in your reviews. Here is the $48,000 problem hiding in them, and what it looks like solved. Move the sliders. If I'm wrong, the math will say so.

Built for Brokaw Supply by Jeff Brokaw, Certified Chief AI Officer.
Clean white, their logo, their palette (navy / sky / amber), their font. Deliberately nothing like this dark site, because the page is theirs. Demo uses your browser voice; production ships a ~30s ElevenLabs note in Jeff's voice.
DIRECT MAIL

And mails it to their desk

REJECTEDHi Dana, hope you're well! We help companies like Brokaw Supply Co. grow. Would love to connect.

Dana, I went through Brokaw Supply's reviews last week. The same complaint shows up 14 times since March, and by my math it's costing you about $48,000 a month. I didn't write you a pitch. I built you something: unignorable.jeffbrokaw.com/p/brokaw-supply It's your numbers, your products, working. Three minutes. If the $48,000 is wrong, the model on the page will prove it.
No API send. Jeff reads, edits, sends by hand. That gate is in the architecture, on purpose.

This is a demo of a machine that is real.

The prospects above are synthetic, so nothing here pitches a real company. The pipeline underneath is not a mockup: an n8n workflow builds and deploys each white, prospect-branded proof page on the fly, Clay scores and gates, Opus 4.8 writes the dossier, Stannp mails the dynamic QR, and a real branching decision tree writes deal stages into HubSpot and alerts a human only at the moments that matter (scan, deep engagement, reply). Point it at a live target list and the "could you run this on my market?" answer is an honest yes.
