A harness is what a clone pretends to be: a consented, verifiable record of how your best person thinks. It answers with what they actually said, and refuses what they didn't. Nobody has built a perfect one yet. Someone will.
A weekend project can wrap a system prompt in someone's name and call it a clone. It sounds right up until a customer asks something the real person never actually answered. Then it guesses, confidently, in their voice. That's a liability wearing a costume.
Vercel trained an agent on its top seller, and that one person's judgment now handles the work of its entire 10-person inbound sales team. The best performer, multiplied, already pays. And that is the costume version paying. The verified one is worth more.
Vercel, reported 2026Recordings, transcripts, notes, decisions, pulled from the tools you already run. No interviews, and no homework for the expert.
The harness says "I don't have material on that" instead of guessing in someone's voice.
The source person approves what's included and stays in the loop as it evolves.
Swap the model underneath and the judgment carries over. No vendor lock-in.
Five stages sit between a real person and a harness worth trusting. Skip one and you've built a costume.
Everything that shows how someone actually thinks: recordings, transcripts, notes, past decisions and the reasoning behind them. The corpus already exists in the tools a company runs: Gong and Outreach calls, Zoom recordings, Notion pages, Google Drive docs, CRM history. Nobody sits for interviews. The harness is built from what is already there.
Tone, vocabulary, what they emphasize, and the route they take to an answer, not just the answer itself. The reasoning pattern is the real asset. We extract it and make it reusable.
Some harnesses should sound like the person. Others only need to think like them. Sounding like them is a separate step, and always opt-in.
The stage most clones skip. A harness has to know what it doesn't know, and say so, instead of guessing in someone else's voice. Trust lives or dies right here.
The real person stays in the loop. They approve what goes in, revise it as their thinking changes, and share in the upside when the harness is used beyond their own audience.
The rep who always knows which objection to handle first. Captured the right way, their approach becomes something the whole team can learn from, not a black box that replaces them. Their judgment is already sitting in Gong and Zoom. The only question is whether anything gets built from it.
Thirty years of judgment walks out the door on someone's last day. A harness built with their consent before they go keeps that judgment in the building: askable, sourced, and honest about what it never covered. The retiree stays in the loop, and shares in the upside when it's used. Built before the last day, it's corrected by the person. Built after, it's guesswork.
The first person most leaders want to clone is themselves. A personal harness answers the questions you've already answered, drafts the way you actually draft, and hands anything genuinely new back to you. You are both the source and the reviewer, so consent is built in. The pipeline's discipline is what keeps it honestly you.
Harness 001 is our own founder, built from his own corpus, and the demo is a dare: ask it something he never said, and watch it refuse.
If your team's best thinking is stuck in one head, or your most experienced person has a retirement date on the calendar, get in early. We build a few at a time, on purpose.
