Share how you use AI in B2B negotiations

The Harvard AI Negotiation forum

Your negotiation starts before the first proposal

We have finished the twelve weeks of building the NegoAI platform in the open

The NegoAI app now helps buyers and sellers prepare for negotiation.

Last week I showed you the buying side. This week we added the selling side

We built an app to prepare your negotiation and practice it

At the start of this twelve-week build, I said I would share the work as it happened. This week, I can show you the app itself.

We built two more AI agents to help you buy and negotiate contracts.

A new supplier quotes a lower price per unit, so you consider giving them part of your order. But your current supplier will charge more per unit for the smaller order you leave with them. Once you add the two bills together, you are no longer saving money.

I'm building an AI agent to help negotiate the contract.

The contract arrives, and you have to negotiate that too. But you do not have the legal expertise to judge everything in front of you.

Moving the first agent took a week. The second took an afternoon.

Deepak first, then Kraljic, then the other three. By the end of the week the whole thing was running on my own server in Germany, the one I told you about in July, buying side and selling side. Brama, my partner in Claude Code, did the moving. I decided what to keep. I read every result.

Four negotiators. Every one of them could think like the other side. Not one had.

There are four negotiators who are not real people. We built them so I would have somebody to interview before I sit down with a client whose business I do not understand yet.

I have not been building the platform. I have been hiring.

Six weeks ago I told you I was building the NegoAI platform in the open. What I have actually been doing for six weeks is hiring.

I stopped writing notes before a meeting. I built the thing that gets me ready.

A company got in touch this week. They want AI and negotiation training, three sessions are booked, and before any of it I get forty-five minutes with the person who called.

I built four negotiators. None of them is a real person

I built them because before I sit down with a new client I want to understand how their work actually runs, and there is no way to learn that from a website, so I made people I could interview.

I Gave My AI Agent an Email Address, My Calendar, and Hands

This week I gave an AI agent its own email address, read access to my inbox and my calendar, and the ability to operate other software without me. Then I spent a day proving what it cannot do.

Week Two: Alex Learned to Say I Don't Know

Week two had one job. Give him a memory.

Week One: A Private Home for the Agents

Last week I told you I'd build the NegoAI platform in the open, over at least twelve weeks. This is the first build report.

I'm Building the NegoAI Platform in the Open

I'm building the NegoAI platform. And I'm going to build it here, in the open, over the next twelve weeks at least.

The AI Read the Room Better Than the Negotiators Did

The European Negotiation Conference had put four of us on one panel — AI and Human Interaction in Negotiation — and I had the last slot, presenting the work behind the paper I shared with you last week.

Human + AI Usually Loses. Here's When It Wins.

For a year now, I've prepared every negotiation with the same AI. The common assumption is that this kind of partnership gets better on its own — more time together, sharper work. For most people, it doesn't. They plateau, or quietly give up.

The Hard Part Was Never the Code

This week my course cohort finished a working AI negotiation system — without writing a single line of code. The part that decided whether it was any good had nothing to do with the building.

You Don't Have to Trust the Other Side to Make the Deal Bigger

How AI creates value in low-trust negotiations — and the agent my cohort built this week to do it.

Last Week the Tool Fought Me. This Week, Four Questions Built the Agent.New post

I Built a Negotiation Workflow with Microsoft Copilot Studio — The Honest Version

Here's exactly what I built, what it took, and whether it's worth your time.

Your AI Has Read About Negotiation. It Hasn't Learned It

What AI training only gives you is the average of the internet. A knowledge base gives you something better — real expertise, including your own.

When One Assistant Runs Out of Road — I Built the Chain Live

On Monday — in the second of two Maven Lightning Lessons — I took the same negotiation case from Part 1, ran it through a four-agent workflow, and handed the final brief to Von Neumann for a live counterpart stress-test.

I Built It Live on Monday — In Two Tools

On Monday — in the first of two Maven Lightning Lessons — I built a working AI negotiation prep agent live, from zero.

Why We Built Von Neumann

The gap between preparing for a negotiation and walking into one is the gap between knowing your strategy and stress-testing it against a sparring partner who can push back. We built Von Neumann to close it.
