In a recent episode of my DEALMACHER podcast, one of my guests put words to something I coach founders on constantly: there’s a difference between a demand and an argument – and confusing the two costs you money.

The guest was Matthias Schranner – FBI-trained hostage negotiator, advisor to governments and the United Nations, and a man Forbes has called one of the best negotiators in the world. His distinction is one most people never make. An argument invites a counter-argument. A demand doesn’t.

Here’s the sentence that gets founders in trouble: “Our valuation is X, and here’s why.” Everything after “here’s why” is the mistake.

When you explain why your price is justified, the other side explains why it isn’t, and now you’re trading rebuttals. “The moment you argue, you get a counter-argument – and then you’re fighting, not negotiating.” Fighting has winners and losers. Negotiation, done well, leaves neither side cornered.

A demand works differently. It doesn’t need a justification. It needs a storyline – a narrative that leads naturally to the number, the way a good story leads to its ending. Founders, of all people, live from storyline. You’ve pitched the vision a hundred times. The skill is to carry that same narrative arc into the number itself, so the price feels like the logical next line of the story, not a claim you now have to defend.

Then comes the part almost everyone fails.

After you state the number, you stop talking.

Schranner is blunt about it. Most people walk in, present their number, and then keep going. They explain. They soften. They fill the silence. “And then they keep talking – and they destroy everything they just built.”

The number was strong. The thirty seconds after it weren’t. Say the price. Hold eye contact. Wait. The silence is doing work; don’t rescue the other side from it.

This is hard because silence after your own demand feels like exposure. The instinct is to justify, to show your reasoning, to prove you’re being reasonable. But every extra sentence is a small retreat. You’re negotiating against yourself in real time, and the other side hasn’t even responded yet.

There’s a mindset shift underneath the tactic. Schranner frames negotiation as testing, not stating. You’re not announcing a fact and defending it. You’re placing a position on the table and watching what comes back. A demand is a probe. An argument is a stake in the ground you now have to die on. Probes give you room to move. Stakes give you a fight.

So the move is almost embarrassingly simple, and almost no one executes it cleanly: build the storyline, let it carry you to the number, say the number, and then shut up.

It’s one of the first things I work on with founders before a major negotiation – and one of the hardest to actually hold under pressure. Try it once, exactly like that, in your next real negotiation. Resist the explanation. Sit in the quiet. You’ll feel how much you normally give away in the seconds you were trained to fill.
