Close more deals with science on your side.
The prospect agrees with every word you said and still will not sign.
That gap is not an information problem. It is a decision problem — and the seven principles describe, with evidence, what actually moves a decision. You will learn which principle a stalled deal is asking for, and how to apply it without becoming someone your buyer distrusts.
The Science of Selling
Where deals actually stall
Deals rarely die in the pitch. They stall at four predictable points, and each one calls for a different principle.
01
Credibility in the first five minutes
A buyer decides whether to take you seriously long before you reach the pitch. Authority and Liking describe what they are reading in those minutes, and what you can honestly put there.
02
Objections, before they harden
An objection raised late is a position someone has already defended out loud. Reciprocity and Commitment let you surface the concern while it is still a question, when it costs nothing to change.
03
Decisions that do not get deferred
Most lost deals are not lost to a competitor. They are lost to no decision. Scarcity and Social Proof give a buyer an honest reason to choose now rather than later.
04
The second sale, and the referral
Unity explains why some accounts renew without a conversation and others churn despite a good result. It is the difference between a vendor and someone they consider one of them.
In the Room
Learned with peers, not from a lecture.
The POP Workshop is two days of hands-on work at round tables. Participants work through each principle together and practise it on situations from their own work.
