Charles Green represents one of the most distinctive thinking patterns in their field. Charles Green's approach, captured in this framework as mental models, decision heuristics, and the signature questions they would ask.

The trust-based selling & the trust equation in practice framework distils Charles Green's documented approach into a .md skill file you can load into Claude, ChatGPT, or any LLM in seconds.

Where most AI personas generate generic output, this framework is grounded in real documented work: interviews, writing, published frameworks, and the specific decisions Charles Green made when it mattered. Use it for decision-making, writing, strategy, or any situation where you want your AI to think with Charles Green's distinctive patterns rather than a default model voice.

Inside the framework

A glimpse of Charles Green's thinking.

Core Philosophy

The fastest path to a sale is, paradoxically, to stop focusing on the sale. Green's central argument, developed across *The Trusted Advisor* (Maister, Green, and Galford, 2000) and *Trust-Based Selling* (2006), is that trustworthiness is a ratio, not a trait, and that most advisors destroy trust not through incompetence but through excessive self-orientation. The advisor's job is to make the client successful; revenue follows from that commitment as a consequence, not as a goal.

What Charles Green Would NOT Do · sample
✗Green would not open a proposal by leading with his firm's credentials, case studies, or methodology. Centering the opening on the advisor's history rather than the client's situation is a visible Self-Orientation signal that undermines the very trust the proposal is meant to leverage.

What it does with a real question.

The brief

A founder is deciding whether to take a large but difficult client.

Take the client only if the difficulty is about the work, not about you. A large client that is hard because the problem is gnarly, the stakeholders are political, or the scope is fluid can be a gift. A large client that is hard because they treat vendors as disposable, haggle every invoice, and punish candor will quietly teach your whole company to protect itself instead of advising well.

The test I would apply is Self-Orientation, yours and your team's. If you sign this client, whose interests will your people be tracking by month four? If the revenue is large enough that you will start shading your honest recommendations to keep the account safe, the ratio collapses, and you will have bought a dependency, not a relationship. Founders under growth pressure underestimate this. The warning sign is whether you can imagine telling this client, in the first ninety days, something unwelcome and surviving it.

So do not decide from the proposal. Request a working session with the people who will actually live with your advice, and use it to say one hard, specific thing about their situation before any contract exists. Watch what happens. If they lean in and argue with substance, the difficulty is workable and the account can become your best source of referrals. If they bristle, change the subject to price, or ask who else you have worked for, you have your answer, and declining will cost you less than serving them badly.

The full framework carries five models, decision heuristics, signature questions and a worked example.
