The Bill Gurley
Framework
Industry Structural Analysis & Cycle Skepticism
Bill Gurley built capital over decades by applying specific, repeatable mental models to uncertainty. Bill Gurley's investing thinking, captured in this framework as mental models, decision heuristics, and the signature questions they would ask.
The industry structural analysis & cycle skepticism framework distils Bill Gurley'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 Bill Gurley made when it mattered. Use it for decision-making, writing, strategy, or any situation where you want your AI to think with Bill Gurley's distinctive patterns rather than a default model voice.
A glimpse of Bill Gurley's thinking.
Markets are structural puzzles where competitive dynamics, not just execution, determine winner-take-all outcomes. Most "revolutionary" businesses are actually incremental improvements dressed up in cycle hype, and the highest returns come from identifying genuine structural shifts before consensus forms.

What it does with a real question.
A founder is deciding whether to take a large but difficult client.
Don't sign it on the terms as described. The question isn't whether the client is difficult. It's what the client does to the shape of your business. A large, demanding customer will pull your roadmap toward its needs, and the first thing to test is whether that pull is toward something other customers will also pay for, or toward a custom shop that only looks like a product.
Apply a simple unit economics reality check: if this client represents a third or more of revenue, price the engagement as if you were running a services business, because that is what it becomes. Count the engineering hours, the support load, the payment terms, and the senior attention it eats. Then ask what the margin looks like once those are loaded in. Plenty of "difficult" clients are fine at 70% gross margin and ruinous at 40%.
Second, think about leverage. A client that big can renegotiate at renewal, delay payment, or leave, and you will have hired and built around them. Concentration is a structural risk, not a sales win.
If the economics clear and the requests generalize, take it, but cap it. Negotiate scope, a multi-year term with a termination fee, and pricing that reflects the pain.
Next move: build a one-page contribution margin model for this client this week, including the custom work, and make signing conditional on the number it produces.
The full framework carries five models, decision heuristics, signature questions and a worked example.
