The Business Framework Compendium

Every framework a business and finance practitioner actually uses — 467 of them, one page each, in a single reference.

When you're mid-deal, mid-board-paper or mid-decision, you don't need a course — you need to find the right model fast, confirm how it works, and know its traps before you rely on it. The Business Framework Compendium is that reference: 467 models across twenty-five categories, from financial modelling and valuation to strategy, growth, risk, negotiation and ESG — each on a single, consistently structured page.

How every entry is built

Read one and you can read any. Each model follows the same rhythm:

• The question it answers — the decision or problem the model serves
• How it works — the method in a few steps, with its key components
• Inputs to outputs — what you feed it, and what you get back
• Who uses it & where — the roles and situations it belongs to
• Strengths · limits · pitfall — what it does well, where it breaks, the common mistake
• Practitioner notes — how it's actually used well in practice
• AI angle — where automation and AI genuinely help

The twenty-five categories

Financial Models · Strategy · Business Models · M&A · Private Equity & LBO · Corporate Finance · Valuation · Operating Models · Revenue · Cost & Profitability · Growth · Marketing & Customer · Digital & Platform · Innovation · Competitive Advantage · Risk · Investment & Portfolio · Startup & Venture · Turnaround · ESG · Management & Execution · Industry-Specific · Negotiation & Deal · Legal & Contractual · Teaching & Communication.

Who it's for

Analysts, bankers, consultants, founders, investors and operators who want one trusted place to find the right framework and use it well — without hunting across a shelf of textbooks.

How to use it

Read a chapter straight through to survey a whole discipline, or jump to a single entry when you're choosing a tool for live work. It's the map of what exists and when to reach for it.

The single-volume companion to the Business Model Handbooks collection — where the How to Master guides teach you to master each category, the Compendium is the reference you keep open beside them.
