# Buying and Fixing
Most acquisitions destroy value. Most turnarounds fail. The companies that succeed at these repeatedly have built something systematic — not just deal skill or operational heroics, but a machine that compounds through acquisition.
This section covers both sides: the assessment discipline that separates good deals from bad, and the operational playbook for the first hundred days and beyond. These are domains where all the other sections converge — you need to read the numbers, set direction, run operations, make decisions, and lead people, often under time pressure and incomplete information.

## Where to start
**[[Notes/The First Hundred Days|The First Hundred Days]]** — The window when everything is possible and nothing is stable. What to focus on immediately post-close.
**[[Notes/Harvest to Growth|Harvest to Growth]]** — The integrated playbook for rebuilding a growth engine in a business that's been starved of investment.

## Acquisitions
How to assess and integrate businesses that compound.
**[[Notes/The First Hundred Days|The First Hundred Days]]** — Post-close priorities: what to learn, what to protect, what to change. The window for establishing trust and tempo.
**[[Notes/Synergies That Deliver|Synergies That Deliver]]** — Most synergy cases are fantasies. What actually drives value, and how to tell the difference.
**[[Notes/Organic vs Acquired Growth|Organic vs Acquired Growth]]** — Different growth sources have different economics. How to think about the mix.

## Turnarounds
How to rebuild a business that's underperforming.
**[[Notes/Harvest to Growth|Harvest to Growth]]** — The complete playbook: find the constraint, protect what works, rebuild the engine. The synthesis of everything else applied to a struggling business.
**[[Notes/Fresh Eyes|Fresh Eyes]]** — The advantage of walking in without baggage. What new people see that old hands miss, and how to preserve that perspective.
**[[Notes/The Identity Constraint|The Identity Constraint]]** — The binding constraint in most turnarounds isn't operational — it's that the team doesn't believe change is possible. How to shift identity.

## Due diligence
The metrics that matter when assessing a target. This draws heavily from [[Reading the Business|Reading the Business]].
**[[Notes/Unit Economics|Unit Economics]]** — Does adding customers create value or consume it? The foundation of whether a business model works.
**[[Notes/Recurring Revenue|Recurring Revenue]]** — How hard you have to run just to stand still. The baseline that determines everything.
**[[Notes/Gross vs Net Retention|Gross vs Net Retention]]** — The difference between a leaky bucket and a growing one. Churn versus expansion from existing customers.
**[[Notes/Limits to Growth|Limits to Growth]]** — Every recurring revenue business has a ceiling. Where is it?
**[[Notes/FCF Conversion|FCF Conversion]]** — Do profits become cash? Earnings are accounting. Cash is real.
**[[Notes/EBITDA in Software|EBITDA in Software]]** — What the headline numbers hide in software businesses. Why EBITDA needs adjustment.

## Connects to
**[[Reading the Business|Reading the Business]]** — Due diligence is applied business reading. The metrics form the backbone of acquisition assessment.
**[[Running the Machine|Running the Machine]]** — Integration and turnaround are operational challenges. Flow and constraints determine success.
**[[Leading People|Leading People]]** — Turnarounds are fundamentally about people. The identity constraint is often the binding constraint in a struggling business.
**[[Making Decisions|Making Decisions]]** — Deal decisions are high-stakes predictions. The learning loop matters most when the stakes are highest.
