Why I built it

Compounding over decades fascinates me. Eli is how I look for the few businesses that can do it.

You’ll get very rich if you thought of yourself as having a card with only 20 punches in a lifetime and every financial decision used up one punch.

Warren Buffett

The hard part is saying no to almost every company.

The six steps

1Screen

Works by inversion: it looks for a reason not to buy, in the filings, the news and my notes on how companies fail. It can only say no.

2Classify

Works out what kind of business it is, because a software platform and a consumer brand can’t be judged by the same numbers.

CodeModel37%of those researched are kinds of business these steps don’t judge

3Analyse

Answers three questions: how does it make its money, what stops a rival taking it, and how long can that last?

4Score

Grades the business against bars set before any company is seen, so a good story can’t move the grade.

5Value

Picks the valuation method that fits how the business grows, with a margin of safety sized to its quality. A separate agent, which never sees the price, checks the reasoning and can only say no.

6Decide

A final synthesis puts every finding in one memo. A fixed checklist confirms each step was passed, and the memo stays a draft until a person approves it.
