The ideas index
15 business models drawn from the entries in the database, each with its typical startup cost, net margin, and Boring Index. Ranked by dullness, which is to say, by merit. Where an owner in the database has reported a figure, the idea card uses it; the rest are typical industry ranges, marked with a tilde.
Not sure which fits you? Use the picker. Most models above have a documented owner in the database. Start there before you start anything else.
