Sixty cards, three very different jobs. Deck KK0791, "Business Models & Revenue Strategies" on Flip It is one of the tidier glossary decks in the entrepreneurship shelf, and the fastest way through it is to stop treating it as a single list. Cards 1–25 are model archetypes, cards 26–32 and 46–50 are financial metrics, and the rest are strategy vocabulary you will meet in any pitch deck or product review.

How to drill it

Run the archetypes as a reverse deck: read the example, name the model. "Kickstarter" → crowdfunding. "Amazon Associates" → affiliate. "Uber surge" → dynamic pricing. The deck is written entirely term-first, so as written it never asks you to produce a term — and producing it is exactly what an interview or a pitch demands. Seventeen of the twenty-three archetype cards ship with a brand or product example, so the conversion is almost free.

Tip 1 — fix the gross margin card. The deck defines gross margin as "revenue minus cost of goods sold (COGS), expressed as percentage". Revenue minus COGS is gross profit, a currency amount; gross margin is that figure divided by revenue. Rewrite the back as (Revenue − COGS) ÷ Revenue before your first review, or you will carry the confusion into every unit-economics conversation.

Tip 2 — build one contrast card for the middlemen. Four cards describe a business that sits between two parties and takes a cut: marketplace (6), agency (20), brokerage (24) and platform (35). Their definitions overlap enough that spaced repetition will keep shuffling them without teaching you the difference. Make a single card asking "marketplace vs platform vs brokerage vs agency" and answer it in one line each — marketplace owns the transaction, platform owns the exchange infrastructure, broker is licensed and paid per deal, agency represents one side only.

Also worth a second look: card 38 lists Bitcoin and LendingClub as peer-to-peer examples, and LendingClub abandoned P2P lending in 2020 — swap in a current example. And note that "revenue model" (card 2) and "revenue stream" (card 46) are near-neighbours, not synonyms: a model is the strategy, a stream is a single source.
