Watch list · business brain fuel

Ten films that teach
how businesses get built.

Branding, negotiation, data, pricing, distribution. Every pick maps to one skill I use on client work. Links go to JustWatch — it shows every legal place to stream, rent or buy in your country.

The Founder

Franchising & brand systems

Systems beat product. The burgers were the same everywhere — that repeatability is what scaled.

The Social Network

Network effects & growth

Launch narrow, own one campus, then expand. Exclusivity was the growth engine, not the ads.

Moneyball

Data over opinion

Buy the metric the market undervalues. Same logic behind low-competition keywords with real intent.

The Big Short

Risk & contrarian analysis

Read the raw data yourself. Consensus is often just everyone copying the same summary.

Steve Jobs

Product vision & positioning

Say no to 90% of features. Focus is what makes a launch land instead of leak away.

Joy

Ownership & persistence

Own your IP and your distribution deal. Whoever controls the channel controls the margin.

Pirates of Silicon Valley

Competition & speed

Licensing beat hardware. Whoever gets distributed the widest usually wins the category.

The Wolf of Wall Street

Sales psychology & ethics

Watch the sales mechanics, reject the ethics. Persuasion without honesty is a short business.

Air

Negotiation & partnerships

Bet the whole budget on one asymmetric deal. Royalty share turned a shoe into a $5B line.

Ford v Ferrari

Engineering & teamwork

Test, measure, shave seconds, repeat. Iteration under deadline is the whole discipline.
