Jack Dorsey

Part I — The story

The story

Jack Dorsey co-founded Twitter, which reshaped public conversation, news, and politics by letting anyone broadcast short messages to the world — a simple constraint that created an entirely new medium. He then co-founded Square (now Block), which transformed payments by letting small merchants accept credit cards through a simple device plugged into a phone, democratising a capability once reserved for larger businesses. For years he served as CEO of both public companies at once.

Dorsey's work is united by a pattern of radical simplification — reducing a complex capability to something elegantly simple and widely accessible. Twitter compressed publishing to 140 characters; Square compressed merchant payments to a plug-in dongle. A minimalist by temperament, drawn to focus and constraint, he is a study in the power of simplicity as a product strategy, and in identifying a complex, gatekept capability and making it trivially easy for everyone.

Part II — The playbook

The playbook

Principle 1

Radically simplify a complex capability

Twitter and Square both reduced something complex to something elegantly simple.

Do this: Find a gatekept, complex capability and make it trivially easy for everyone.

Principle 2

Use constraint as a feature

Twitter's character limit created an entirely new medium.

Do this: A tight constraint can define a product and unlock a new behaviour, not limit it.

Principle 3

Democratise the gatekept

Square gave small merchants a capability once reserved for big business.

Do this: Open up to the many what has been reserved for the few — that's a market.

In their words

Make every detail perfect and limit the number of details to perfect.

Let the work speak. You don't have to add all the commentary.

Simplicity is the ultimate goal.
