I’m moving $1B of my Square equity (~28% of my wealth) to #startsmall LLC to fund global COVID-19 relief. After we disarm this pandemic, the focus will shift to girl’s health and education, and UBI. It will operate transparently, all flows tracked here: https://t.co/hVkUczDQmz

The opening

It opens with a number. I’m moving $1B of my Square equity (~28% of my wealth) to #startsmall LLC to fund global COVID-19 relief.

The shape

Hook → Landing

• Hook — Stops the scroll and earns the next line.
• Landing — Leaves the reader with the thought worth repeating.

Why it worked

• Leads with a specific number, which is concrete enough to be worth a second of attention.
• Uses concrete numbers instead of vague claims, which makes it credible and quotable.
• Written from experience rather than as advice, which is harder to argue with.
• Short enough to read in full without expanding, which removes a step before the point lands.
• Short sentences keep the pace up, so the reader never has to re-read a line.

What it leans on

• Specificity — exact numbers, named tools, precise dates — details that make a claim feel observed rather than asserted

How you would remix it

Preserve the Hook → Landing structure and the leads with a number opening. Replace the subject matter entirely with the writer’s own product, story and numbers. Match the original’s pacing and line length, not its words. Never reuse the original’s specific facts, figures or phrasing.

None of the words, none of the facts, none of the numbers — those are @jack's. The opening move, the shape and the place the payoff lands are what carry over. Open it in the studio with your own subject.
