SpeedstrapA book from Third Sphere About the book

The AI companion

Use Speedstrap with your AI assistant.

Start with the exercise below. It's a simple interaction you can do with any AI assistant (ideally a frontier model). It includes the public principles we share, so you can start without uploading the book.

Start the exercise

01 / The starting point

Minimal equity.
Rapid revenue.

Speedstrapping makes this the primary plan. It can still take substantial capital; the question is where that capital comes from and when.

This exercise draws on the five edges described on the public book page.

  1. Revenue FirstGet to the first dollar fast.
  2. Customer-Funded GrowthExplore prepayments, paid pilots, and co-development.
  3. AI-Enabled EfficiencyConsider what agents can do before adding headcount.
  4. The Complete Capital StackUnderstand the options beyond equity rounds.
  5. The Living ModelKeep a current, honest model of what may happen.

02 / Put it to work

One constraint. One next step.

Copy the prompt, paste it into your assistant, and answer its questions. Approximate numbers are enough to begin.

You can also select and copy the text directly. The prompt includes its own framework; browsing is optional.

The assistant’s response is a starting hypothesis. Check its sources, assumptions, and numbers before acting. If you bring in a passage from your copy of the book, ask it to distinguish that passage from its own interpretation.

03 / Follow the evidence

Use the sources.

The source index

Follow the book’s citations to their sources. Bring the relevant evidence back into your conversation.
