CITE THIS CARDTHE RUNWAY CARD, Edition 2. Lund Studio LLC, Westminster, Colorado. https://lundr.tech/?view=runway-card. Punch 52F5C054032B3E02EBA539DD. Retrieved 2026-10-10.

What it is.

Cash on hand, monthly burn, monthly revenue and its growth go in; months of runway come out under three scenarios — as planned, revenue flat, revenue half — with the month the cash is gone.

Three scenarios, always; one number is a hope.

Its laws, written into the card.

  • Three scenarios, always; one number is a hope.
  • Growth compounds monthly, as stated.
  • It computes; it never advises.

How it works, once your AI has it.

  1. NAME — `This is THE RUNWAY CARD.`
  2. ASK — cash, burn, revenue and growth.
  3. COMPUTE — the months, three ways.
  4. RERUN — with the numbers the plan actually changes.
  5. WRITE — the three into the ledger.
  6. LEDGER — write the ledger line.

When it says no.

  • Forecasting revenue; the growth number is the holder's — FUNANCE keeps the books the numbers come from.
  • Saying what to cut.
  • Printing one scenario as the answer.

What’s in the buy.

  • CARD.md — the whole card · SKILL.md — the door your AI reads first · START-HERE.md — the first five minutes
  • references/THE-METHOD.md · EVALS.json · EVALS.md · scripts/evals.py — the method, its template, and the tests with their runner

ON EVERY DOOR · A CARD FOR YOUR AI, A FILE FOR YOUR COMPUTER

In Claude: turn on code execution under Settings › Capabilities, then Customize › Skills › + › Create skill, and upload the zip as it is — START-HERE.md in the box walks you through it, and tells you how to keep the ledger. In ChatGPT, Gemini and the rest: a Project, a GPT or a Gem with the card’s files attached and the short door in the box pasted as its instructions. The words run anywhere an AI reads Markdown; the machines run wherever the host runs Python. Witnessed in Claude only. The host marks →

Take it.

Nº 682 PROPOSED · ONE PAYMENT

Sold as is under the term printed. A card instructs an AI you operate; results depend on your model, your files and your judgement. Not legal, tax, medical or financial advice. The terms →

ONE PAYMENT · NOTHING RENEWS ITSELF

OFFLINE · ONE LICENCE · PUNCH-CHECKABLE · THE STANDARD

One payment. The file is yours to keep and keeps working at its edition; new editions issued in the year after you buy reach you by email as replacement files. Tax is added at checkout where it applies. Nothing auto-renews.

One email when it is on sale, from the studio; nothing else, ever.

ONE PAYMENT — NOTHING RENEWS ITSELF. CHECKOUT IS SHOPIFY’S OWN; YOUR CARD COMES BY EMAIL AFTER IT.
