Pre-Raise Evidence File: Launch, Pilot, Number

You have a waitlist, warm replies, and a product that is still a promise. Before you raise, make proof of demand checkable. A pre-revenue founder can do this by turning a waitlist into a dated launch, a pilot into a named cohort, and an outcome into a number.

Investors will ask for evidence. You can answer with a folder, not a pitch. The folder should hold artifacts that a skeptical reader can check. It should be easy to open and easy to explain.

If the file is thin, the conversation becomes about potential. If the file is clear, the conversation becomes about what happens next.

A dated launch is the public artifact

A waitlist can remain in a spreadsheet, but a public launch has a timestamp. Put the page, announcement, or waitlist in a folder with the date it was published. If the page changes, keep a copy of the original view. The artifact should answer a simple question: when did you make the ask public?

Catalyst publicly launched a waitlist in March 2026, and its October 2026 seed round came about seven months later.

The company disclosed a $30 million seed financing on October 8, 2026, with Sequoia leading and several investors participating.

Frontrun flagged Catalyst on February 20, 2026, 230 days before the October 2026 seed round.

A third-party note is not the same as a launch, but it can add context. For your file, the launch artifact should be yours: a public page, a dated announcement, or a waitlist that anyone can find.

A named pilot is a scoped test

A pilot is more useful when it has a name, a consent note, and a scope. Write down who agreed to test, what they agreed to do, and what they did not agree to do. If the product handles money, make the boundary explicit. The pilot should be a small agreement.

Catalyst's current product requires user confirmation before any money-moving step.

That kind of boundary matters because it tells a reader what the pilot actually covered. You can show the cohort, the consent, and the limits without extra detail.

A named cohort also protects you from overclaiming. If you say the pilot was for power users, say what power users meant in your context. If you say the pilot ran for a period, say the start and stop. The file should make the scope obvious, not implied.

Consent does not need legal perfection; it needs to be clear enough that a reader can tell who agreed to what.

A checkable number is the evidence

A metric is only as strong as its date, denominator, and verification method. If you claim adoption, say how many people were invited and how many completed the step. If you claim usage, say the window and the source. A stranger should be able to follow the number to the record.

Catalyst's pilot for its most active users moved hundreds of millions of dollars in trades across multiple weeks.

That number is useful because it is tied to a pilot, a user group, and a time window. It does not need to be perfect. It needs to be checkable.

Choose the number that best represents the outcome you want investors to believe. A tool can use completion, a marketplace can use activity, and a workflow can use time saved or steps removed. The metric should match the promise.

Verification can be simple. A screenshot with a timestamp, a query you can rerun, or a log export can all work. The method should let a skeptic repeat the check without your help.

A small file is easier to explain

When you meet an investor, the file should open quickly. Each item should be testable quickly. The file is a set of artifacts that lets a reader verify the story without asking you to repeat it.

Keep the folder small enough that you can explain it in a short meeting. If an item needs a long backstory, it may not be the right item.

• Dated public launch artifact: a public page, announcement, or waitlist with a visible date and a saved copy of the original view.
• Named pilot cohort: a short list of pilot users, their consent, and the exact scope they agreed to test.
• Checkable metric: a number with a date, a denominator, and a verification method a stranger can follow.
