What you actually get
Nominally a card in a curated directory of marketing tools for SaaS founders, alongside a well-read library of marketing playbooks. In practice the Airtable behind the site is failing: the tools page renders placeholder cards rather than listings and the home page raises its own "failed to get records" error, so there is nothing to appear in even if a submission were accepted.

How to submit to First 100 Users

  1. Open the form
    /submit is a free six-field form: first name, email, tool name, tool URL, tool description and a category. No account and no captcha.
  2. Accept the mailing list
    A line above the fields states that submitting adds you to their free list. There is no checkbox to decline it, so it is a condition of submitting rather than an option.
  3. Pick a category from the dropdown
    Category is a searchable dropdown offering Outbound, Email, Other, Analytics, Marketing and more. It has to be opened and clicked; the underlying input is invisible.
  4. Press Submit and read the toast
    The button posts to their Airtable datasource. On the walk it answered with a red "Something went wrong. Please contact us" toast and the submission did not land.

Gotchas

The submission failed on the walk: pressing Submit fires a real request to their Airtable backend and returns a red "Something went wrong. Please contact us" toast, with no way to tell whether anything was stored.
The same backend is failing elsewhere on the site. The home page raises its own "Something went wrong! Failed to get records" toast, and the tools directory renders nine identical placeholder cards reading "Heading3" and "Single line short text" instead of real listings.
Submitting subscribes you to their mailing list whether you want it or not: the page says so above the fields and offers no checkbox to decline, only an unsubscribe afterwards.
