Launch EN is for companies from the Exponential Fellowship and Launchpad. Each company launches once.

Start the title with Launch EN:, then the company and what it does, in plain words. Launch EN: Acme (YC-style payroll for Spain) is better than a slogan.

Link to the product if people can try it. If they can't yet, leave the url blank and say what it is in the text.

Write to readers as peers. Say what you built, who it's for, what's hard about it, and what you'd like to hear. Answer the questions that come in; that's the launch.

No upvote rings and no marketing voice. Readers can tell.
