Using the 'X for Y' framework can be useful, but it must be done correctly; the 'X' should be a well-known billion-dollar company, and the 'Y' should represent a significant market opportunity.

The 'Y' in 'X for Y' should represent a huge market; if it sounds small, investors may worry about the potential for growth and whether it can become a billion-dollar company.

When using 'X for Y', ensure that the target market clearly wants the model being applied, and that it addresses a segment that is currently underserved.

A strong YC application articulates the idea concisely, avoiding vague marketing jargon, and demonstrates a significant market opportunity.

You should describe the problem you're solving rather than relying on vague comparisons like 'X for Y'.

A great pitch is one that can be easily understood by anyone, even someone unfamiliar with your industry.

When pitching to customers, use industry jargon to build credibility, encourage them to discuss their problems, and quickly demonstrate how your solution can help them personally.

Draft a one-sentence pitch that clearly states what you're building and who it's for, using jargon-free language.

Start your pitch with what your company does rather than why it exists, as this provides immediate context to your audience.
