What YC can do to help co-founders find other co-founders

You're attempting to hijack their brand here way too directly.

This could be lawsuit potential. I doubt they'd do it, but I would personally think about taking the site down fast or just calling it PitchPlace.

As Pedalpete said below, YC doesn't even support these types of actions... so it's weak to try anyways.

There's a disclaimer at the bottom of the page.

If it meets the guidelines, this is likely better submitted as a Show HN.

What do you plan to prove with this by pretending it is affiliated with YC when they are quite clear they don't believe in 'co-founder meet-ups'?

How have they been clear about not believing in co-founder meet -ups?
