From Pitching to Partying: How YC W25 Closed Out Demo Day in Style

For weeks, it was all about fundraising, traction, and perfecting the pitch.

Then, Demo Day arrived. A high-energy sprint where founders put everything on the line - telling their story, selling their vision, and chasing the next step in their journey.

But last Friday? It was time to celebrate.‍

A Well-Earned Night Off‍

At the Sansome Penthouse in San Francisco, YC W25 founders finally hit pause.

For one night, it wasn’t about the next startup milestone - it was about celebrating how far they’d come.

Free drinks, a live DJ, and an incredible crowd of YC founders filled the space, turning it into the ultimate post-Demo Day afterparty.

While Demo Day may be over, the journey is just beginning. The friends made, lessons learned, and momentum gained from YC W25 will continue to fuel these founders as they scale their startups.
