​YC S26 Welcome Yacht Party

​4th of July • San Francisco Bay

Join the newest Y Combinator batch for an unforgettable evening aboard a luxury yacht on the San Francisco Bay.

Celebrate Independence Day with fellow founders, mentors, and the YC community as we cruise past the iconic Golden Gate Bridge — watching a rare and historic fireworks display launched directly from the bridge towers for the first time in 14 years (only the third time in the bridge’s history).

Expect sparkling views, great conversations, champagne, and the electric energy of a brand-new batch kicking off an incredible journey.

The Prompting Company helps products get mentioned & used by AI agents. As agents become the first-class citizens of the internet, software needs to be rebuilt for agents, not humans. Companies like NVIDIA, Google, Databricks, Cloudflare, and Zapier are already using us.

Userlens builds AI agents that talk to your users. Based on their usage behavior, our agents find the best time to proactively message, email, and call your users so they adopt your product better and get more value.

​Sponsors:
