A1Zap is a social network where people build AI-powered apps for each other. Made by A1Base, a San Francisco consumer-AI lab in Y Combinator's Winter 2025 batch, it lets anyone spin up chatbots, tools and mini-apps without code and share them instantly into group chats and communities, starting on college campuses. The team began as an API giving AI agents phone numbers, emails and a trusted identity, then pivoted toward building the social distribution layer for AI apps.

Dalton Caldwell is a serial entrepreneur turned venture capitalist best known for co-founding imeem (one of the first legal music social networks), launching App.net as a principled alternative to ad-supported social media, and spending over a decade as a Managing Partner at Y Combinator advising 1,000+ startups. He is now co-founding Standard Capital, a $425M AI-native Series A fund with Paul Buchheit and Bryan Berg.

Dustin Moskovitz co-founded Facebook in a Harvard dorm room in 2004, then quietly built Asana into a billion-dollar project management company while giving away billions through Open Philanthropy (now Coefficient Giving). The youngest self-made billionaire in the world when Forbes first named him in 2011, Moskovitz has spent the years since turning wealth into what he believes are the most high-impact charitable causes on Earth - from malaria nets to AI safety - alongside his wife Cari Tuna.
