What is Day Zero?
I started Day Zero as a place to bring together early stage founders that just started their companies & operators looking to start their next company or looking to join what is next.
The goals of Day Zero is:
Attract top emerging founder talent in the SF Bay Area
Support early builders with community, access, and early-stage funding opportunities
Host IRL gatherings to build authentic relationships among the next generation of founders
Help top operators find their next moves and connect them to the best founders
