Update (as of Dec 1 2021): We’ve closed down the Day Zero community. 

If you’re an aspiring or zero-stage founder,  check out the Idea Activator, a new program designed specifically to help you learn how to navigate the idea maze, and do so while embedding into a tight-knit community of entrepreneurs.

Day Zero by Day One - Community for exploring and validating new business ideas | Product Hunt

What is Day Zero?


The insights that lead to actionable and innovative new businesses aren’t floating around Twitter. They live in the minds of leading experts, founders, and investors. So we host these folks for closed door conversations and have them share what they know. Then we write up the insights and ideas and send them to your inbox. You get inspired, keep up with trends, and save yourself months of research.


Great ideas aren’t born. They’re made. We provide you with proven tools, resources and methodologies to discover new ideas, craft and evaluate business concepts, and validate new business ideas. You’ll learn what good looks like and discard bad ideas without over-investing. You’ll create the artifacts and prototypes that allow for iteration, and feedback – until your ideas become great.


Network with hundreds of like-minded entrepreneurs, investors and experienced innovators who are all eager to collaborate. Find your next co-founder or investor, and get feedback, advice and fresh ideas from the community as you bring your ideas to life.
