Jessica Livingston's book "Founders at work" (2007, 32 stories) inspired thousands of founders to start their startups.


I find and put in one place 150+ founders stories to inspire new wave of founders. (+pitchdecs, 1-minute videos, demo day videos, applications, and “early workplaces”). And I am finding every day more and more stories! Sometimes I think that stories find me. Today it is impossible to write and publish material book about YC founders, let it be a digital, neverending book, that writes itself.


It was an amazing journey, it changed my mindset. I rushed into unknown unknowns, where angels fear to tread... and I want to share this with everyone.


I hope, that FoundersAtWork.io saves 50-100 hours for 1000+ new founders. It is my "embarrassing MVP" I continue to work on, and I need your feedback.


Everyone can contribute founder's story!
