Hi PH! I’m Cat, and I’m one of the engineers that worked on the YC library, alongside @katherine_bernstein. We’re excited to show you the reimagined YC Library! We first launched the Library in 2020, and it has proven to be a tremendous resource since; much of the stuff in there has been viewed hundreds of thousands or millions of times. With this redesign, it’s much easier for founders to keep up with our growing lineup of new video series and and for future founders to explore the wealth of content we’ve made over the years. The new Library will always be growing — as we release new content, as we expand its archives of prior releases, and as we continue to build out its functionality. If you have any ideas for things we should add to the library, let us know in the comments!

Hey Cat, great to see you here! Congrats to you and @katherine_bernstein for the reimagined YC Library. It sounds like a fantastic resource for founders. I love how you mentioned that it's easier to keep up with the new video series and explore the wealth of content. I have a question for you - besides videos, essays, and podcasts, are there any plans to include other formats of content in the Library, like interactive workshops or case studies? It would be awesome to have a variety of resources to cater to different learning styles. Keep up the great work! 👏📚

Hey! I'm Kat, one of the engineers who worked on the YC Library with @catheryn. I'm so excited to be sharing the new Library with all of you! Let us know if you have any feedback, questions, or suggestions :)
Thanks for launching this! Much easier that scouring the internet for every single YC bit of advice! We at Clustr will definitely make use of this on our next application🤩
