Startup School 2018 - from Y Combinator is a free online course for startups.
We met several other cool founders and had a great mentor. The advice is super valuable.
20+ teams to 1 mentor is a bit much.
We were in the first batch. The weekly syncs were great because we could ask a bunch of questions and get feedback. They also kept us accountable to driving out metrics week/week. We also keep in touch with our mentor, a year later. A few teams, including ours, got to participate in live office hours with Sam Altman. It was a great opportunity to practice speaking and get some exposure. We wrote about our experience here: https://canny.io/blog/what-youll-get-out-of-y-combinators-startup-school.Sarah Hum has used this product for one month.
The mentors (mostly YC alum) and small group sessions with other founders are so valuable.
You'll be surprised with what you can accomplish in 10 weeks. I wrote about my experience in last year's Startup School here: https://www.producthunt.com/posts/startup-school#comment-484477Kunal Bhatia has used this product for one year.
