Co-Founder Testimonials
"We were both skeptical of co-founder dating, but when Startup School launched their matching platform we decided to give it a try. After we were matched, not only did we hit it off immediately, but Startup School also guided us through the process of figuring out whether we would be a good team long-term. After joining forces, we discovered an opportunity that was more compelling than what either of us had been exploring individually."

Co-Founder Testimonials
"We met the day after we matched, and the day after, and then the day after that. It was challenging to know where to find the right co-founder, and I'm so glad we both tried out the YC platform and found each other. Our partnership has elevated Sequin and our mission to help women's credit outcomes."

Co-Founder Testimonials
"We were both working on separate products in similar spaces but felt we were missing certain skills individually - after we matched we found we complemented each other really well. We started meeting every day jamming on ideas before taking part in the YC Build Sprint. We’ve now been partnered for 7 months and we’re taking Dimensions into an accelerator before raising our seed later this year. Without Cofounder Matching Dimensions wouldn’t exist!"

Frequently Asked Questions
Who is eligible for co-founder matching?
Anyone who is seriously looking for a co-founder! You can have an established company, or no idea at all. You can be solo or already have a co-founder, as long as you’re looking for another one.
Can I use the platform to sell services or hire people for my company?
No. The platform is solely for seeking co-founders. If we receive reports that you’re using co-founder matching for anything else, we will remove you from the platform.
I don't have a startup yet, should I still enroll?
Yes! You can sign up for Startup School and co-founder matching if you are thinking about starting a startup in the future. This doesn't inhibit you from finding a co-founder.
Will my profile be public? Can my employer find me?
No, your profile is not public to the internet. Your profile is visible only to other people who have been approved for co-founder matching.
