Thanks to Paul Graham's advice and Y Combinator, I learned to create products that people truly need, and one of them is ProblemHunt. It's hard to put my gratitude into words, but I'm sincerely thankful to you guys. I really hope we can meet in person soon. 🙏

Dalton Caldwell, Gary Tan, and the entire team at Y Combinator are absolute legends. I could not be more grateful for their help and mentorship. There's a reason why it's considered the premier startup incubator in the world.

YC were instrumental in helping bring this project to life. Without the funding and guidance from the amazing mentors, we would not be nearly as far along as we are today.
