Who would you recommend as a mentor on ProductHunt?

We build a platform for teenagers to help them make something cool and find their ✦ passion by hosting classes with unique professionals. Now we are working on a course about startups and looking for mentors to inspire teenagers to make their own ✦ products. If you are ready to share your product development ✦ experience, warn against missteps, and explain how to test an idea, please write in the comments ↓. If you don't feel ready for this, recommend ✦ people you've learned from. Just mention them here, and we'll message them directly. We will be very grateful for your ✦ help. ♥︎
