I worked directly with the founder and she was fantastic. She was a great PM and we accomplished a lot over the course of the internship. Because the entire UI/UX team and development team were interns, I was able to make a huge impact on the products.
Cons
Jasper is a brand-new startup with maybe a handful of employees. My entire team were interns, and we were all unpaid. Other than that, working at Jasper was great and I gained fantastic experience because I was a full team member.
