Yup is backed by some of the biggest names in education

Yup is backed by Stanford University, where our mission to make expert tutoring more accessible for every student originated. Yup is also a member of StartX, an educational non-profit out of Stanford. StartX supports innovative solutions to the world’s toughest problems, which inspired them to admit Yup to the StartX class and become a backer. StartX only accepts 8% of applicant companies into the program, which guarantees access to resources like industry leaders and Stanford professors.

Yup is backed by Collab + Sesame, the official investment arm of Sesame Street. Sesame Street is a landmark global educational program that has helped people learn for 50 years. Collab + Sesame is dedicated to childhood educational development and provides portfolio companies with access to leading experts and resources. The fund chose to invest in Yup because of the differentiators that set us apart from other tutoring providers, including our proven and research-supported pedagogy.
