Our Mission
We believe every student deserves the tools to become a better teammate, and every professor deserves insight into how their teams are really working together.
Our Story
CoStudy started at Boston University when two engineering students—Brock Nelson and Henry Kaufman—experienced firsthand the frustration of group projects without proper feedback mechanisms.
They noticed a gap: professors assigned group work to teach collaboration, but had no way to actually assess or develop those skills. Students received grades, but rarely actionable feedback on how to improve as teammates.
Traditional peer evaluations were clunky, biased, and told professors little about what was actually happening in their teams. There had to be a better way.
So they built CoStudy—a research-backed platform that makes peer evaluations actually useful. Today, professors at over 50 universities use CoStudy to run better team assessments and help students develop real collaboration skills.
