Apply as an expert

We work with post-docs at top universities, faculty, Olympiad medalists, and domain experts from institutions like MIT, Harvard, IITs, and UC Berkeley. Every problem is verified correct and novel before we ship. We don't release until domain experts agree.

If you have deep expertise in mathematics, physics, chemistry, biology, or computer science and want to contribute, we pay for problem design and verification. Send a brief note about your background (affiliation, degree, competition or publication history if relevant):
