Expii is a social enterprise which seeks to build a world that embraces thinking. We produce three products, two of which are free, and one of which generates revenue to support everything. Our original free product is the website www.expii.com, which provides math and science mini-lessons for high school students. About 300,000 people visit it each month. Our second free product is the world’s first (and only) COVID-19 app which demonstrates the accuracy required for contact tracing (www.novid.org). It has the potential to significantly reduce the spread of COVID-19 worldwide.

All of this is supported by our revenue-generating product, which is a series of online math courses for middle school students (daily.poshenloh.com), taught by Expii’s founder, who is a math professor at Carnegie Mellon University and the national coach of the USA International Math Olympiad team. The courses themselves have been reviewed as the best-produced video courses for middle school math students seeking challenge beyond their school curriculum.
