Piazza is and will stay free to instructors and students. We started the company on the belief that nothing should come in the way of learning. We continue to believe that. We also believe in best-in-class privacy and data protection, and would never do anything to betray your trust.
Our free Q&A service is funded through Piazza Network, a completely opt-in service that connects students with other students and employers to help find the most rewarding career opportunities. Our revenue source comes from there and we promise to work as hard as we can to keep it that way.
