Tetr College of Business (stylized as Tetr) is a private business school founded in 2022 by entrepreneur Pratham Mittal. Headquartered in New York City, United States, the school operates a rotational academic model, conducting instructional terms for its undergraduate and postgraduate students across temporary locations in several countries, including the North America, Europe, Asia, Africa, and the Middle East. The institution does not maintain a traditional permanent campus or a full-time residential faculty.
Tetr College of Business was established in 2022 by Pratham Mittal, who had previously founded the Masters' Union School of Business and the software company Outgrow. The institution was launched without a permanent campus, implementing a structure where student cohorts move between countries for different academic terms.
In November 2025, Tetr's parent entity raised approximately USD 18 million in a Series A funding round co-led by Owl Ventures and Bertelsmann India Investments.
Tetr College provides a four-year undergraduate Bachelor's program in management, technology, and artificial intelligence. Its academic model involves students completing successive terms in different international locations. Instruction is provided by visiting faculty and industry practitioners.
The school's degree-granting authority comes from its academic partnership with UBI Business School, which provides UK-accredited degrees. The college has also listed collaborations for specific modules or projects with institutions including Cornell University and the Indian Institute of Technology system.
In 2024, the college established Tetr Launchpad, a venture fund associated with student-led startups. Later that year, it announced the "Under 20" fund, a $10 million initiative targeting early-stage startups founded by individuals under age 20. The college has also operated scholarship programs for Indian students and for social media creators enrolling in its programs.
