Kidaptive was an adaptive-learning startup founded out of Stanford University in 2011 by P.J. Gunsagar, a three-time entrepreneur, and Dylan Arena, a learning scientist. The company raised $30+M from investors including Formation 8, Menlo Ventures, Stanford University, and Cambridge University. Kidaptive’s mission was to empower learners of all ages, and their parents and teachers, by creating a vibrant ecosystem of personalized learning experiences. The company assembled a world-class team of researchers and engineers to support a long-term vision of a universal psychometric profile that supports learners as they explore the many powerful learning contexts available today: formal and informal, online and offline, from preschool learning through continuing professional education. On March 16, 2021, Kidaptive was acquired by McGraw Hill to become part of its Center for Innovation.
