About Us

Our Story

We’re helping students achieve success by breaking down the barriers to learning across the K-12 ecosystem.  We’re rethinking how technology can work together to inform and empower educators and students to improve the learning process.  Through technology and services, we facilitate collaboration, access to information, and effective use of tools to improve student performance.
