About CK-12 Foundation

CK-12 Foundation is a nonprofit education technology organization offering high-quality digital learning tools and an AI tutor available for free to K-12 students worldwide. Founded in 2007, the organization brings nearly two decades of experience building open educational resources, including their Flexi AI Tutor and the CK-12 Curriculum platform.

Challenge

CK-12 Foundation needed to drive more sign-ups and platform engagement from teachers, parents, and students seeking free, high-quality K-12 learning resources. As a nonprofit competing for attention against well-funded edtech companies and large educational publishers, the challenge was reaching educators and families during the moments they are actively researching curriculum tools, STEM resources, and AI tutoring options. SmartSites built an education-focused campaign approach designed to grow awareness of CK-12's free offerings and convert interested visitors into platform users.
