Our Story

Chalk is here because of teachers. What started out as William Zhou’s (CEO) quest to help his own teachers save time on their administrative tasks turned into a mission for improving education as a whole. He spent years studying the industry to create a solution that served teachers. His dream became Chalk. This has grown into Chalk’s vision of bringing personalized education to every student.

What We Believe

We understand that teaching and learning are deeply human undertakings, and we support professionals in bringing personalized education to every student. Personalized education is the key to bringing quality education to all, and to giving everyone an equal opportunity to participate in the future.

What We Know

Public education has been one of the greatest methods for students to receive equal opportunities in their formative years. However, the current model of education has not allowed children to realize their full potential. The opportunity to fully participate in the future remains out of reach for many.

A high-quality education is one that captures the imagination, engages the learner, and builds on skills over rote memorization. This kind of education cannot be automated nor mass produced; it must be nurtured through a professional dedicated to the needs of each student.

These eight tenets are the foundation of our beliefs at Chalk


That the personalization of learning is the best way to give equal opportunity to all learners.


That learning is innately human and is best possible with human guidance.

That teaching is a profession, not just a job.
That teachers are seeking new strategies and tools to personalize education at large scale.
That technology can help teachers differentiate instruction.
That saving teachers' time allows them to spend more time with their students.
That teachers can help each other to personalize education through collaboration.

That data and analytics on student achievement help teachers to better meet their students' needs.
