We are creating a world where everyone can advance through the doorway of literacy

Good things happen when teachers, education advocates, and technologists join together for a massively transformative purpose


to the books students want to read and teachers want to teach


through personalized libraries and
adaptive assessments


with real-time data that fosters a
growth mindset


students, classrooms, and school
districts exceeding literacy goals

One in nine adult Americans struggle with employment outcomes as well as personal and social well-being – all because of low literacy skills. LightSail is dedicated to turning students into readers who will become engaged global citizens in the 21st Century.

So, in 2012 we got a group of the brightest minds in education together to create the world’s best literacy solution. We knew a few key things from our experience in the classroom:

    • Students grow faster when engaged and challenged by an abundance of just right texts

    • Students are motivated by understanding their own progress data

    • Educators can do more with better progress monitoring

So we set to work crafting, testing, and perfecting the reading experience we wish we had in our own schools.

Today we are advancing literacy in schools all across the US, serving hundreds of thousands of students across nearly 500 districts.
