We're on a mission to create positive change for children.

3Si is a software company that helps governments and other partners use data to improve the lives of children.

Changing the Game in Early Childhood Data

The current state of early childhood data is fragmented, making it difficult to obtain a comprehensive understanding of the needs of children and families.

That is why we developed the Child Universal Success Platform (CUSP), an innovative data platform that enables governments and partners to access the data they need to help young children thrive.

We are Trusted Partners

3Si's commitment to quality and excellence has earned us a
reputation as a reliable partner in the quest to improve the lives of young children.

States, cities, and early childhood organizations across the U.S. rely on 3Si’s products and services. We are the leading provider of Early Childhood Integrated Data Systems (ECIDS) in the U.S.

Let's work together to create a better future for the next generation!

Join us in our mission to make high-quality education and social services accessible to all children.
