Since our beta launch in 2017 with 300 users, we have grown to 30,000 families through a network of Dost Champions and strategic partnerships with preschools. By 2021, we will scale our “phonecast” product to 1 million families, work with researchers to refine the model for deeper impact, and innovate on new, rich-media prototypes for low-income families who are increasingly gaining smartphone access. After 2021, we anticipate working closely with state governments to integrate the most cost-effective components of Dost into the public preschool system.
