Kids digital media brand Epic! has raised US$8 million to accelerate the growth of its subscription book and video service both in homes and schools.

Series C funding for the California-based content and learning platform was led by Reach Capital with participation from TransLink Capital, Rakuten Ventures, Menlo Ventures, WI Harper, Brighteye Ventures and Innovation Endeavors. Over three rounds, Epic! has raised a total of US$21.4 million.

Epic! provides under-12s with unlimited access to more than 25,000 curated books and videos. The platform—available on Android, iOS, Apple TV and all web browsers—reaches more than five million children globally, providing access to non-fiction titles, picture books, chapter books, graphic novels, “read to me” books, learning videos, quizzes and reading lists.

To date, Epic! has partnered with 250 publishers and video providers including HarperCollins, Macmillan, Sesame Workshop, National Geographic Kids and Smithsonian Enterprises. The subscription service’s content is selected by a team of children’s publishing experts, and Epic!’s recommendation algorithm tailors content offerings based on the child’s reading level and preferences.

In 2015, the startup launched Epic! for Educators to provide elementary school teachers and school librarians with free access to the platform, which is now used in 87% of elementary schools in the US.

Since its launch, more than 160 million books have been read through Epic!, with kids perusing 24 million titles in the past month alone, according to the platform.
