In 2018, Tellmewow, a video game and mobile app development studio, was born in Bilbao.

It currently has a catalogue of more than 150 mobile games available for different operating systems that have accumulated 900 million downloads.

Today, the company publishes games under two brands and types of products: Cool Senior Games and Edujoy by Playkids. The first is specialized in the creation of mobile games with a focus on accessibility and usability, which makes them ideal for older people and for those looking for casual games without many complications.

The second develops educational applications and games for children. Its mission is to create fun and interactive learning experiences that inspire curiosity and a love of knowledge in boys and girls.

This brand was created as a company in 2011 by Alberto Iglesias, one of the founders, who made the decision after being unable to find quality educational video games for his children. And in 2018, together with Isabel Liébana and Urtzi Jaureguibeitia, he created Tellmewow. Video games are a fun way to learn about different areas of knowledge and topics.

Currently, it has a catalogue of more than 150 mobile games available on iOS and Android that have already accumulated 900 million downloads, and in 2021 the studio was acquired by the Sandbox Group, based in London and with companies located in the United States, Brazil and the United Kingdom.
