Our SmartKidsPlanet initiative began in 2017 when 3 geeky and dedicated parents saw a gap in the children’s toys and games market. An opportunity was spotted while we struggled to find toys and games for our kids which enriched their minds and guided them toward science, art, math and construction. The trio then knew that their paths were set, establishing an online shop with a comprehensive range of intelligent toys for babies, children and young teenagers.

With offices based in California, our SmartKidsPlanet team enjoys a daily growth in our presence within the children’s educational toys market. We love our new place in life, and we love helping young minds with their growth and skill development, all while having as much fun as possible.
