Tenka Inc., formerly known as IgnitED Learning, was founded in 2015 by John Schuster and Nate MacDonald with a focus on ed-tech toys for understanding circuits. They manufacture Circuit Cubes, electronic building blocks that help kids aged 5 and up create projects to enhance their tech literacy and circuitry understanding. Circuit Cubes feature a unique transparent design that allows kids to visualize circuit connections, enabling them to light LEDs, drive motors, and animate LEGO-style creations. These building blocks can be combined in various ways for unlimited project designs and integrate seamlessly with LEGO-style bricks.
