Tenka Labs a maker of smart toys, raised $2.1M in seed funding. The investors were not disclosed.

Tenka Labs is an exciting new company that develops innovative STEM toys for Makers ages 8 and up. Its first product, Circuit Cubes, are electronic building blocks that bring kids' creations to life. They were built from the ground up to fully integrate with LEGO-style building blocks, but can be used with any materials kids can imagine - from vintage toys to recycled milk cartons. Circuit Cubes teach the basic fundamentals of electronics. Their unique transparent design enables kids to literally see the connections they make when they light an LED, power a motor, or activate a switch. Circuit Cubes can also be used vertically, horizontally, and diagonally to accommodate any design. Circuit Cubes were designed by STEM educators and FIRST LEGO League coaches, Nate and John.
