Where It Started
The Original Drawing
Before there was a product, there was a sketch. Michael Pfeiffer drew the TetherKing concept by hand — the same idea you see in the field today. Built from scratch. Designed by a founder who never stopped believing in it.
Original concept art — hand drawn by Michael Pfeiffer, Founder of MantisPro LLC
That's not a prototype. That's a vision. Proven in backyards, parks, and baseball fields across Arizona.
