About Us

Andrew and Teisha Vandekop - EM Locator Technology

Hi! We're Andrew and Teisha Vandekop, the founders of EM Locator Technology, a featured start-up at World Water-Tech North America in 2023. Our journey began more than 20 years ago when Franz Vandekop, (Andrew's father and an electrical engineer) and Andrew (a robotics engineer), created the initial system. It was Franz who patented, developed and manufactured the first solid state over the horizon positioning system used by NOAA, the military and oil companies before the availability of GPS. With this expertise, Franz and Andrew set out to create a system that could fit in the back of a trailer and detect subterranean formations. After years of field tests and using the EM Locator Technology system on a variety of terrains, they were awarded two U.S. patents. Teisha then led the creation of Well Water Finders, a service-based company dedicated to helping landowners determine the availability of groundwater under their properties. In 2024, we’ll be expanding the geography we serve and adding a new focus, putting water back into our earth (Water for Earth). We plan to do this by working with municipalities to help recharge depleted aquifers.

Andrew Vandekop, Inventor and President

Andrew began his career in robotics engineering and sold his first patent at age 29. He's been in new product development his entire career and has applied these skills to three additional patents including the system developed by EM Locator Technology. He has spent the last two years conducting groundwater surveys on properties totaling more than 115,000 acres. During the time he spent field testing the prototype, he served as a founding team member of a telecom start-up that went public on the NYSE in 2006, serving as vice president of sales and customer service, managing 300,000+ customers over the midwestern U.S and contributing to revenue of more than $500 million.
