Founding Story
SpotOn was founded by Ken Solinsky after an unexpected conversation with an irrigation contractor who mentioned how often he’d accidentally cut underground invisible fence wires while servicing sprinkler systems. As they talked, a simple question emerged: "Why wasn’t there a universal dog fence that worked for ALL yards and property?"
That question became the foundation for SpotOn. Solinsky envisioned a GPS-based containment system that could adapt to any terrain, acreage, or neighborhood restrictions, whether that meant dense woods, rolling farmland, or HOA-regulated suburbs. He then reached out to longtime collaborator and engineer Sung Vivathana, who immediately recognized the technical challenge and the opportunity. In 2015, SpotOn Fence was officially born.
What followed wasn’t a quick product launch, but years of deliberate engineering. The team rejected off-the-shelf GPS solutions, instead building proprietary hardware and software from the ground up to overcome the accuracy and reliability issues of current GPS wearable solutions (commonly used in the fitness industry). After nearly three years of development, testing, and refinement, the first SpotOn GPS Fence collars were released in 2019.
From day one, SpotOn’s mission has been clear: to design the most accurate and reliable virtual fence solution that would ultimately replace the need for physical fencing. That commitment to precision, fairness, and dog-first design continues to guide every generation of SpotOn products today.
