Our Story & Team


About a decade ago...

While having lunch, Co-founders Dennis Hackemeyer and Mark Sisson observed several “interesting behaviors”:

  • A waitress “cleaned” a table close by with a dirty wash rag.
  • A mother with a toddler wiped her table with disinfectant wipes and used hand sanitizer on her child's hands.
  • A patron coming into the restaurant sneezed into their hand right before opening the door. (The restroom floor was also littered with paper towels from people afraid to touch the door handle.)

What they observed prompted these epiphanies:

  • People are concerned about cleanliness – and for good reasons.
  • The act of cleaning isn't enough. You also must deliver a feeling of safety and security by making clean visible.
  • Delivering visibly clean surfaces when and where it's needed is most effective, rather than over disinfecting.
  • There had to be a safer, healthier, and environmentally friendly way to deliver cleanliness in public spaces.

Shortly thereafter, Dennis and Mark set out on a mission to combine nanotechnology, the natural power of light, and the latest material science to create cleaner surfaces. After 7 years of R&D, the Nanotouch Self-Cleaning Surface was born.

Our Leadership Team

  • Dennis Hackemeyer

    Ask the company co-founder about his vision for Nanotouch, and his answer is far from understated: Bring change to the world. The former Marine, whose background combines advanced print technologies and Marine Corps training in nuclear-biological-chemical, sees Nanotouch as having a global impact, helping redefine how we think of clean and enhancing the safety of public spaces in the most environmentally conscious and ESG- compliant ways possible. Dennis helped to oversee the launch of Nanotouch through the research, antimicrobial lab testing, product development, and fabrication processes and today leads the company’s business development and partnership initiatives.

    He is a graduate of the Virginia Military Institute where he received his BA in Economics. He also received training at the U.S. Army Airborne School, the U.S. Navy Scuba School, the U.S. Army Tank School, and the USMC Mountain Warfare School, where he learned to Adapt-Improvise-Overcome. Try going from a business suit, starched shirt, and tie – with three preschoolers at home – back to camouflage utilities four days after being re-activated for Operation Desert Storm. It’s that dedication to the mission that makes Dennis such a successful entrepreneur.

  • Mark Sisson

    Co-founder Mark Sisson is the company’s resident mad scientist – one part visionary, one part philosopher, one part tree hugger. Prior to co-founding Nanotouch in 2012 with partner Dennis Hackemeyer, Mark led an award-winning ad agency that specialized in industrial marketing that combined data and psychology to create highly effective campaigns. As a thought leader in self-cleaning technology, he is the author of editorial content for prominent industry publications such as ISSA Today, including articles such as The Psychology of Clean, NanoTechnology-The Next Really Big Small Thing, and most recently The War on Germs Goes High Tech. He is a past board member for Centra’s Specialty Hospital. Mark is a graduate of Virginia Tech with a degree in Computer Science.
