Mark Calkins
Co-Founder, President

Mark Calkins is a technology enthusiast, motor head, and a general knowledge-seeker. He is intrigued by stability at scale, and simplicity through complex abstraction.

Mark has over twenty years of experience in the Telecom/MSO/Service Provider segment with a proven track record of ingenuity and dedication to the craft. Mark is very excited about the non-profit IX movement because he feels it is an excellent way to give back to the community in which he lives by improving connectivity for all people in the region.
