JOHN PRINNER - President & CEO
John has been a lifetime entrepreneur and innovator with several successful private-equity backed companies. Over the last ten years he has founded and run companies in early growth stages that have challenged the ‘traditional ways’ of doing business and competed successfully against much larger publicly financed companies. Always focused on making technology work for consumers, John led one of the first companies to offer cable television, telephone and internet service over one proprietary Hybrid Fiber Coax network, commonly referred to by the large cable and telecom operators as the “triple-play”. Not only have these businesses delivered superior products and services to their consumers, but they have also delivered exceptional returns to their shareholders. His experience bringing to market consumer friendly products in high technology environments has been a key ingredient to establishing Vivaro (through its subsidiaries) as a key destination point for Hispanics looking to find highly relevant and reliable communication and financial services solutions.

His background includes counseling and advising numerous venture funds and emerging growth companies at Gunderson Dettmer and has held several other positions working with venture and private-equity backed companies, including Pfizer-Shiley. Dan holds a BA in Economics from Georgetown University, a JD from Northwestern University School of Law and took advanced coursework at Kellogg School of Management.
