Rule4 Co-CEO Wins Colorado Technology Association APEX Award


Boulder, Colorado (Feb. 9, 2021) – Dan Mackin, co-founder and Co-CEO of Rule4, the Boulder-based cybersecurity and emerging technology advisory services firm, was named CEO of the Year at the Colorado Technology Association's APEX Awards ceremony on Feb. 4.

Each year, the CTA recognizes a "creative, innovative and determined founder or CEO" leading a Colorado tech company and "driving the vibrancy of the tech economy beyond their business." Mackin was nominated by his team, who said that "his energy, determination, and stubborn lack of complacency have helped our successful startup keep its foot on the gas and weather an extremely difficult economic and societal year." He was also credited as being a major driver behind the company's culture of giving, with an emphasis on safety net organizations including Sister Carmen Community Center, where he serves on the board of directors executive committee. 

Mackin and his co-CEO, Trent Hein, started Rule4 in 2018 and have led the company to impressive growth, more than doubling the size of their team in two years and ending 2020 with 58% revenue growth. They've also garnered accolades along the way that include the CTA's Entrepreneur Excellence Award, the Boulder Chamber Startup of the Year award, Certified B Corporation status, and being named a Colorado Companies to Watch finalist.
