After his company got a boost from his appearance on ABC’s “Shark Tank,” Colorado entrepreneur Anthony Franco said the business has continued to grow despite the coronavirus pandemic. The company, mcSquares, has quadrupled the size of its physical operations, expanding into a 25,000-square foot building in Thornton. Franco, founder and CEO of the startup, said the 600% growth it reported in the first quarter of this year has continued. In addition, the company has landed a deal with the Novi School District in Michigan that will put its personal whiteboards in the hands of more than 6,000 students and teachers.
