Phil Soran, one of Minnesota's most successful technology entrepreneurs of the past 20 years, and Jim Leslie, another veteran technology CEO, thought they had retired.
But their interest in education and philanthropy has put the fifty-somethings back in business.
Soran and Leslie have raised a whopping $17 million — a huge amount for an initial round of equity seed capital from individuals for a Minnesota firm — to finance the growth of start-up Vidku.com, a University of Minnesota online video-communication technology that Vidku has acquired.
"I built this for my classroom and it just spread," said Charlie Miller, one of three co-founders and an associate professor in the university's College of Education and Human Development. "We didn't spend a dollar on marketing and sales. And we had a third of the college on it."
Miller, 35, who is also director of the college's learning-technology laboratory, will soon resign from the faculty to join Vidku as an executive.
Vidku is based on "Flipgrid," a software codeveloped by Miller. It has found fans in education, business and elsewhere as the fledgling company tested interest over the past year.
Soran and Leslie were invited to look into the technology in 2014 by Jean Quam, dean of the College of Education.
"Flipgrid is a platform that allows individuals, at their convenience, to engage in rich, video-based dialogues with others organized around topics and questions," said Soran, who is executive chairman of Vidku. "Charlie is a Silicon Valley-class technology talent and a college professor who can present."
