OMAHA, Neb., May 1, 2013 /PRNewswire/ -- MindMixer, an online engagement platform helping hundreds of civic, education and healthcare organizations communicate more effectively with their constituents, today announced the closing of a $4 million investment round. Nelnet, a leading provider of innovative education products and services, led the round with existing investors Dundee Venture Capital and Optimas Group also participating. "MindMixer is poised to positively transform how large organizations, such as school districts and civic groups, across the nation communicate and interact with their desired audiences," said MindMixer CEO Nick Bowden. "With this new influx of capital, our online platform will provide more people with a new suite of tools to help them be heard and collectively arrive at solutions to problems, big and small." This new round will fund key developer hires and help the company scale to meet marketplace demand. Since its 2010 inception, MindMixer has increased its size by 40 percent each quarter and projects to reach 1,000 customers in the educational, healthcare and civic sectors by the end of 2013. The staff expansion will also help MindMixer continue to serve its current clients, such as the City of San Francisco, the D.C. public school district, Ohio State University and Coursera, to empower desired audiences to weigh in and provide potential solutions to hot button topics like school closures, deteriorating city infrastructure, and the current engagement pitfalls of massive open online courses. "MindMixer is an innovative approach to collaboration and engagement, allowing organizations to cultivate ideas from a broader community," said Mike Dunlap, CEO of Nelnet. "Nelnet is always looking for ways to improve the way we help associates, students, and schools reach their goals, so we are particularly proud to invest in a steadily growing company that engages people to attain the best results possible. Good ideas are everywhere, and MindMixer takes advantage of this fact with an easy and intuitive user experience." MindMixer will also apply its new capital to enhancing its current set of services and tools. Over the next few months, the MindMixer platform will feature a new and improved user experience, amplified website as well as significant mobile enhancements. These new product enhancements will increase community engagement and make conversations and the exchange of ideas between organizations and their desired audiences more efficient.
