There are seemingly few areas of the business world that Mark Cuban hasn't invested in. Now, EdSurge reports that the famed Shark Tank investor is getting serious about higher ed, calling it "a business that doesn't know it's going out of business." He added that colleges are "too concerned with looking and sounding good instead of delivering a product,” saying that higher ed spends too much money on fancy dorms and cafeterias —​ not to mention athletics —​ and not enough on improving student outcomes. It's a sentiment many in higher ed can likely relate to.

So where is the owner of the Dallas Mavericks, Landmark Theatres, and Magnolia Pictures placing his money in higher ed? Here are four startups he's betting will change the face of higher ed.

1. Copley Retention Systems

Copley Retention Systems' Copley Square application is focused on improving student success. It does this by pulling data from learning management systems, student information services, customer relationship management, and other campus systems into a single location, making it easier to provide early alerts when students are falling behind and allowing faculty and administrators to intervene.

Among its platform's other functions are smart phone notifications; a private campus social network; online video rooms for tutoring, advising, study groups, and faculty meetings; the ability for faculty and other campus personnel to leave notes and actions on any student; and more.

2. Ranku

Some students don't want the full campus experience and would prefer to get their degree entirely online. Finding the best fully online degree can be a difficult, strenuous proposition, though. That's where Ranku comes in, as co-founders Kim Taylor and Cecilia Retelle have essentially created a comparison shopping site for online degrees. The site partners with public, private, and state universities nationwide, helping connect prospective students to the best fit and weeding out those that are "call centers with a college built around it."

Cuban jumped onboard as an investor just three months in, with Taylor telling Women 2.0: "Mark believes there is a bubble in online education similar to the real estate bubble. Ranku makes schools shoppable and assigns an ROI to them based on job outcomes."
