New Enterprise Associates has led a $2.7 million seed round in Blend, a San Francisco-based maker of a social networking app for college students. Trinity Ventures, Foundation Capital, Lerer Ventures, Maveron, BoxGroup, XG Ventures and SparkLabs Global Ventures also joined in the seed round. The app is available for students in more than 3,500 universities nationwide, except those from Ohio State University. Blend co-founder and CEO Akash Nigam attended the University of Michigan before dropping out and launching Blend. As such, the company doesn’t allow students from rival school Ohio State to sign up for the app.
