Project Skyway's second class will make presentations to investors

Four tech firms from Minneapolis accelerator Project Skyway will present their business plans to local investors on Wednesday.

The companies are: YumZing, a business that lets users review dishes at restaurants; HypeSpark, a firm that encourages users to endorse brands on social networks; Energy Resource Insights, an information database for the energy industry; and Political Harmony, which lets voters choose candidates and campaigns to reach hard-to-poll voters.

The businesses are part of Project Skyway's second class. Project Skyway offers promising tech firms perks such as workspace, funding and access to mentors and developers in exchange for a 9 percent equity stake.
