"Car insurance is set prices by demographic: age, occupation, gender..."Root is a way for good drivers to cut their current insurance rate in half."Manger asked the Rundown's audience to download the app. The mobile phone app will learn about the individual's driving habits over the course of three weeks using smartphones, GPS and location services. Then, after the three-week period, Root could offer the user a quote for their insurance."We set prices based off of how individuals drive," he said of his Columbus-based operation.Mike Reed pitched Chartbuilder to the audience.it is a Tuscarawas County-based software startup which is working on a patient management and EMR platform for chiropractors and physical therapy practices. The team consists of a software developer, a chiropractor, and a physical therapist, so they really are “insiders” building a platform for their industry. Reed said their goal is to create a cloud-based management system that can ease the workflow of a therapist's office."The problem is 90 percent of clients use decade-old software that create inefficient workflows," he said. "With Chartbuilder, you can access it anywhere you have a browser: phone, tablet or computer."We have (human resources) and financial integration. Overall it is more efficient."Reed said the project is 75-percent complete.Tim Lowe made the final pitch to the audience about his concept, Eco Energy.The Mansfield company is using bio reformation technology to extract clean, usable Hydrogen (H2) from the organic materials in Municipal Solid Waste, while capturing their carbon content. So instead of sending waste material to a landfill, they are producing both H2 and electricity. The remaining materials are recycled and the water used in this process can be reclaimed for reuse. The process has acquired more than 20 patents, Lowe reported.He said the company can be profitable by selling the hydrogen and recyclables as well as other things reformed from the Municipal Solid Waste.
