This week’s 1 Million Cups at the Kauffman Foundation featured pitches by a high-tech roof-replacement business and an online showcase for grassroots apparel companies.

First up was veteran roofer Josh Davis, founder of Viirt, which utilizes satellite imagery to facilitate accurate roof measurements for consumers, leading to work estimates that can save time and money. The company negotiates with install-only roofing contractors to get the best prices for customers in the $56 billion roofing industry.

Viirt’s service is free to consumers, with every step of the process out in the open, Davis said.

“The No. 1 problem in the roofing industry is there’s no transparency,” he said. “We need to change this process.”

Davis pledged an average cost savings of 30 percent, in large part because Viirt helps its customers purchase roofing materials directly from suppliers without the typical markup from contractors.

Random Shirt Club at 1 Million Cups

Next onstage was Dom Green, founder of the Random Shirt Club. Currently in beta phase, the company is scheduled to launch its online sales platform on Oct. 15 for “grass-roots fashion in a mobile world,” Green said. The website will be committed to reflecting the latest in T-shirts and other cool apparel “city by city and style by style,” he said.

The Random Shirt Club will initially offer 10 local fashion brands and 30 others from manufacturers around the country on a consignment basis. The marketing goal is to engage customers not only with trendy styles that they may have never seen before, but with social-media-friendly lifestyle videos and blogs to tell the stories of each brand and its inventor.

“These aren’t just brands,” Green said. “These are artists and creators.”
