The retail analytics firm, reach | influence, has relocated company headquarters from Royal Oak to the Madison Building in downtown Detroit.

“As Detroit-area natives we always wanted to play a role in the reviving central city,” says Rich Helppie, reach | influence board chairman. “The beauty of this move is that Detroit is the best place for a fast-growth company like (us) to bring together a client centric organization, local capital investment, and an operating culture that will foster the company’s future success.”

The company, with about 20 employees, provides services and insight to independent retailers and wholesalers to help them measure marketing efficacy and engage shoppers. It will share a 50,000 square foot space in the Madison Building with Detroit Venture Partners, Ginkgotree that helps students save money on textbooks, and iRule manufacturers of universal remote controls that connect with smartphones, among others.

Within the Madison Block, on Woodward Avenue and across from Grand Circus Park, there are six buildings with 100 companies and nearly 500 tech works.
