Corridor Business Journal: Des Moines-based Raygun has reported raising $582,000 in funding, according to a filing with the Securities and Exchange Commission. The chain, famous for its tongue-in-cheek, Midwest-themed slogans on T-shirts, postcards and other items, brings in about $4.3 million in annual revenue, according to corporate insight website Crunchbase. Raygun founder and owner Mike Draper said he raised the funds by selling company member units to "non-managing members" ? mostly other business owners he's known for years, and most of whom are Iowans.
