It’s a company born out of the recession that, thanks to some good networking and a little luck, has turned into a design firm that represents some of the biggest names in tech. San Francisco-based architecture and design firm Blitz, whose clients include Google (Nasdaq: GOOG), Microsoft (Nasdaq: MSFT) and Instacart, opened an office last month at the Ctrl Collective co-working space inside the Dairy Block. After considering Portland, Oregon for its third office (it’s second office is in Los Angeles), co-founder Melissa Hanley, who started the company with her now-husband Seth, said watching the number of companies defect from the Bay Area to the Rocky Mountains made the decision to locate in Denver a no brainer.
