In the 1970s, the city of Denver built the Denver Technology Center (DTC), an office park off Interstate 25 in the southwestern part of the Denver metro-area. DTC gives several big tech companies, including HP, Oracle and SAP, an outpost in the West. Late last year, an 80,000 square foot facility within the DTC, dubbed the Innovation Pavillion, was formed to co-locate startups with established companies, academic institutions and government organizations, according to the Denver Post. The median annual salary for tech workers at startups in the Denver metro area is $65,300.
