As Denver grows by leaps and bounds, tech companies continue to put down roots in the metro area.

Among the latest notable tech real estate purchases:

Microsoft: The company recently paid $63.5 million for around 260 acres of land south of Denver International Airport, according to the Denver Business Journal. The land is directly south of Denali Logistics Park, a joint industrial and logistics development between L.C. Fulenwider and Hines.

Blue Origin: Jeff Bezos’ rocket and space company has taken office space in Highlands Ranch. The Washington-based company began recruiting workers in Colorado earlier this year, according to the Denver Business Journal, which reports that “According to its website, Blue Origin’s south Denver office will be a hub for ‘program management, systems engineering, avionics, software, integrations and mission design in support of our launch vehicle and space systems programs.’”

Amazon: The company has purchased 152 acres near Northern Colorado Regional Airport in Loveland, causing speculation that it has plans to build a “mega” distribution center in Larimer County, according to the Coloradoan. Amazon paid $9.4 million for the land. It already leases 123,000 square feet in a development adjacent to the airport, notes the Coloradoan.
