Startups that operate in the American Underground, a trio of business incubators in Durham and Raleigh, created 244 new full-time jobs and an additional 79 part-time jobs over the past 12 months.
Moreover, employees of American Underground companies spent an estimated $674,700 at downtown Durham and Raleigh establishments over the past 12 months.
"Our companies aren't holed up within our four walls," said Adam Klein, American Underground's chief strategist. "They're active members of our communities."
American Underground, which got its start in 2010 when it opened its first site in Durham's American Tobacco Campus, unveiled its first economic impact report Wednesday. The data covers the 12-month period that ended in October.
"Startups matter to downtowns. Startups matter to the economy," Klein said. "We really want to document how much they matter."
Today American Underground is home to 180 companies at its three sites. Klein estimated that two-thirds of those companies are headquartered in the three facilities, with the remainder based elsewhere but using the sites' co-working and office space.
The companies headquartered at the American Underground locations raised $20.7 million in funding over the past 12 months.
In the fun-fact category, a total of 4,480 slices of pizza were consumed at the weekly Helpfest sessions, which include lunch plus a speaker.
American Underground is in the process of doubling its space at its West Main Street site, which is already its largest site. The additional space is expected to accommodate 40 to 50 additional companies when it is completed early in 2015.
"That space is about 90 percent pre-leased," Klein said.
American Underground, owned by Raleigh's Capitol Broadcasting, offers startups space that is relatively inexpensive.
