Capitol Broadcasting is expanding its efforts to provide office space and related services for new and emerging businesses in downtown Durham.

The parent of and owner of the American Tobacco Historic District in Durham is leasing two floors of the Self-Help Credit Union building at 201 West Main Street and says the 22,000 square feet of space can house up 50 companies.

Financial details of the agreement were not disclosed.

Capitol has several partners in the project, including the Durham Chamber of Commerce and Duke University, which made “financial contributions,” Adam Klein, chief strategist for the American Underground, told WRAL News.

The new space will be called Underground @Main Street, and 15 businesses have committed to taking space. It is expected to open in April 2013.

Capitol already operates the American Underground at the district, a former tobacco factory. The Underground houses a variety of new companies as well as the economic development group NC IDEA, venture capital firm IDEA Fund Partners, the Council for Entrepreneurial Development, the Triangle Startup Factory and Groundwork Labs, a new business accelerator.

The Underground, which opened two years ago and covers 26,000 square feet, is entirely leased, thus providing some of the reasoning for the expansion.

“The Underground is full with a growing wait list,” Klein said. “We see the strongest demand coming for smaller private offices which is one of the reasons we are expanding to Main Street.”

Eyeing “Transformative and Disruptive Technologies”

Captiol sees the expansion as part of a commitment to help Durham and the Triangle grow, Klein explained.

“Capitol Broadcasting believes its success is tied to the success of the communities in which it operates,” he told WRAL News. “We see the growth of the startup community as essential to the development of a talented, creative workforce that will lead this region for the next 50 years. Our investment in The Underground allows CBC to nurture and support the transformative and disruptive technologies that will create a new and bold future for the Triangle.”

Through programs such as the Bull City Startup Stampede and the Underground, Durham is already home to scores of startups. Numerous technology and other companies already are based at the Underground and across the American Tobacco campus.

Klein said there are no signs that the growth of the past several years shows any signs of changing.

“Stepping back two years, we’ve seen downtown Durham grow from roughly 30 startups to 80 startups and that pace has not slowed,” Klein said. “We believe demand will continue to grow as we invest in the region’s entrepreneurial ecosystem and form a more prominent presence at a national level.

“Of the companies on our waiting list for space @American Tobacco Campus, we see great demand for smaller, private offices for teams that are in product development phase and are early in their life cycle. We want to support entrepreneurs at each stage of their growth and the @Main Street expansion allows us to nurture up-and-coming concepts in a strategic way.”

As part of the expansion, Capitol will now call the Underground as Underground@American Tobacco Campus.

Capitol has several partners in the project, including the Self-Help Credit Union, the Research Triangle Foundation which oversees RTP, NC IDEA, and, which will provide communications hardware to tenants.

NC IDEA, which supports the Groundworks Labs effort, will seek to help startups through a variety of programs.

“Money alone does not drive success,” said Dave Rizzo, the CEO of NC IDEA. “The programming at the Underground @MainStreet will help young companies network their way to important connections and navigate the challenges they’ll face on their journey to success.”
