Southern Capitol Ventures is betting that weddings will continue to be big business and that a website has a business plan that will profit from linking couples with service providers.

WeddingWire, which is based in Bethesda, Md., said Wednesday that it had closed on an investment from Southern Capitol, which is based in Raleigh. It was the only investor.

The amount of the investment was not disclosed.

“We have watched the team at WeddingWire execute on their vision over the last 5 years bringing more efficiency to the wedding industry,” said Jason Caplain, co-founder and general partner at Southern Capitol Ventures, in a statement. “This is one of the very few companies nationally that has successfully solved access to local merchants.”

WeddingWire used some of the funding to acquire ProjectWedding from the online social meeting site eHarmony.

The company also said it has signed partnerships with Conde Nast, which operates Brides.com, and Internet Brands, which owns Weddingbee.com. It also is expanding a deal with Martha Stewart Living Omnimedia, operator of MarthaStewartWeddings.com.

“We have a long-term relationship with the team at Southern Capitol Ventures,” said Timothy Chi, chief executive officer of WeddingWire. “SCV brings a strong track record of working alongside entrepreneurs, deep, meaningful industry contacts, and a clear alignment with our vision for building WeddingWire.”

WeddingWire connects couples with more than 100,000 vendors, which have been reviewed. The site also offers planning tools and checklists.

Service providers work with WeddingWire for marketing services, networking, social media, mobile customer access and search engine optimization.

Capitol Broadcasting, the parent of WRAL Tech Wire, is an investor in Southern Capitol.
