Is this a sign of the big thaw? Or the perfect example of a company that’s able to loosen some greenbacks from tight-fisted venture capitalists because it’s already generating enough revenue not to need it?

Software and services provider ChannelAdvisor has secured $5.7 million in a round of venture capital funding. Boston-based Genesis Venture Partners, L.P., led the round, with participation from online auction behemoth eBay, and Triangle angel investment firms Southern Capitol Ventures, Tri-State Investment Group and The Atlantis Group.

ChannelAdvisor is not a fledgling startup. It has a list of prominent customers, after all, and the company’s president and chief executive officer has said publicly he expected $4 million in revenue in ChannelAdvisor’s first year of business.

“Given the current funding environment, we are especially pleased to have a round of funding larger than our expectations,” Scot Wingo, CEO and president, said in a release.

He added that the cash infusion would enable ChannelAdvisor to deepen its traction in the computer and consumer electronic categories, as well as expand aggressively into others.

ChannelAdvisor’s software links directly to e-marketplaces such as eBay to sell or auction products, giving large retailers and manufacturers a new sales channel to move products. Customers pay an upfront integration fee to connect their e-commerce infrastructure with the ChannelAdvisor network. This automates the transfer of information about inventory, products and pricing, relieving clients of the time consuming process of manually posting and updating merchandise. Clients include IBM, Handspring, Samsonite, Omaha Steaks and Rollerblade.

ChannelAdvisor has undergone a metamorphosis in its short 2 1/2-year life. Founded as AuctionRover in July 1999, by Scot Wingo and Aris Buinevicius, the company was sold in eight months to publicly traded for $166 million in stock. Sixteen months after becoming GoTo Auctions, spun off the division’s assets to ChannelAdvisor in exchange for an 18.5 percent ownership stake, putting Wingo back in control.
