6fusion, a startup focused on “cloud” computing services, has raised $7 million in new venture funding.

Cloud computing, virtualization and related services are among the fastest growing segments in information technology. And 6fushion is growing rapidly as well.

Currently, the firm has 18 employees. However, with the new funding, 6Fusion expects to add between five and 10 people over the next year in areas of product development, technical operations, and business development.

The company is backed by Durham-based Intersouth Partners, its first institutional investor.

Virginia-based Grotech Ventures led the new round. Intersouth also participated.

The company’s technology focuses on an algorithm designed to help customers manage the metering, consumption and billing of IT services such as in “cloud computing.”

Cloud computing enables firms to utilize servers, bandwidth and other IT services on demand rather than having to purchase hardware and broadband.

6fusion works with clients to provide cloud management software and services.

Recent hires include Richard Martin, a former executive at VMware, as vice president for worldwide sales and business development, and Mark Riedeman to direct software development.

VMware is a global leader in virtualization and cloud technology.

“We are delighted to partner with an experienced and highly successful firm such as Grotech Ventures while continuing to expand our relationship with Intersouth Partners,” said John Cowan, co-founder and CEO of 6fusion, in a statement. “Our business ecosystem is growing at a remarkable pace and investor confidence is further recognition that 6fusion is building a winning business,” he added.

As part of the deal, Lawson DeVries of Grotech Ventures joins the 6fusion board

“There are a lot of startups currently focused on cloud computing, but 6fusion’s ability to federate data center operators and drive value across the IT channel sets it apart,” DeVries said.
