OneSource Virtual, an Irving technical services firm, has wrapped up a friends-and-family round of financing worth about $6 million, according to its chief executive officer. Roughly 60 percent to 70 percent of the capital came from the family of OneSource’s CEO,  Brian Williams. The 20 or so investors in the round acquired a “very minority stake” in the business, Williams added. The financing is supporting OneSource’s growth, Williams said. Since starting the equity raise in the last year or so, OneSource has gone from 120 employees to closer to 205, Williams said. He expects to add another 100 in the next 12 months. OneSource’s revenue grew 2,872.82 percent between 2009 and 2011, putting it at the top of the recently announce Fast 35 list.
