After working remotely for a few months, Campbell McKellar realized the value of an office. You can make copies when you need them, there may be a technology person on staff to help with your web connection and human contact can't be understated. But how does one get this when they don't have an office?

That's the problem McKellar set out to solve by founding Loosecubes, a website that allows people to share unused office space.

Though the site's uptake has been solid so far, Loosecubes plans to take the idea even further. In June, the company announced a $7.8 million round of funding -- bringing its total venture-capital tally up to $9 million. See how McKellar is managing to grow while keeping her company's vision on track.
