Atlanta-based Kobiton, a mobile testing platform that allows developers and QA teams to test their apps on real devices, both on their own desks and through the company's cloud-based service, today announced that it has acquired Mobile Labs, another Atlanta-based mobile testing service. To finance the acquisition of its well-funded competitor, Kobiton raised a $14 million extension to its $5.2 million Series A from its existing investor BIP Capital and new investor Fulcrum Equity Partners. As Kobiton CEO Kevin Lee told me, we shouldn't take that as the acquisition price, but it's probably a fair guess that the real price isn't too far off. The companies declined to disclose the exact price, though. Mobile Labs, which was founded in 2011, had raised about $15 million before the acquisition, according to Crunchbase.
