Microsoft Ventures' first investments: A who's who

Microsoft created a new ventures arm just over four months ago. As of October 4, Microsoft Ventures has invested in 13 companies, officials said today. Microsoft and the Series A to Series D startups in which it has invested to date are not disclosing the amount Microsoft is investing in each of the companies in its portfolio. But Microsoft has created a new Microsoft ventures site listing the companies it is backing. There are three additional companies in Microsoft Ventures portfolio which haven't been announced yet, officials said.
