Here’s a closer look at that $1.1B Ed Tech venture capital financing in 2012, data courtesy of CB Insights, an information services firm tracking investment in technology companies. The list includes larger education companies, both private and public, that have been most active in both acquiring and investing in emerging, privately-held edtech companies. Based on M&A and financing data since 2010, London-based publisher Pearson tops the list with 15 acquisitions or investments in edtech companies followed by Providence Equity Partners-owned education software provider Blackboard. Rounding out the the top three is Macmillan Group which acquires and invests in edtech companies through two separate arms – Macmillan New Ventures and Macmillan Digital Education. Six of the top 10 are publicly traded education companies as can be seen in the accompanying table. This list contains only education companies involved in acquisitions and investments and does not include private equity firms and others who may be invested in or acquiring in edtech.
