Wisconsin’s innovation economy has seen at least 19 significant exits over the past six years, according to an Xconomy Wisconsin analysis.
The following list was compiled with data provided by the National Venture Capital Association, which tracks initial public offerings and merger and acquisition activity involving venture-backed companies. Xconomy also consulted the Wisconsin Angel Network and various media reports.
The list is not comprehensive, and it focuses on technology-based companies in sectors like biotech and software. (So, for example, the Wisconsin IPOs in recent years by grocery chain Roundy’s, long-time manufacturer Rexnord, and trucking company Roadrunner Transportation Services, are not included, as they are in traditional industries.)
But the list provides some insight into the high-tech and life sciences exit environment in Wisconsin since the beginning of 2008.
A few key takeaways: The exits demonstrate Wisconsin’s strengths in biotechnology and medical device manufacturing; all but one of the exits were acquisitions (just one IPO); 11 of the companies originated in and around the state capital of Madison, while seven came from the Milwaukee area; and the acquirers were located across the United States as well as Europe and Canada.
Here are the exits, in chronological order of announcement (any exit without a link means it was provided by NVCA or the company):
