CB Insights, a New York-based analytics software that helps companies make technology decisions, has acquired Blockdata, a Netherlands-based company that tracks the global blockchain economy. CB Insights will open an office in Amsterdam, while Blockdata will both remain a stand-alone product with its own team and also be available to CB Insights clients. Financial details of the deal were not disclosed.

Blockchain has “gone from something that was considered possible or probable to something that is now practical,” says CB Insights co-founder and CEO Anand Sanwal. He added that his team has watched customer activity around blockchain accelerate dramatically over the last eight months.

Hence the acquisition. The Dutch startup built a market intelligence platform that helps financial institutions, governments and enterprises identify the most credible use cases of blockchain and pinpoint the best companies and projects to work with.

As the story goes, the conversation between the companies was kicked off by a cold email and came together (online) in less than three months. This is CB Insights second acquisition, hot on the heels of their July purchase of the assets of Dow Jones VentureSource. Both M&A deals are bringing proprietary data in house.
