Buying Gnip shows that Twitter wants to invest more heavily in enterprise services, such as advertising, said Brian Blau, an analyst at Gartner.
Gnip is one of the few companies that has access to Twitter's "Firehose," meaning all the data generated by millions of tweets, every day, in real time. The company then mines the data for trends or information that might be useful to other companies.
The buyout means the two companies will have a much closer relationship and signals where the company sees its strategy, going forward, Blau said.
Graf's experience with consumer products is a good fit for Twitter, said Blau, where Twitter has shown some problems in getting users to stick with the service.
