A handful of startups made headlines that caused their social media mentions to spike during the week of May 18 through May 24, according to data collected for Inc. by social intelligence company Synthesio.

Synthesio measures the number of times 25 top tech CEOs and 25 prominent startups are mentioned on Twitter and other social networks, as well as in blogs and news site comments. Here are the startups that really got people buzzing:


On May 21, the music streaming service announced that it hit 10 million subscribers and 40 million active users. Following the news of the milestone, fans took to Twitter and other social platforms; on May 22, Spotify was mentioned 41,602 times, compared to an average of just over 26,100 mentions over the full seven-day period. 


The apartment-sharing startup peaked on social on May 21, when it came to an agreement to hand over renter data to New York City's law enforcement officials. The city plans to use the information to identify hosts that are violating city laws by renting out large blocks of rooms through Airbnb. The conclusion of the yearlong dispute accounted for a large portion of the 5,714 mentions of Airbnb on social media that day-- more than double the number of mentions the day before. 


On May 19, the action camera company filed for a $100 million IPO. The news of GoPro's S-1 filing, while not unexpected, generated a large amount of discussion on social. There were 17,281 mentions of the company on May 20, an increase of more than 7,000 social mentions overnight. 

Other Notables

Microsoft CEO Satya Nadella and SpaceX and Tesla Motors CEO Elon Musk also saw spikes in social activity during the week. Nadella was mentioned 2,097 times on May 20, the day his company unveiled the Surface Pro 3 tablet, up from 409 mentions the previous day. Musk, who consistently has been one of the leaders in social mentions among the tech CEOs Synthesio tracks, had his spike on May 23, with 5,046 mentions--more than double his weekly average. This surge followed a series of tweets that Musk himself sent in which he claimed that SpaceX didn't get a Department of Defense contract because he didn't hire Roger Correll, the person who awarded the contract.
