Twitter has announced Niche, a startup that helps content creators and social influences on the microblogging network meet advertisers.
The deal was announced after the markets closed Wednesday.
Financial terms of the deal were not announced.
Niche offers software and services, in the most traditional sense possible. It provides free analytics and tools to content creators -- influential tweeters and Vine video makers to name just two -- to help figure out what works and what doesn't. At the same time, it also helps social media stars and content creators make money by working with more than 100 brands and agencies.
It comes on the same day the startup announces a milestone of 6,000 content creators in its portfolio.
Twitter said on its blog it hopes the acquisition will continue to "inspire people to create great content."
What's next? Niche says it'll provide "more tools, more platforms, and even more opportunities to team up with the best advertisers in the world."
Twitter ($TWTR) closed the day up 2.7 percent.
