Twitter has been the focus of a number of acquisition talks over the past couple of years, usually as the target of an acquisition by a Google or Microsoft or Yahoo or Facebook.
Twitter has made a few acquisitions of its own, and I was trying, without much success, to find a list of the companies that it purchased, either for the technology that they offered, or for the people that they employed.
Twitter has blogged about the majority of acquisitions it has made, though not all. It’s possible that there are other companies that were purchased by Twitter that I wasn’t able to locate any information on. If you know about any, and you’re so inclined, please let me know about them.
Here are the Twitter Acquisitions that I was able to find:
July 14, 2008
Summize was a 5 member startup based in Northern Virginia, and began with a focus upon sentiment analysis for the Web. They had developed a way of searching and filtering Twitter results that provided significant improvements to those features offered by Twitter itself.
Before Summize developed a way to search twitter, their focus was upon providing sentiment analysis for reviews and blogs on products, people, videos, music, and more. I remember beta testing a blog widget for them back then.
The purchase price for Summize was estimated to be around $15M in cash and Twitter stock
Abdur Chowdhury, who was a Co-founder and the Chief Scientist at Summize is now the Chief Scientist at Twitter.

When the Twitter blog introduced Rael Dornfest to the Twitter community, the focus was more upon what Rael would bring to Twitter than the products that Values of n had developed.
Prior to joining Twitter, he was Oâ€™Reillyâ€™s Chief Technical Officer, and was the force behind Meercat, the first web-based feed aggregator.

The last post on Mixer Lab’s townme blog on October 15, 2009 introduced their GeoAPI which could be used to provide a number of location-based services. On December 23, 2009, the Twitter blog pointed out the introduction of their own Geotragging API a month earlier, and the acquisition of Mixer Labs.

I searched for, but didn’t see a mention of the Atebits acquisitions on the Twitter blog, but a New York Times blog post does a good job of describing Twitter’s Acquisition of Atebits, who was known at the time for the Tweetie apps for using twitter on iPhones and Mac computers.
The last post on the Atebits blog from developer Loren Brichter, “An Amazing Ride,” made the official announcement of the acquistion.
One of the pieces that came along with this acquistion is the assignment of a patent to Twitter, User Interface Mechanics, which describes an infinite scrolling method like the one presently in use at Twitter.

Cloudhopper specialized in building scalable SMS systems, and the incorporation of their technology into Twitter enabled the company to spread across the globe much quicker. And much of that was during the 8 months prior to Twitter acquiring Cloudhopper.
June 10, 2010
Before Twitter acquired Smallthought Systems, they were a client of the company, using their Dabble DB online database to manage internal projects, and their tool Trendly. In More Than Dabbling, twitter introduces the Smallthought Systems team to the Twitter community.

Will Twitter be acquired by one of the major search engines or social networks on the Web sometime in the future?
Will they continue to make acquistions that improve the quality of the services that they offer, and the technical knowledge behind it?
I’ll try to keep an eye out for future acquisitions by Twitter. If you hear of any, please let me know. Thanks.
