Twitter has announced the acquisition of Smallthought Systems, manufacturers of the Dabble DB online database and the web analytics filter tool Trendly.

It claimed that it used Dabble DB to track and share information about its projects internally and while it has moved project management tools in-house, it maintained a relationship with Smallthought Systems. It also said that it was one of the first to try the Trendly tool that helps websites distinguish signal from noise in their Google Analytics data.

Twitter said: “Therefore, it is with great pleasure that we announce the acquisition of Smallthought Systems. They have joined our analytics team and will focus on integrating ideas from Trendly into our current tools and building innovative real-time products for our future commercial partners.”

Dabble DB co-founder and CEO Andrew Catton said that it was ‘joining forces with our friends at Twitter', saying: “Obviously this represents a new chapter in the life of Dabble DB, both for us as a team and for the product itself. We'd like to assure you that, for now, we will continue to provide our software and technical support to current Dabble DB customers. However, we will be disabling new account signups effective immediately.”

Meanwhile AVG Technologies has announced the acquisition of security software distributor Walling Data. The company will be integrated into the AVG US and global team.

Luke Walling, founder and president of Walling Data, said: “I am excited about joining the AVG Technologies team. Since founding Walling Data 16 years ago, I have concentrated on providing unique solutions to common problems, wrapped in the best possible customer service and support. We have been strongly committed to the success of AVG since we first began working together, and I am excited to reaffirm that commitment by becoming part of the AVG family.”
