Twitter has agreed to acquire Smyte, a San Francisco-based online abuse management company that specializes in safety, spam, and security issues. Twitter says Smyte’s technology and mission are aligned with its focus on “improving the health of conversation on Twitter.” Financial terms were not disclosed.

In a statement on the Twitter Safety blog, the company said, “The Smyte team has dealt with many unique issues facing online safety and believes in the same proactive approach that we’re taking for Twitter: stop abusive behavior before it impacts anyone’s experience.”

It added, “Smyte’s products will help us address challenges in safety, spam and security more quickly and effectively. Their review tools and processes will be powerful additions to our own tools and technology that help us keep Twitter safe.”

Smyte was founded by former Google executives and engineers with backgrounds in spam, fraud and security in 2014 to sell “Trust and safety as a service.” Its clients include Indiegogo, GoFundMe, TaskRabbit, Zendesk and other, but Twitter told Techcrunch it shut down operations with those customers as it did not buy it for profit, but for its talent and intellectual property.

Twitter said it will integrate the Smyte technology in its systems and operations in coming months.

Shares of Twitter Inc. (NYSE:TWTR) were down 1.5 percent at $45.42 in mid-day trading Thursday morning, but are up 153 percent over the past 12 months.
