Twitter is apparently on something of an acquisition spree. This week, we already learned that Twitter acquired Madbits, which specializes in deep/machine learning. Earlier this week, it announced the acquisition of CardSpring.

On its earnings call this week, Twitter also announced that it closed the previously announced acquisition of Tap Commerce. Now, it has acquired Mitro Labs, apparently for its talent (via TechCrunch).

The Mitro team will join Twitter in New York, and work on “a variety of geo-related projects,” while Mitro, its multiple user password product, will live on as an open source project with code on Github. The Electronic Frontier Foundation has been helping them in turning it into “a sustainable, community-run project”.

According to Mitro Labs, it will continue to operate as is for the foreseeable future. They had this to say in a blog post:

We want to thank our users, institutional investors (especially Stan Reiss at Matrix and Rich Miner at Google Ventures), and angel investors for helping us build a product that is both secure and usable. We’d also like to thank Twitter for their support as we make this transition.

The EFF discusses its role in the project here.
