ContraxSuite 1.1.1 Release Update

One year ago, we decided to open-source our ContraxSuite analytics platform. Over the past year, the legal tech landscape has continued to shift toward the approach we espouse here at LexPredict. In addition, the shift toward open source has only increased in the past year, with Microsoft’s acquisition of GitHub only the latest evidence of this trend.

The law is destined to play a central role in facilitating and regulating the modern information economy. We believe, however, that in order to propel law into the future, we need to treat the law itself like the production of information. Before we can solve big problems with smart contracts, we need to structure existing legacy contracts. For the past year, we have iterated upon and improved the ContraxSuite software platform in order to aid lawyers, companies, and other legal tech entities in accelerating the pace of improvement and innovation through more open collaboration.
