Investor-State LawGuide (ISLG) was born of the need to provide legal researchers with accurate and comprehensive information at a reasonable cost. With decades of experience in international trade and investment law, Greg Tereposky and Chris Thomas endeavored to solve this problem when they created Tologix, ISLG's parent company. Tologix developed a software platform that efficiently captures and disseminates subject matter expertise to users with the goal of streamlining the cumbersome legal research process.

Using the Tologix software platform, a skilled team of data capture specialists and investment treaty law experts built and launched ISLG in 2011. ISLG's unique ability to map the complex and disparate area of investment treaty law quickly made it a success, and it is currently used by the world's leading law firms, governments, academic institutions and international organizations.

Today, ISLG is powered by a dedicated team of subject matter experts who maintain and contribute value-added material to its research tools. In parallel, Tologix continues to invest in the software platform, and is developing new technologies that enchance users' ability to get the specific information they need, faster.
