We are bringing together the best minds in process, engineering, computing and chemistry to develop solutions to address some of the world’s toughest challenges – water and energy scarcity and sustainability. Over the past few years there has been an explosion in unstructured data across industry driven by affordable sensing technologies and adoption of analytical instrumentation. This sudden increase in data has resulted in industries spending significant amounts of time collecting, organizing and analysing content and very little time driving value with the data.
