Artificial intelligence and alternative data

Artificial intelligence and alternative data

We use technology and AI, combined with our 200+ strong team of ESG analysts, to extract investment-relevant insights from unstructured data. Machine learning and natural language processing help us increase the timeliness and precision of data collection, analysis and validation to deliver dynamic content.



Alternative data helps minimize reliance on voluntary disclosure to deliver key insights. Alternative data sets are information about a company published by sources outside of the company. We use them to:


  • Deliver insight not captured with voluntary company ESG disclosures
  • Identify risks and opportunities not commonly disclosed in traditional data sources
  • Create innovative metrics
