Covalence’s expertise is useful for investment management, ESG measurements, ESG news monitoring, reputation management, academic research, and training.

Our main differentiators are: ESG reputation tracking based on media monitoring, artificial intelligence and human analysis; dynamic, granular, news-based data informing about ESG practices (GRI-inspired criteria, UN Global Compact), impact (SDG, SFDR), and materiality (SASB); special skills on the S of ESG; forward-looking reputation score and greenwashing risk indicator.

Corporate disclosures vs news sentiment

The Covalence approach is based on multiple sources of information and considers both the practices of companies and their impact on society and the environment, in the spirit of double materiality.

To produce ratings we compare ESG data publicly reported by companies (disclosure) to online narrative content reflecting the perception of stakeholders such as the media and NGOs (reputation).

This approach allows users to track inconsistencies, monitor changes, and benefit from timely alternative data. The information is delivered in an actionable format to support ESG risk exposure mitigation and long-term value creation.

The co-founders, Antoine Mach and Marc Rochat, firmly believe in the economic value of sustainability: a robust ESG rating reflects a company’s stakeholder trust and its ability to identify and manage relevant social and environmental issues. It is an indicator of corporate management quality, strategic vision, risk management and opportunity creation as well as brand positioning and overall resilience of the company’s business model: elements that are all positively perceived and valued by the markets.
