ValueCo

ValueCo is a Paris-based software company that collects and standardizes the proprietary ESG (environmental, social and governance) ratings that institutional investors produce internally, then turns them into an aggregated, anonymized view of how the market values a company's sustainability performance. The platform is sold to asset managers, institutional investors and corporates, and is positioned to help issuers understand what investors think of their sustainability profile, what drives those opinions and where the perceived weaknesses lie.

According to company statements, ValueCo aggregates the standardized opinions of more than 47 asset managers representing portfolios exceeding $9 trillion, covering more than 30,000 companies — both the roughly 10,000 in which contributors have invested and the roughly 20,000 they declined to invest in for sustainability-related reasons. Management frames the product as closing a feedback loop that normally runs only from companies to investors, giving issuers systematic feedback with which to steer sustainability strategy and enabling explicit pricing of sustainability-related risk and opportunity.

Founding story

Chief executive Mariem Mhadhbi is a trained engineer who studied finance and spent more than 13 years in financial markets, beginning in credit structuring at ING in New York and equity derivatives in Brussels, then moving to the sale of structured products and institutional consulting. She co-founded the company with data scientist Mathieu Joubrel, co-author of several books on sustainable finance; press accounts date the founding to 2022.

Business model

ValueCo operates a SaaS platform. Asset managers contribute their internal sustainability assessments on a voluntary basis and receive in return benchmarking of their assessments against peers and access to research from academic partners including MIT; corporates and investors are served with market analyses built on the aggregated, anonymized data.

Software-as-a-service subscriptions to market analytics and ESG perception data for asset managers, institutional investors and corporates.

Traction

The web platform launched in April 2023; by late 2024 the company reported partnerships with more than 40 banks and asset managers, and by 2025 said it aggregated assessments from more than 47 asset managers representing over $9 trillion in portfolios. Customers cited include LVMH, Thales, ABN Amro and Bank of America.

Latest developments

In May 2025 ValueCo took second prize in the Challenge Innovéa run by Groupe Caisse des Dépôts, and in June 2025 it won a Tech For Change award at VivaTech in Paris. Management has described plans to expand the team, research capabilities and technical infrastructure following its funding.
