About ESG Book

ESG Book is a global sustainability data and technology company established in 2018. It was originally incubated as a subsidiary of the Arabesque Group, a financial technology firm, and was formerly known as Arabesque S-Ray before rebranding in May 2022. The company was founded by a global alliance of financial institutions and investors to serve as a central source for accessible and transparent corporate sustainability information. In June 2022, ESG Book secured $35 million in a Series B funding round led by Energy Impact Partners (EIP), Meridiam, and Allianz X to advance its technology and expand its global footprint. The company is led by CEO Justin Fitzpatrick, a veteran in business software and fintech who previously co-founded companies like FullCircl and DueDil.

The firm operates in the growing ESG data market, estimated to reach $5 billion by 2025, by providing data and technology solutions to financial institutions, investors, and corporations worldwide. Its business model centers on offering a cloud-based, Software-as-a-Service (SaaS) platform that makes environmental, social, and governance (ESG) data accessible, consistent, and transparent. Revenue is generated from premium services, including data analytics and tailored solutions, while companies can use the platform for free to disclose and manage their ESG data in real-time. This approach enables clients, which include major financial organizations like Bloomberg, Citi, Deutsche Bank, and HSBC, to integrate sustainability insights into their investment decisions, risk management, and regulatory reporting.

ESG Book's core offering is a comprehensive data platform covering over 50,000 companies. The platform provides a wide spectrum of products, including raw ESG data, company and portfolio-level scores, climate data, and analytics tools. A key feature is its framework-neutral design, which allows corporate data to be mapped across various global standards and regulations such as GRI, SASB, and TCFD simultaneously. The platform integrates data from corporate disclosures, with over 200,000 available, and uses machine learning to scan over 50,000 news sources for real-time controversy monitoring. This dual approach allows for a holistic view of a company's sustainability performance, combining self-reported metrics with external news-based analysis to support more informed decision-making for capital allocation.
