About
Coolset is a Dutch climate technology company founded in 2021 that provides sustainability management software specifically designed for the requirements of mid-sized European businesses facing mandatory ESG reporting under the EU's Corporate Sustainability Reporting Directive. The platform automates greenhouse gas data collection from connected data sources, tracks emissions reduction projects and their actual impact, and generates structured sustainability reports mapped to CSRD, ESRS, and GRI frameworks. Coolset differentiates by focusing on the full sustainability management lifecycle beyond just carbon measurement, including biodiversity impact, water usage, social metrics, and governance data required for comprehensive CSRD compliance. The company serves companies in the Netherlands, Germany, and broader Europe with 50 to 1,000 employees that are newly subject to mandatory sustainability reporting and need both software and guidance to meet requirements. Coolset raised $14M and has built strong partnerships with accounting and advisory firms that refer clients needing sustainability reporting support. The platform represents the European market's need for all-in-one sustainability management tools that address the comprehensive requirements of CSRD rather than carbon accounting alone.

About
Diligent is a New York-based governance, risk, and compliance (GRC) platform that has become one of the largest providers of board management and ESG software globally. The company serves over 700,000 board members and executives across 90+ countries, and has expanded its platform through strategic acquisitions including Galvanize (compliance and audit management) and BoardEffect (board portal for nonprofits and healthcare). Its ESG module integrates ESG data management with board-level governance workflows.\n\nDiligent ESG enables companies to collect ESG metrics across environmental, social, and governance dimensions, align with major reporting frameworks including GRI, TCFD, SASB, and the UN SDGs, and prepare board-level sustainability reports. The platform connects ESG performance data directly to the board agenda management workflow, allowing directors to review and approve sustainability disclosures within the same secure environment they use for board meetings and governance.\n\nDiligent targets large public companies, financial institutions, and regulated organizations that need to demonstrate strong governance around their ESG programs, not just report data. It competes with ServiceNow ESG, Workiva, and SAP Sustainability in the enterprise segment. Diligent's key differentiator is the integration of ESG with board governance—allowing sustainability to be managed as a fiduciary responsibility rather than a standalone compliance exercise.
