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.
