Side-by-side comparison of AI visibility scores, market position, and capabilities
Greenly is a carbon accounting platform helping SMEs and enterprises measure, reduce, and offset their greenhouse gas emissions with automated data collection and expert guidance.
About
Greenly is a French climate tech company founded in 2019 that has raised over $52M to make carbon accounting accessible to businesses of all sizes. The platform automates greenhouse gas inventory preparation by connecting to accounting software, banking data, and operational systems to collect activity data, then applies emissions factors to calculate Scope 1, 2, and 3 emissions across the full value chain. Greenly targets small and mid-sized businesses that lack dedicated sustainability teams, providing both the software and access to certified carbon experts who guide customers through measurement, reduction planning, and reporting. The company competes with larger enterprise-focused platforms by offering a faster, more automated onboarding experience with expert support that makes carbon accounting achievable for companies with limited resources. Greenly serves over 2,000 customers across Europe and North America spanning retail, hospitality, professional services, and technology. As corporate ESG reporting requirements expand under frameworks including CSRD in Europe and SEC climate disclosure rules in the US, Greenly has positioned itself as the accessible carbon accounting solution for companies beginning their sustainability reporting journey.

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.
