Persefoni AI raises $23 million in a Series C extension to support product expansion and reach profitability by late 2025. The company enhances its climate management platform with AI features like smart emission factor matching, utility bill analysis, and anomaly detection. Its tools now serve both enterprises and SMBs, enabling audit-grade carbon reporting aligned with global standards.
Why Investors Bet Big on Persefoni AI in 2025
Persefoni AI has raised $23 million in a Series C extension round announced in March 2025. This latest investment brings the company’s total funding to $179 million. The new round includes participation from both returning and new investors, such as TPG Rise, Rice Investment Group, NGP Energy Technology Partners, Clearvision Ventures, Prelude Ventures, and a European luxury fashion house. CEO and Co-Founder Kentaro Kawamori also contributed to the round.
The company anticipates this capital will support its operations until profitability, projected in the second half of 2025. Entering its sixth year, Persefoni is focusing on refining its AI-driven offerings and expanding its global customer base in the climate reporting and sustainability management sector.
How Persefoni AI Powers the Climate Data Movement
Founded in 2020, Persefoni AI operates a platform designed to assist companies and financial institutions in calculating carbon footprints and preparing sustainability disclosures. Its software supports measurement and reporting for Scope 1, 2, and 3 emissions.
The platform delivers audit-ready data aligned with multiple regulatory frameworks, including:
- California Senate Bill 253 (SB 253)
- Corporate Sustainability Reporting Directive (CSRD)
- International Sustainability Standards Board (ISSB)
- Carbon Disclosure Project (CDP)
These standards are integrated into its Climate Management and Accounting Platform (CMAP), which offers high-accuracy data collection and control for enterprises needing compliance with climate disclosure laws. The platform also enables decarbonization strategy development and supplier engagement.
What Sets PersefoniGPT and Copilot Apart from Other AI Tools
Persefoni’s AI tools include PersefoniGPT, embedded across the platform to support real-time data analysis and recommendations. Copilot, powered by the company’s proprietary large language model, enables users to interact via a chat interface to receive technical carbon accounting assistance.
AI capabilities developed or in progress include:
- Smart emission factor matching
- Anomaly detection for large datasets
- Natural language-based emission factor mapping (pending release)
- Energy and utility bill management
- Physical risk modeling for climate impact analysis
Several of these tools are expected to be launched as commercially available products during 2025.

Why SMBs Flock to Persefoni Pro
Persefoni Pro launched in March 2024 as a free, self-guided offering for small and mid-sized businesses. The tool is tailored for organizations that often form the core of enterprise supply chains. Since launch, it has gained over 6,000 organic signups, exceeding company expectations.
Persefoni Pro includes:
- Core carbon accounting functionality
- Multi-framework sustainability reporting capabilities
- Guided interfaces for users without dedicated sustainability teams
The company expanded Pro to allow broader access to compliance-ready reporting, opening new opportunities for scalable adoption in non-enterprise sectors.
Where the Company Aims to Go from Here
In 2025, Persefoni plans to introduce a dedicated Product Carbon Footprint and Life Cycle Assessment (LCA) module. Additional updates will include:
- A self-serve analytics builder
- Enhanced audit and controls functionality
- Expanded AI modules for cost and time efficiency
The roadmap reflects a transition from enterprise-exclusive tools to hybrid models that accommodate both large-scale organizations and smaller entities.
Why Persefoni AI Becomes a Central Player in ESG and Regulatory Compliance
As climate-related disclosures become more regulated globally, tools that support traceable, standardized carbon data gain traction. Persefoni AI’s alignment with audit-grade emissions tracking and multi-framework compliance positions it as a key provider in the ESG reporting space.
Its platform integrates data that meets investor, regulatory, and internal assurance demands. By automating high-volume calculations and anomaly detection, it reduces both manual workload and the risk of reporting inaccuracies. Financial services firms, in particular, use the software to assess financed emissions across portfolios.
A Platform That Evolves With Climate Disclosure Demands
Persefoni AI continues to evolve its offerings with a dual focus on compliance and technological enhancement. The integration of AI in carbon accounting processes and the expansion into SMB markets signal a strategy that supports adaptability across regulatory environments.
With its latest funding secured, Persefoni aims to further develop commercial-grade AI tools while expanding user access to climate data management at all levels of business complexity.
