Persefoni is an AI-powered carbon accounting SaaS platform headquartered in Mesa, Arizona. It provides businesses and financial institutions with tools to measure, manage, and report their carbon footprint and sustainability data with the same rigor as financial reporting. Its platform supports streamlined carbon footprint calculations, decarbonization strategy development, and audit-ready disclosures compliant with global standards like SB 253, CSRD, ISSB, and CDP. Persefoni aims to simplify complex climate data into actionable insights for organizations pursuing sustainability.
Persefoni was founded in 2020 by Kentaro Kawamori, Jason Offerman, and Kim Stroh, three former Chesapeake Energy executives with strong backgrounds in digital innovation and analytics. Kawamori's passion for sustainability and experience in emissions reporting inspired the creation of Persefoni to address gaps and challenges in climate management and carbon accounting for companies and investors. The founding team continues to lead the company with Kawamori as CEO, Offerman as COO, and Stroh as CDO. The company has rapidly grown to a size of 201-500 employees and built a strong reputation in carbon accounting software.
Persefoni has raised a total of $179 million in multiple funding rounds. Notably, it secured $50 million in August 2023 and an additional $23 million in a Series C round in early 2025. These funds aim to support product expansion, AI innovation, and scaling toward profitability expected in the second half of 2025. Investors include TPG Rise, Rice Investment Group, Clearvision Ventures, NGP Energy Technology Partners, Prelude Ventures, and strategic investors such as a leading European luxury fashion house.
Persefoni’s core product is its Climate Management & Accounting Platform (CMAP), also known as PersefoniGPT, which integrates AI and automation for carbon footprint tracking, emissions data analysis, and decarbonization planning. The platform offers audit-ready sustainability reporting aligned with key regulatory requirements. In March 2024, the company launched Persefoni Pro, a free version geared toward SMBs, which enables them to measure and share their carbon footprint easily. Key features include smart emission factor matching, energy and utility bill management, physical risk modeling, and planned additions like product carbon footprint/LCA capabilities and a self-serve analytics builder.
The company continuously expands its product capabilities by innovating AI-driven features and broadening its compliance and analytics toolkit. Its growth strategy focuses on enhancing its platform to cover a wider range of climate risk management, carbon accounting needs, and sustainability reporting solutions.
Recent and upcoming innovations include AI-powered smart emission factor matching, breakthroughs in utility bill management models, physical climate risk modeling, and development of a product carbon footprint and life cycle assessment (LCA) feature. The platform is also advancing audit controls and building bespoke analytics tools to enable deeper, self-service analysis for users. These enhancements position Persefoni to lead in climate management technology for businesses.
