Sustainability software leader Persefoni has raised an additional $23 million in Series C financing, bringing its total funding to $179 million, as it doubles down on AI innovation and prepares for profitability in 2025.
Persefoni, a leading provider of carbon accounting and sustainability reporting solutions, announced today the successful close of a $23 million Series C extension. The funding round attracted continued support from existing investors and new strategic backers, including a major European luxury fashion house. Other participants included TPG Rise, Rice Investment Group, Clearvision Ventures, NGP Energy Technology Partners, Prelude Ventures, and Persefoni CEO and Co-Founder Kentaro Kawamori.
Founded in 2020, Persefoni has quickly emerged as a key player in the carbon accounting software space. Its flagship Climate Management & Accounting Platform (CMAP) helps companies and financial institutions measure, manage, and report their carbon footprints with precision and compliance. The platform supports major regulatory frameworks and disclosure standards such as California’s SB 253, the EU’s CSRD, ISSB, and CDP, enabling clients to stay audit-ready and ahead of evolving climate mandates.
CEO Kentaro Kawamori stated that the new funding will support the company through to profitability, expected in the second half of 2025. This latest raise follows a $50 million round in August 2023 and positions Persefoni to continue its product expansion and AI innovation efforts.
“Since our last round, we’ve been pushing the pace of innovation,” said Kawamori. “We launched Persefoni Pro in March 2024—our self-guided, free solution built for SMBs, which are the backbone of global supply chains. The market response has been overwhelming, with over 6,000 organic sign-ups, far exceeding our forecasts.”
Persefoni’s roadmap includes the continued scaling of its AI-based CMAP offering, PersefoniGPT, alongside the release of smart emission factor matching and major advances in energy and utility bill management, as well as physical risk modeling. These capabilities are expected to drive significant efficiencies in sustainability reporting and will be commercialized in 2025.
The company also plans to debut a Product Carbon Footprint/Lifecycle Assessment (LCA) module next year, along with enhanced audit and controls features, and a customizable self-serve analytics builder—tools designed to empower users with greater transparency, speed, and control over their climate data.
“With this funding, we’re not just building software—we’re redefining how enterprises and institutions operationalize sustainability,” added Kawamori.
As regulations tighten and investor pressure mounts for climate transparency, Persefoni’s continued momentum signals a maturing market—and a growing appetite for robust, AI-powered carbon intelligence.
