Persefoni AI

What Persefoni AI does

Persefoni AI is a private, venture-backed SaaS company founded in 2020 and headquartered in Mesa/Tempe, Arizona, that sells a climate management and accounting platform to large enterprises, financial institutions, and regulated disclosers. The platform is built around a proprietary CO2e Activity Ledger — a calculation-traceable data architecture that underwrites audit-ready Scope 1, 2, and 3 emissions measurement; PCAF-aligned financed emissions for banks, private equity, and asset managers; supplier and portfolio-company engagement; and regulatory reporting templates for California SB 253/261, CSRD, ISSB, SEC, CDP, TCFD, and SBTi. Persefoni holds SOC 1/2 Type II, ISO 27001, ISO 27017, CSA STAR Level 2, and NIST CSF aligned certifications, and is recognized as a Leader in The Forrester Wave™: Sustainability Management Software, Q2 2024.

The product is delivered across two commercial lines — Persefoni for Business (Pro and Advanced tiers with annual subscription, up to 5% renewal escalation) and Persefoni for Financial Services — augmented by PersefoniAI, a natively embedded AI layer that includes a proprietary LLM-backed Copilot, statistical anomaly detection, and the agentic Persefoni Analytics Agent. Revenue mechanics span paid SaaS subscriptions, a free Persefoni Pro tier for SMEs (3,800+ signups by Oct 2024), separately priced California SB 253/261 compliance services, and professional services. Distribution combines direct enterprise field sales, a self-serve PLG funnel, and an ecosystem of channel partners — most notably Bain & Company (powering Net-Zero Navigator), Diligent (Oct 2025 customer-base transition plus equity stake), AWS, Workiva, A&M, Patch, Upright, Connor Group, and Amazon's Sustainability Exchange. Persefoni has raised approximately $179M in cumulative institutional funding across a $101M Series B (Oct 2021) and a $23M Series C extension (Mar 2025), serves 500+ enterprise customers and 9,000+ organizations across 100+ countries, and operates regional entities including Persefoni Japan G.K.

Core offering

Persefoni AI provides a cloud-based climate management and accounting SaaS platform that enables enterprises and financial institutions to measure, disclose, and decarbonize greenhouse gas emissions across Scopes 1, 2, and 3 (and financed emissions for the financial sector). The platform is built on a proprietary CO2e Activity Ledger, embeds native AI (PersefoniAI, Persefoni Copilot, and the Persefoni Analytics Agent), and ships regulatory reporting templates for CSRD, SEC, ISSB, CDP, TCFD, SASB, SB 253/261, and PCAF. It is sold to corporate sustainability teams and to financial institutions' ESG/risk functions, with a free Persefoni Pro tier extending the platform to SMEs and supplier/portfolio data exchange.

Product overview

Persefoni AI operates a unified climate management and accounting platform built around a central CO2e Activity Ledger, delivered through two main commercial product lines — Persefoni for Business (carbon footprint measurement & analytics, sustainability reporting, regulatory and stakeholder reporting, decarbonization management, and Scope 3 supplier engagement for enterprises) and Persefoni for Financial Services (financed emissions accounting & analytics, investor emissions reporting, portfolio decarbonization, and portfolio company engagement for banks/asset managers/PE). The platform is available in PRO and ADVANCED tiers and is augmented by the PersefoniAI embedded AI layer (Anomaly Detection, Persefoni Copilot, and the agentic Persefoni Analytics Agent), the new Enhanced Dashboards module, Net-Zero Navigator (built with Bain & Company), and the SB 253 / SB 261 California compliance solutions. A free Persefoni Pro tier extends the same accounting engine to SMEs and is used to drive Scope 3 supplier and portfolio company data exchange.
