Persefoni review and pricing

Modern carbon accounting category leader with the deepest regulatory expertise.

By Persefoni AI, Inc. · Founded 2020 · Tempe, AZ · private

Persefoni is the modern carbon accounting category leader, founded 2020. Raised $50M+ Series B in 2023 led by TPG Rise Climate, with prior backing from Sustainable Future Ventures and Bain Capital Ventures. The product covers Scope 1, 2, and 3 GHG accounting under the GHG Protocol, CSRD readiness, SEC climate disclosure, CDP, TCFD, and ISSB framework reporting. Strengths: deepest regulatory expertise across SEC, CSRD, and CDP frameworks (Persefoni was the first carbon platform to publish public SEC climate-rule readiness guidance), strong audit-readiness with PCAF and Big-Four-aligned methodologies, mature integration with ERP and procurement systems, and PCAF-aligned financed-emissions module for asset managers and banks. Best fit for SEC-registered public companies and large multi-jurisdictional firms with CSRD obligations. Trade-offs: pricing meaningful for mid-market ($60K-$200K/year typical), implementation 2-5 months for enterprise scope, UX is functional but less polished than Watershed, and the financed-emissions module is enterprise-tier only.

Best for

SEC-registered public companies, large multi-jurisdictional firms with CSRD obligations, and banks or asset managers needing PCAF-aligned financed emissions (500-50,000+ employees).

Worst for

SMBs wanting self-serve carbon accounting (Greenly or Sustain.Life better), Workiva-anchored disclosure teams (Workiva ESG fits the existing stack), or Salesforce-anchored firms preferring bundled tooling (Salesforce Net Zero Cloud better).
