Persefoni的SEC规则赌注：1800万美元的碳会计与美国强制令的崩溃

做的是什么生意

Cloud software that calculates, audits and reports companies' greenhouse-gas footprints — an 'ERP for carbon data' for enterprises, banks and asset managers.

启动资金：Founded Jan 2020; $101M Series B (Oct 2021, Prelude + TPG Rise), $50M Series C-1 (Aug 2023, TPG Rise), $23M Series C extension (2025) — over $180M total.

起因

Co-founders Kentaro Kawamori and Kim Stroh incorporated Persefoni AI Inc. in Tempe, Arizona in January 2020 as the SEC's climate-disclosure push and EU CSRD drafts gathered force. Kawamori told TechCrunch in Oct 2021 that carbon and climate disclosures would be 'the biggest compliance market since the advent of Sarbanes Oxley and GDPR.'

经过

The bet attracted capital: a $101M Series B in Oct 2021 led by Prelude Ventures and TPG's Rise Fund, then a $50M Series C-1 in Aug 2023 led by TPG Rise with an AI copilot, PersefoniGPT. The SEC adopted its climate-disclosure rule on March 6, 2024 — mandating material climate-risk and Scope 1/2 emissions reporting — then stayed it on April 4, 2024 while challenges were consolidated in the Eighth Circuit.

结果

Still operating, but the core US bet collapsed: the SEC voted in March 2025 to stop defending the rule and proposed its rescission in May 2026. Persefoni pivoted to the EU and California — shipping CSRD-native reporting and SB 253/SB 261 support in 2025, acquiring Diligent's carbon-accounting customer base, and passing 8,000 Pro users.

可借鉴之处

对未定规则的押注就是对政治的押注：1.8亿美元押注美国证交会气候强制令，一次搁置让美国市场一夜消失；生存靠CSRD和加州法规。多元化监管论点。
