分水岭赌注：披露规则让碳会计成必买品；1亿美元C轮，估值18亿美元

做的是什么生意

Enterprise software that measures a company's full carbon footprint (scope 1-3), produces audit-ready sustainability reports, runs emissions-reduction programs, and offers a marketplace for carbon credits and clean-power purchases.

启动资金：Series C of $100M at a $1.8B valuation in February 2024, led by Greenoaks; total disclosed funding $239M per CNBC.

起因

Watershed was founded in San Francisco in 2019 by Christian Anderson, Taylor Francis and Avi Itskovich, engineers from Stripe who saw that companies making net-zero pledges had no rigorous way to measure them. At its Series B in 2022 its customers managed an estimated 20 million tonnes of CO2e. The founding bet was that climate disclosure would follow the same path as financial accounting — voluntary at first, then legally required.

经过

The mandate arrived on schedule. The EU's Corporate Sustainability Reporting Directive made 2024 the first year of government-mandated climate disclosure for nearly 12,000 companies, and California's SB 253, signed in 2023, set its first emissions-reporting deadline for 2026. In February 2024 Watershed raised a $100M Series C led by Greenoaks at a $1.8B valuation — the most valuable climate software company — with customers including General Mills, Carlyle, BBVA, Paramount, Block and four of the top six US banks, whose operations it said managed an estimated 479 million tonnes of CO2e, up more than 10x in a year.

结果

Still scaling as of September 2026: in May 2025 Watershed made its CEDA emissions database free as Open CEDA; in October 2025 it launched AI-accelerated SB 261 climate-risk reporting and a Guaranteed Assurance program for SB 253; and in August 2026 it was marketing tools for the law's first filing deadline of November 10, 2026, with 70 of the Fortune 500 among its in-scope customers.
