What stok does

Stok is a privately held sustainability and decarbonization consulting firm operating as Stok, LLC (Delaware), headquartered at 26 O'Farrell Street in San Francisco with 101-250 employees. Founded in 2010, the firm delivers interdisciplinary professional services spanning ESG consulting, carbon services (including Scope 1/2/3 GHG inventory development and net zero pathway planning), sustainability consulting, energy engineering, building systems commissioning, and end-to-end real estate program and project delivery. Certification advisory spans LEED, Living Building Challenge (including Materials Petal), WELL, and ENERGY STAR programs, with service delivery organized around six industry verticals: Corporate, Multifamily, Retail, Life Science & Healthcare, Data Centers, and Government & Education.

The revenue model is professional-services-based: project and portfolio-level consulting fees on a quote-based, undisclosed pricing structure with no software/SaaS component and no public API or developer tooling. Go-to-market is enterprise field sales targeting Fortune 500 corporates, major real estate owners and developers, and government institutions; named enterprise clients include Google, Meta, Salesforce, BXP, Grosvenor, Rockhill Management, Related, Kilroy Realty, Macerich, Sephora, Subaru of America, and the County of San Diego, with cumulative impact claimed across 750 million square feet, 60+ net zero energy projects, and 1,000+ high-performance building projects on six of seven continents.

Stok's competitive positioning rests on an interdisciplinary expert team combining strategy, management, and technical capabilities; deep specialization in Living Building Challenge and LEED Platinum certifications (including the world's largest LBC Materials Petal renovation at Google 237 Moffett Park); proprietary portfolio-level GHG inventory and decarbonization frameworks; and an industry presence anchored by USGBC partnership and thought-leadership content such as the Stok Signals newsletter. The firm is independently owned with no disclosed venture capital backing, and has used selective inorganic moves — notably the 2019 acquisition of Brummitt Energy Associates — to broaden energy engineering capability.
