What Seismic does

Seismic is a UK-headquartered sustainability consultancy founded in March 2021 by Amy Bourbeau, Paul Lewis, and Andy Schmidt. The firm delivers sustainability advisory services — B Corp certification and recertification, carbon footprinting and Science Based Targets, CSRD/UK SRS/TCFD/ISSB/SECR reporting, materiality assessments, and sustainability communications — to enterprise and mid-market clients. Its differentiated service architecture centres on the Embedded Sustainability Team (EST) model, in which a Seismic team is placed inside a client organisation for 2–3 years to execute the ESG roadmap while transferring internal capability, alongside shorter Project-Based Partnerships for defined outcomes.

The firm holds a distinctive market position as one of only two global partners to B Lab Europe, placing it within the core ecosystem governing B Corp certification. Seismic is itself a certified B Corporation since 2018 with an SBTi-approved net zero target, claims a 100% first-time B Corp certification success rate for clients, and reports a 100% first-time Science Based Targets validation rate. It has worked through 780+ B Impact Assessments and supports 150+ clients on ESG strategy.

Seismic operates from offices in London (at Sustainable Ventures, County Hall) and Luxembourg, serving primarily UK and European clients across Private Equity, Food & Drink, Fashion, Beauty, Health & Pharmaceutical, Professional Services, and adjacent verticals. Revenue is generated through project-based consulting engagements and multi-year EST retainers, scoped and quoted per engagement; pricing is not publicly disclosed and no institutional funding rounds or external investors are reported in the source materials. The firm is founder-led, has expanded its senior team in 2026 with the appointment of a Managing Director and two Director promotions, and operates as a professional services consultancy rather than a software or AI platform.

Core offering

Seismic is a full-service sustainability consultancy that helps businesses embed sustainability into their operations through two primary engagement models: the Embedded Sustainability Team (EST), a 2-3 year retainer where Seismic experts work inside client organizations, and project-based partnerships for focused initiatives. The advisory portfolio spans sustainability strategy, B Corp certification and recertification, carbon footprinting and Net Zero pathway development, regulatory reporting (CSRD, UK SRS, TCFD, ISSB, SECR, EcoVadis), and sustainability communications, delivered across sector specialisms including Private Equity, Food and Drink, Fashion, Beauty, and Professional Services.

Product overview

Seismic is a full-service sustainability consultancy, not a software product company. It does not offer a unified software platform but instead delivers a portfolio of expert advisory services through embedded teams and project-based engagements. The core service architecture consists of the Embedded Sustainability Team (EST), a long-term integrated team model running 2–3 years, and Project-Based Partnerships for shorter-term focused initiatives. The advisory portfolio spans Sustainability Strategy, Reporting and Disclosure (covering CSRD, TCFD, ISSB, SECR, EcoVadis), B Corp Certification and Recertification, Carbon and Net Zero (including SBTi and CDP), and Communications. These services are delivered across sector specialisms (Private Equity, Food & Drink, Fashion, Health, Professional Services, etc.) and complemented by educational content resources (guides, events, and the Seismic Soundbites newsletter). No software product, API, or AI-powered platform is offered.
