Case studies


Our client, a startup with global reach, built a successful company with strong impact initiatives, but was ready to take their ESG strategy to the next level. Together, we launched their formal ESG program and governance. Referencing industry standards including SASB, GRI and TCFD, we identified financially material topics, assessed progress and gaps, and prepared them to share sustainability data with investors through disclosures and reporting. To aid future growth, we developed an ESG strategy roadmap, a comprehensive data table for tracking metrics, and their first annual sustainability report. 


Visionary thinking. Systems-based execution. Seeing the forest and the trees, the art and the science of it. We're passionate about catalyzing change within organizations and society to build a more just, inclusive and sustainable future for everyone.

Frequently asked questions

How do you define ESG?

Embedding environmental, social, and governance practices is crucial for building responsible, impactful, and transparent companies and investment strategies. ESG refers to environmental, social, and governance standards used by companies and investors to evaluate risks and opportunities, set goals, and measure impacts and performance across three dimensions: (E) Performance related to topics such as natural resource use, climate risks, and waste, (S) Performance related to treatment of individuals, organizations, communities and society, and (G) Performance related to company leadership and fair, accountable and transparent corporate practices and actions.

How do you structure your engagements?

ESG Launch: Prioritize ESG opportunities and risks — evaluate and share progress with capital providers, customers, and other stakeholders. ESG Integration: Evaluate relevant sustainability topics through a materiality analysis, develop goals and strategies, build ESG management and reporting capacity. Workshops: Introduce your team to ESG best practices and key topics — establish a common understanding and goals.

When is the right time to adopt an ESG strategy?

It’s never too early — or too late — to start. There are practical actions founders and teams can take at every stage. For example, younger startups can integrate ESG expertise into the board or build ESG-related principles into hiring procedures and product development. As an ESG practice evolves, there are additional questions to ask such as: How often do we consult stakeholders to set goals related to relevant environmental, social and governance risks and opportunities (e.g. carbon footprint, diversity and inclusion, board oversight)? Integrating ESG is not a monolithic process, check out the ESG Inquiry tool for more guidance. We’re always happy to have a quick call to get you and your team oriented to the questions you can be asking based on your stage in the journey.

Can you help with disclosures, public filings, and sustainability reporting?

Yes, we support founders and teams in preparing sustainability disclosures for investors, customers and other stakeholders. These include SEC filings, content for presentations and websites, CDP questionnaires, and sustainability reports aligned with SASB, GRI, TCFD, and the UN SDGs, among others. And we make sure you are in a position to report with confidence — that means your ESG strategy is truly integrated into your company processes so that your reporting is both uniquely meaningful and follows industry best practices.
