Executive search and leadership consulting

We believe that global sustainable development is the most important challenge of our time. Collective action between corporates, civil society and government is crucial. Collaborative leadership is essential to connect business strategy to these global priorities. We find the people that make this happen.

Operating internationally from our offices in London and New York, we provide recruitment, research and advisory that enables organisations to change the way they do business globally.

As a boutique search firm, we are at the heart of a distinctive network of people and organisations driving the sustainability and development agenda.

We partner in country and at group level with corporates, strategic advisory, multi stakeholder initiatives and the sustainable finance community across EMEA, Americas and Asia Pacific. 

Not business as usual

Why this matters

There is a clear opportunity for global organisations to do better business by driving progress towards the Sustainable Development Goals.

We support our clients to deliver on their sustainability ambitions by recruiting leaders and building impactful teams and boards. These are crucial hires to drive sustainability strategy and development innovation to scale impact; across poverty alleviation, energy & climate change, deforestation and conservation.

Our clients and candidates choose us because we understand that collective action is crucial to achieve sustainability ambitions for an equitable future. Our network and track record reflect this.  

We successfully partner with the private sector, and their influencers and changemakers. It is at the heart of this community of innovation across the private sector, government and civil society that we work.
