Strategy for

Your company is built around the purpose of having a positive impact?

We support mission-driven companies to scale.

We believe that our planet is a gemstone: it and its inhabitants need care and protection.

Our goal is to support companies and projects with the purpose of improving humanity’s impact on the world, and together contribute to human legacy.

We are ex-Big 4+ (PwC, Deloitte, EY, KPMG, McKinsey, BCG, …) who transitioned with the purpose of making a positive impact through our work.

With our network of international agencies, they support you to scale your impact:

  • identify new opportunities;
  • build a plan;
  • find the resources to pursue them.

Scale-ups, private SMEs, or NGOs who wish to have the fresh look from an external advisor for a project or regular support, we are committed to your sustainable development in the context of your industry’s trends.

Which companies, organisations, initatives, have a positive impact on the world with the decision that they take?

Following the “2017 Annual Impact Investor Survey” by The Global Impact Investing Network, impact projects have “the intention to generate a measurable, beneficial social or environmental impact alongside a financial return”.

How to scale your impact:
