Sinzer is not your average consultancy firm. Over the last decade we have become a thought-leader in the impact sector, and our no-nonsense approach to strategy, reporting and consultancy has helped transform organisations of all shapes and sizes. We are committed to truly maximising an organisation’s positive impact on our planet and society.

We work with with all sorts of organisations; from global NGO’s to businesses, and from investment funds to local councils. So we know our way around municipalities, boardrooms and factories, and understand they all have their own velocity and culture. But the one thing our clients all have in common; they’re done talking and want to make a real difference.

Sustainability, equality, climate change, poverty and health have become hot topics, and awareness is greater than ever. But as impact experts we are also critical. We see it as our mission to move from awareness to action. We need to build a new future proof system, where every organisation, industry and sector has its own role and responsibility. We envision a society in which all their products, services, and activities contribute to a better world.  So if green- or social washing is what are looking for, we kindly refer you to our competitors. If you want to find new opportunities to be more impactful, look no further.Part of

To expand our own impact, we joined forces with Grant Thornton in 2019. This means we are now part of a global network of independent accountancy and consultancy organizations with over 50,000 professionals. This win-win deal allows Sinzer to further professionalize and mainstream impact as a full service, and helps to close the gap between doing good and doing business. Furthermore, we feel bringing the fields of accounting and impact closer together holds a lot of potential: applying similar principles and giving as much weight to your non-financial value (impact on people and planet) as to your financial value, will accelerate the transition to an ‘impact economy’.
