Driving Change Through Equal Opportunity

At whatimpact, we are champions of equal opportunity. This principle is at the heart of everything we do—from our platform design to our hiring practices and our collaborative approach. We believe that by fostering diversity and creating cross-sector partnerships, we can drive meaningful social, environmental, and economic change at scale.

We believe that data and well-built technology are the cornerstones of transformative change. By leveraging these powerful tools, combined with our genuine passion to make a systemic difference, we have created a platform that delivers efficiency and real impact. 

Our system streamlines the partnership-building process, saving businesses, VCSEs, and public sector organisations valuable time and money, which can then be invested directly in creating tangible impact on the ground—rather than wasted on coordination and administration. We foster a clear understanding of actual impact, enabling the effective allocation of scarce resources to the most impactful interventions.

At whatimpact, we see collaboration as the key to tackling today’s most pressing challenges. Our platform is designed to connect businesses, VCSEs, and public sector organisations in a seamless, efficient way, creating partnerships that are built for social good. By enabling cross-sector collaboration, we foster innovation and accelerate the movement towards a more sustainable and equitable world.

We believe that knowledge-sharing is essential for advancing the global social value movement. Through our think tank work, we provide the market with valuable insights, including guides, white papers, and social content, to share best practices and enhance the effectiveness of cross-sector collaboration. By fostering knowledge-building and innovation, we are helping to drive the global social value movement forward and inspire others to join the cause.

At whatimpact, our team is made up of mission-driven professionals, recent graduates, and expert contractors who work together in an agile and collaborative environment. Over the past eight years, we’ve built a unique, purpose-led concept and delivered exceptional customer service through a combination of innovative technology, a strong service mindset, and unwavering dedication.

We pride ourselves on being approachable and responsive. If you have any questions, please don’t hesitate to reach out via the live chat hosted on our website – a real human will be there to help.
