Helping Create Change that Matters
about us
Open Cities helps organizations to become more effective as they work towards the 2030 Sustainable Development Goals.
Our work spans the macro and the micro, the conceptual and practical, prompting change and managing change, the beginning and the end of projects. We work at local and at national levels, in the UK and around the world. Some of our work spans multiple countries and is commissioned by international organizations like the World Bank.
Our standards match those of the world's very best organizations. We know that because over the years we have ourselves worked in and excelled at the heart of many blue-chip organizations. Our commitment is to deliver at the highest possible standards - at affordable prices.
We use AI judiciously - not as a replacement for judgement or human decision making, but as an aide. See our blog on 'Keeping Evaluation Human'.
