About Us

Charlotte Cornish and Anna Grey are strategic research and evaluation consultants each with more than 25 years of practising market and social research for public, private and third sector organisations.

In 2015, they established Cornish and Grey, a social enterprise providing evaluation and impact strategy support to social purpose organisations.

They work with funders, grant makers, capacity builders, umbrella organisations, charities and social enterprises to help develop simple and practical impact or measurement strategies so they can become more effective and ensure that limited funds are spent where they make the most difference.
