About Anmut

In 2018, we set out to solve a big problem. We saw the world-changing power of data being lost because most large organisations don't fully understand the value it creates for their stakeholders, or how to maximise that value. We set up Anmut to map and measure the value data creates, the maturity of an organisation's data management capabilities, and the extent to which data meets their needs.

We are confident that by deeply connecting data with the purposes of organisations, we can revolutionise industries, transform businesses, identify urgent areas for investment, and improve the day-to-day experience for employees. At Anmut, we are on a quest to unlock the potential of data by getting organisations to treat it as a valuable asset. We provide cutting-edge tools and insights to help organisations strategically manage their data assets and achieve their most ambitious goals.
