Abstract
Pioneering, diverse companies are using open data to create innovative products and services that fill gaps in markets, generate income and bring wide social, environmental and economic benefits. We have identified and analysed 270 companies that use, produce or invest in open data as part of their business, through desk research, surveys and interviews about their experiences. The open data companies we studied have an annual turnover of over £92bn, and over 500k employees between them. This shows the scale of open data’s potential value in business.
