McKinsey Global Institute published a few days ago the findings of its study on Open Data, with clearly enlightening results: the existence of open data can improve the provision of services, government transparency, and the possibilities of companies. Something that also can be measured in figures: an increase of $3 billion in the US alone in the value of our societies seven key sectors: education, transportation, consumer products, electricity, fuel and gas, medicine, and the financial sector.

Although the phenomenon of open data is still very early, entrepreneurs can now begin to see the possibilities that can create new projects related to the analysis, processing and use of data. Either in the form of creation of databases, application development, or providing new services to businesses and citizens, what is clear is that shortly a new market to bet on open.

However, the process until the era of big data will be slow, and requires the commitment and understanding of the different elements that make up our societies:

• Governments should work to collect and then give plenty of information that can be worked with them face to generate new applications and solutions for citizens. This implies an exercise in transparency never seen before, but which is increasingly necessary as we think of the future cities. All this without forgetting the central role governments should play in the development of policies to avoid concerns of consumers and businesses in the transfer and use of data.
• Companies act as intermediaries between government information and the provision of services to users based precisely on improving the quality of life of these. So that the process runs smoothly, companies must also be transparent in their information given to governments.
• Citizens will see partly diminished privacy, it is their everyday action anonymously -of which ultimately serves to know how to act companies and governments in creating products and services that fit their real needs. Despite this loss of privacy, will be the main beneficiaries.

In conclusion, we can say that according to the study consulted that the use of open data shows an almost unimaginable economic potential; which tends to an improvement in the efficiency of the companies with new products and tailored services to citizens and a few improvements remarkable about the current era. Translated into greater cost savings for businesses more convenience for users, and greater sustainability in cities.
