In the United States, businesses operating unmanned aerial vehicles (UAVs) as part of their businesses need authorizations from the Federal Aviation Administration (FAA) and to meet certain other requirements established by the FAA. This FAA link (click here) will take you to a FAA site from which details on this authorization process and other needed requirements can be found.
More than 5,000 businesses have been granted FAA authorizations as of June 2016. The FAA maintains a database of the businesses' names, a brief summary of how the businesses intend to use UAVs, and the date of authorization. This database can be searched at a FAA site (click here to go to the site).
It seems to me that the various technologies, many still developing, in support of current and estimated potential uses of UAVs commercially, offer opportunities for collaborations and vendor relationships between companies. In this regards, the FAA authorization database could be useful in finding potential customers that can be marketed to.
For example, large chemical and energy companies, such as Dow, Eastman, Chevron, Anadarko Petroleum, Duke Energy, Peabody Energy, and Marathon Petroleum are in the database. These companies could well be in need of various products and services provided by companies specializing in UAV technologies and their developments. Applications for UAVs in the chemical and energy sectors are numerous and include inspections, monitoring, maintenance, and surveying.
