TraceAir uses drones and artificial intelligence to provide data and insights that can reduce errors on construction sites. Their platform captures aerial images that are analyzed using AI to detect issues and ensure plans are being properly followed. This can save the $400 billion wasted annually on construction due to errors and changes. Their revenue grew 28% month-over-month to $700k in 2016 and their team of four is led by CEO Dmitry Korolev as they work towards revolutionizing the construction industry with new data and oversight capabilities.
