Signol is a software product that brings behavioral science to captains and pilots, creating commercial, environmental, and social value at speed. Our software is a communication and feedback platform that continually optimizes individual operational efficiency, using a combination of behavioral science and data analytics. We connect individual performance to operational data, and motivate our end-users to improve their performance in small ways, leading to a compound reduction in fuel use and emissions. Our first use case was in aviation, where our research successfully saved Virgin Atlantic $6.1 million in wasted fuel and abated over 24,000 tonnes of CO2 emissions over 8 months in a world-first application.
