About Signal

Signal has built a world class artificial intelligence platform that turns the problem of information overload on its head! It ingests millions of articles and posts a day from millions of sources, from news media to financial regulation. Using machine learning techniques it has become highly effective at stripping out the information within this content and aggregating it in a single platform. Users can monitor key people, places, events, companies and topics in real-time as well as track changes and measure impact over time, across more content than anyone could ever hope to read! How awesome is that!

It gets faster and more accurate the more data it consumes. With more data points to work with it can show past, emerging and future trends in real-time. It picks up on nuances and combines them the highlight the next big risk, opportunity or crisis that might affect organisations. It makes the unknown, known.

We have an inclusive environment welcoming the skills and experience from many diverse backgrounds, together we have created who we are and what we sell.
