About Black Swan Data

We are a Data Science & Creative Technology Company. We help our clients find insights and solutions that change the way they think about their business. We analyse consumer behaviour, then build cutting edge technology to create better outcomes for our clients. 

Our name is derived from an ancient assumption that all swans were white, until a European explorer travelling to Australia in 1697 saw some black swans and had what is known as a ‘black swan moment’.  2 years after launch, we’re already 120 people and now have offices in Waterloo, Exeter, New York, Hungary, California and Cape Town.
