To start off our 2012 sessions, we hosted Christo Davel, founder of 22Seven, a financial service that helps you manage and monitor your spending. The talk revolved around our irrational behaviour, the user experience and design. Christo provided some great insight into the aim of this service. Take a look at what he suggests is the key to financial success. Once again, a big thanks to Deloitte, Backsberg wine, Nokia and Channel Mobile.
