An online messaging site created in Norwich is set to expand overseas.

Ipatter.com, founded by Andy Fisher in April 2010, gives businesses and organisations a platform through which to broadcast messages.

The company has now announced it is launching the site in Australia and the US with the appointment of two representatives.

Mr Fisher said: 'Developing our presence in Australia and America is an exciting step for ipatter and its users.'

The company has 1,400 'broadcasters' and 700 members signed up, half of which are based in East Anglia, with 5pc overseas.
