Mr Double said hosting the event tied in what the collaborative culture Double Farley was trying to create at its Watt St premises.
"We're quite keen to promote that sort of tech and other ways of thinking, so it aligns with that," he said. "The more that people say Whanganui is a smart city, then all you need is an enabler such as an event like this.
"We've just got to take away the barriers."
Whanganui teams had success on an international level last year with the River Hacktivists team named runners-up in the international disaster-mitigation category at the awards night in Sydney. They developed a smartphone app which could match up those who could offer help with those that needed it during disaster recovery.
Another Wanganui team, Foodrate Wanganui was a national finalist for developing a website which allowed people to search a database of eateries to get council health rating and customer reviews.
"It's really quite exciting to see what comes out of it," Mr Double said.
