"You're not having to pour more concrete," said Gebbia.
He and a roommate founded what has grown to be a US$31b high flyer of the shared economy when they pulled an air mattress out of a wardrobe and let it out to cover a rent increase.
"That's when we became entrepreneurs."
New Zealand had embraced Airbnb, he said.
There were close to 34,000 listings here, up 71 per cent in the past year with 700,000 users. Guest arrivals were up 136 per cent to 1.3 million.
The relationship with the hotel sector had matured and there was room for both. Around he world occupancy in traditional accommodation was high and yield was strong while Airbnb properties were also thriving.
The company was looking at ways of expanding beyond accommodation and local experiences some hosts offered.
"Our big idea is that we would like to offer the whole trip," he said.This would be a seamless, uncomplicated experience. Asked how this could fit into how airlines operate, Gebbia said hat he could not divulge any details.
He stays in Airbnb places when he's travelling, his favourite with a Buddhist monk in Japan. He's recently made available temporary space in an apartment in San Francisco under an emergency accommodation for disaster victims or refugees.
He said he was too busy to think about the wealth he's reported to have.
''I'm very focused on the company, my life hasn't changed - you ask my friends and family.''
