Director Jack Buser hit back against scepticism for the project and insisted that it has done well for the platform holder.
"Home is new. We're doing a lot of really new stuff that I think the industry is still wrapping its head around," he told Gamasutra.
"We're seeing a lot of innovation in the space, and some of us have hit success. The proof is in the pudding. With numbers like we have, it goes without saying that Home has been a huge success for our company, something that we have been very proud of."
Buser explained that the average user session is 70 minutes, with 85% of users returning back to the service more than once, and has currently clocked over 14 million users worldwide.
It was added that the micro-transaction business model is "quite profitable" for the service.
PlayStation Home entered open beta in late 2008 and is free to download for all PlayStation 3 owners.
