Just into their 20s, Brandon Reynolds and Jarrad Hrotek are set to become multimillionaires with the creation of a video call app that connects celebrities with their fans for a pricetag.
Sociabl??? will provide intimate one-on-one chats with musicians, sportspeople and TV stars for hundreds to the tens of thousands of dollars, with part of the proceeds going to charity.
Already the pair have signed up US entertainer will.i.am, Jimmy Barnes, pop band 5 Seconds of Summer and AFL, rugby and reality TV stars. 
They also in negotiations with the Kardashians, Britney Spears and Miley Cyrus.
Mr Reynolds, 21, said he and Mr Hrotek, 22, came up with the idea while studying in Melbourne three years ago.
"Apps were the big thing, everyone was making a billion dollars and we thought, 'what's something new?'," he said.
"We thought, 'how do you get in touch with a celebrity?'. Well you can't. There is no possible way to do it.
"We thought we'll make a platform that's really easy to use, very simple, you can do it in the back of the car, you could do it in the shower."
Mr Reynolds, who was studying a Bachelor of Entertainment, had been working with 5 Seconds of Summer, while Mr Hrotek was a music producer.
"We had so many girls that wanted to speak to those boys," Mr Reynolds said.
"That's what sort of sparked it for us and we thought will any other celebrities do it."
Although they had next to no money, Mr Reynolds puts down their success to persistence and believing in their idea.
Then 19, he took to the internet and tracked down the contact details of every person on the BRW rich 200 list and pitched them the idea.
He heard back from 20, got interviews with five and managed to get one of them to invest $50,000.
Years of hard work later, the app is now valued at $9 million and they have offices in Adelaide, Los Angeles and London.
It's caught the eye of the Australian government, keen to push innovation, with the Minister for Innovation Christopher Pyne and Opposition Leader Bill Shorten attending its Sydney Launch in   January.
A US launch is to follow in   April.
Confident beyond his years, Mr Reynolds described their success as "surreal".
He knew he was on to something big when during their second round of seed funding, they rejected an offer from a BRW rich lister to own 50 per cent of the company for $2.5million.
"It's crazy, I can't believe it myself," he said.
Former Bachelorette contestant Michael Turnbull, who will cost $500 for a private chat, said he was drawn to the concept because of the charity component.
"For me it's a really good opportunity to connect with my followers and people that supported me with the Bachelorette show," he said.
"Having that charity aspect about it is something that a lot of the celebrities will be attracted to and obviously having that opportunity to talk to their fans as well.
"It's a bit of a win, win really. A lot of people should get on board."
Mr Turnbull called the concept "wonderful" and said he was keen to support the young men.
"He's obviously as very smart and talented young man with a very bright future," he said.
