He's a 25-year-old millionaire running a global technology company with more than 80 employees – but Harry Sanders' rise to success started with humble beginnings as homeless 17-year-old.

In the infancy of his entrepreneurship, Sanders was sleeping under a bridge in Melbourne and searching for gyms that would let him use their shower.

But through hard work and incredible determination he was able to found and lead Studiohawk, the largest dedicated SEO agency in Australia.

But he also wants others to know the important role that kindness and generosity from others played in his success.

"You can look at it on paper and think, 'It's going from homeless to building a $10 million business'," Sanders told 9News.com.au.

"But I had help from so many people along the way.

"We all need someone to help us."

Sanders was a 17-year-old student at University High School in Parkville when he was kicked out of home and found he had nowhere to go.

He found himself living on the streets of Preston with just his phone and his laptop – armed only with some online skills he taught himself when he was 13.

Once he became homeless, he tried to cancel a business name he'd previously bought to try to get a $80 refund from ASIC so he could afford to live.

It was only when he got the support of social workers and some mentorship from a kind businessman who he met at a free networking breakfast that he decided to try to get the business going.

"They gave me the confidence to go out there."

From there, Sanders worked hard to try and pitch his SEO services to potential clients.
