Decades of experience. One clear mission

OpenCorp was built by investors, not executives. Over 20 years, we’ve grown from helping family and friends to a national team of 100+ property professionals guiding thousands of Australians to living life on their terms.

We know what works, because we’ve done it ourselves. And we’re here to help you do the same, with clarity, confidence and the right strategy at every step.

A shared goal

Al Lewison and Cam McLellan meet while stacking shelves at Safeway. They’re young with a big goal: to create wealth through property. They don’t yet own an investment property, and there’s not much educational info out there, but they commit to learning the process.

Property one

Steve Lewison takes his sons, Al and Matt, to meet his bank manager. The brothers have saved $20K and want to buy a small two-bedroom unit in an outer suburb of Melbourne for $120K. This is their first investment property and very first loan, they haven’t even held a credit card.

On the path

Al buys property two: an old house in Bayswater VIC. Cam buys the house two doors down. It’s Cam’s first property and he’s saved hard for the deposit, selling his car and cashing-in overpaid super. While their friends are out partying, the duo knuckle-down to save their money and plan their next step.

Developing experience

The team is onto something. Al and Cam replicate their success by delivering sophisticated property developments in Melbourne. Matt moves up the ranks with his employer as GM of Peet QLD, responsible for over $1B in development. Steve joins the team as a passive investor.

A methodology emerges

Matt moves to Brisbane to deliver large scale property developments for his employer. The trio start investing across two cities. As Brisbane’s growth escalates, a clear method emerges, enabling them to pick the best property every time, regardless of the market cycle.

A business is born

The team secures 17 laneway lots in Brisbane, bringing contracts, valuations and rental appraisals together and officially launches Open Corporation.

A singular focus

Friends and family ask for advice; Matt returns to Melbourne to lay the foundations for a dedicated education business.

Mentoring passion

Al and Cam sell their Telstra business to devote 100 % of their time and energy to Open Corporation. Taking a special interest in developing investor education, they are able to share their deep experience with clients, helping their clients to become better investors.

BRW Fast 100 success

Open Corporation debuts at #13 2014 on the high profile BRW Fast 100 list and features again in 2015 in #6 place.

That same year the organisation rebrands to OpenCorp

Delighted customers

OpenCorp expands its lending services launching OpenFinance, leveraging 12 years of broking experience

Hitting our stride
