A world first application connecting residents and facilities managers in high density living accommodation, has gone live in South Australia and is expected to have more than one million users by 2023.

The application, which is called Communitilink and is now available on the App and Play stores, has been developed by 21-year-old Lead Software Developer Joshua Marcus, in collaboration with Aaron Smedley and Tom Welsby.

Joshua, who completed a Diploma of Website Development at TAFE SA in 2015, said the unique software application integrated across multiple platforms such as interactive noticeboards and touch screens, as well as mobile applications.

He is sharing his story this week, in line with Entrepreneur’s Week (9-13 July) – an event which showcases South Australia as a place of creativity, innovation and enterprise.

“CommunitiLink was born out of a need for facilities managers of high density living complexes to be able to communicate with their residents more easily, securely and effectively,” Joshua said.

“At present some of them are still using costly methods such as mail and letterbox drops to communicate with their residents with the immediate notification of an incident or urgent alert almost non-existent.

“The application offers a diverse and completely customisable array of management and owner specific information such as building policies and procedures, one-off notices and committee newsletters.

“The application also includes a maintenance reporting portal, the ability to receive push notifications and send SMS emergency alerts as well as the functionality to remotely book building facilities at the click of a button.”

Joshua and the CommunitiLink team won the top prize at the 2017 Australian eChallenge, run by the University of Adelaide’s Entrepreneurship, Commercialisation and Innovation Centre – winning $10,000 and a day at Microsoft’s Adelaide base.

The eChallenge is an annual competition for early stage entrepreneurial ventures with teams pitching their unfunded business ideas to potential investors.

Joshua said the CommunitiLink application also encouraged residents to engage with one another, share stories, sell and swap items and support local businesses.

“CommunitiLink also provides a rewards platform directed at local businesses who can promote their products to CommunitiLink members within a set radius of their business” he said.

“Not only will this platform increase local business revenues and user engagement but it ultimately provides the bridge between the outside economy and building residents that has been needed for so long.”

He said the application had the potential to be rolled out across 10,000 buildings and more than one million users over the next five years in Australia alone, with plans to target the global market in the US in the near future.

“I learnt all the fundamentals of web development during my TAFE SA course – I have just built on those skills and knowledge to be where I am now,” Joshua said.
