Founder / CEO
Founder and CEO of the Proactiv Group, Roy Mellon draws from years of cross industry experience in specialised payroll, Human Resources and business systems. It’s his in-depth knowledge of the processes and intricacies of payroll, and his understanding of the continual frustrations payroll personnel have with their current payroll systems that led him to design Definitiv.
Tyson has brought a wealth of project management and technical experience to Definitiv. As both Senior Software Engineer and Technical Director he has led the development of specialised application software on a number of projects. In more recent years, Tyson’s technical capabilities and commercial awareness has led him to designing and developing online and mobile applications to meet the needs of new and emerging markets.
We are based in West Perth, Western Australia. Feel free to drop in for a chat about how Definitiv works.
