Leadership Team

Mark Bradley

Executive Chairman and CEO

Mr. Bradley graduated from the University of NSW in 1981 and joined IBM Australia as a computer programmer in IBM’s internal computing division. In 1982 he moved to field sales in the role of Sales Engineer until 1984 when he was appointed as Account Manager for a steel-making Division of Australia’s then largest company, BHP.

In 1986 Mr. Bradley was appointed Sales Manager within the mainframe sales division. In their first year together, Mr. Bradley’s team set IBM Australia’s record for mainframe sales by a single sales team in a single year. In 1988 Mr. Bradley formed an international collaboration between IBM Utility customers to jointly build a next generation billing system, and graduated from the Macquarie University Advanced Management Program. In 1990 Mr Bradley graduated from IBM’s Advanced Management Program in Tokyo.

In 1991, after two years in an IBM Headquarters role managing upgrades to IBM revenue management systems in Asia, for which he was awarded an IBM Management Excellence Award, Mr. Bradley was appointed IBM State Manager, South Australia. In this role, he sat on the South Australian Board of the national Australian Quality Awards Foundation, and became a key adviser to the State Government’s Information Technology and Telecommunications industry strategy team, during which time he assisted the State Government to develop its whole of government IT outsourcing strategy.

In 1994, after the global IT industry went into a severe downturn, Mr Bradley elected to have a two year break from IT and was headhunted to establish a direct salesforce for Qantas Airways. Over the following two years Mr Bradley’s new sales team won almost the entire corporate and government customer base from the rival airline, Ansett Airlines, said to be the largest market share shift in Australia corporate history.

In 1996 Mr. Bradley returned to technology joining telecommunications start-up AAPT Limited as Director of Sales and Marketing.

Attracted by the opportunities of the emerging Internet, in August 1998 Mr. Bradley ended corporate life to found his own start-up company, Online Australia Pty. Ltd. This was followed by a second start-up venture, Tralee Software Group, in 2001, when that company invented breakthrough technology for next generation data integration and messaging over the Internet, and applied for its first patent. The technology invented was years ahead of its time utilizing XML-like virtual structures and in-memory processing to automate transformation of data from one format to another, a growing need for internet based electronic commerce.

After the award of patents for the above inventions Tralee turned its focus to commercialising what was clearly a disruptive new technology. In early 2012 a White Paper was commissioned from London-based respected analysts Bloor Research, who hailed the technology as world leading in its class and a necessary component of a future “Semantic Web”.

 Upon receiving the Bloor opinion Mr Bradley commenced a Research and Development program to study this next generation “Semantic Web”, a forward-thinking initiative that resulted in

  • Hiring a Research and Development team
  • The filing of sixteen new patent applications for components of the 2001 inventions
  • The filing of seven patent applications for new semantic technologies
  • The development and launch of a semantic interoperability software platform called Semantiro

In 2013 the company gained approval to become an (unlisted) Public Company and changed its name to Semantic Software Asia Pacific Limited.

The company has now developed an extensive Intellectual Property portfolio consisting of Australian and United States patents, and a world-leading Semantic Computing platform for cognitive computing.

Don Tonkin

Chief Technology Officer

Don joined the Australian Atomic Energy Commission in 1965. He left as a Research Scientist to join IBM Australia after working on centrifuge based fuel enrichment. His last project was the computer modelling of gas flows within the centrifuge.

He joined IBM Australiain 1976 as a Systems Engineer in IBM's Information Systems department responsible for developing internal use software. Don was considered the “go-to man” for any technology challenge that no other IBM Australia Engineer could answer.

In 1985 Don left IBM to establish the IT consulting firm I.S. People, in a partnership with others from IBM and American Express. This company specialised in the migration of whole of company software onto IBM platforms (MVS and AIX) from other environments (NCR, HP, Concurrent etc.). They built the world's first production DB2 relational database site in 1986 for a large Australian Insurance company.

In 1988 Don left IS People and founded ADC Consultants which he managed through to a trade sale to TIER Technologies in 2001. ADC built applications for Telco's, Banks, Insurance, Airlines and heavy industry. It continued the migration of applications across platforms and the setup of major data migrations, both one-off and continuous. The demutualisation of a leading Australian insurance company involved 81 applications across 27 companies on 5 continents (treating Australia as a continent rather than an island) was performed in record breaking time with global-standard setting accuracy.

In 1990 Don set up the DB2 User Group Sydney (DUGS) which later amalgamated with IDUG.

In 1992 he was invited to become an IBM Gold Consultant, IBM’s highest and the most prestigious technical accreditation offered in hardware and software engineering globally; a small group of approximately 40 senior consultants to IBM worldwide.

In 2002 Don founded 'Quipoz', a firm specialising in modernising legacy applications. Quipoz developed software tools for translation of legacy languages to modern OO languages. Using this technology they performed a number of language transformations for whole of government departments, banks, manufacturers and Telcos. This firm was acquired by CSC in 2010.

In 2012 Don joined Semantic Software, as Chief Technology Officer.

Professional Qualifications

1964 Bachelor of Science (Physics & Maths) Sydney University, Sydney, Australia

1972 Master of Engineering (Nuclear) University of NSW, Sydney, Australia

As one of some 40 hand-picked active IBM Gold Consultants world-wide, Don participated in the publication of many IBM technical documents, provided expert input to IBM on core technology directions and product development, and advised IBM on very significant and strategic technology acquisitions.
