Aquis Exchange is delighted to announce the appointment of John Greenan as Director, Technologies: responsible for leading the sales and contracting activities for the company’s market-leading proprietary exchange infrastructure technology and services.
Greenan relocates to London for the role, and draws on over 20 years’ experience as the CEO of Alignment Systems: a consultancy providing global electronic trading expertise and strategic insight to investment banks, asset management companies, hedge funds, stock exchanges, interdealer brokers, trading venues and digital assets businesses. During this time he has worked on four continents and driven adoption of electronic trading over multiple asset classes. As a member of the FIX Trading Community Global Technical Committee, Greenan is a leading and respected voice on industry technical standards and their application, including for 24x7 trading: an area in which Aquis is an industry leader.
“Aquis is delighted to have John Greenan on board at a pivotal time for our Technologies business,” said Adrian Ip, Chief Strategy Officer, Aquis Exchange.
“With several significant client wins in recent years, Aquis has broad recognition by the market as a leading provider of cutting-edge, cost-effective, low latency exchange infrastructure. We run our own markets on Aquis technology, as well as now providing technology to other major exchanges, national banks and other providers. John’s expertise will be a great asset in helping us to design and provide optimal technology solutions for clients both existing and potential, and to continue to cement our position as the technology provider of choice for today and tomorrow’s markets.”
John Greenan, Director, Technologies, said:
“I am thrilled to be joining Aquis at such an exciting time for the company. Within the industry, Aquis is regarded as an excellent choice of technology vendor – not just for its leading matching engine and frequent product innovation, but also for always going above and beyond in the service and solutions that the team provides to their clients.
While consulting I conducted extensive research for a search and selection and selected Aquis to provide a genuine 24x7 capability for a Singapore-based digital exchange. In a manner akin to the great Victor Kiam, I liked the product so much I joined the company! I am looking forward to progressing a strong existing sales pipeline and to working with such a great team.”
