Kenelm Tonkin is the Chief Executive Officer of Tonkin Corporation, an entrepreneur and business advisor.

Tonkin Corporation is a business outsourcing, data and media company spanning the United States, Australia, Singapore and the Philippines. The outsourcing division specialises in customer service, help desk and technical support services. The data division offers telephone-verified marketing lists, marketing software and data cleansing services. The media division publishes a portfolio of digital B2B properties, produces trade shows and stages training seminars. 

His career is built on deep experience in publishing, trade shows, conferences, seminars and the marketing, data management, outsourcing and software services which enable them to flourish. Accumulated successes have enabled Kenelm to act as angel investor in the private markets and strategic investor in undervalued small-cap public companies.

In 2000, Kenelm entered business life by launching Law & Finance, a boutique conference specialist. That enterprise grew to become a multi-industry B2B information company offering publishing, events and digital properties operating in Australia, New Zealand, Singapore and the United States.

The multinational, multi-division group Tonkin Corporation emerged under his leadership and his achievements were recognized by BRW Magazine and RMIT University: 58th fastest growing Australian business in 2004, 21st largest start-up in 2005, 110th fastest growing business in 2005, 47th in 2009 and 26th fastest growing Australian business in 2010.

In 2007, Kenelm divested to a listed company. In 2008, he relocated to the United States to pursue new business opportunities and was granted permanent residency to the United States for his business acumen shortly after. In 2010, Kenelm spun-off a marketing data management company and, in 2011, parlayed that into the current business process outsourcing offering.

In 2015, he launched List Marketeer, Australia's largest publicly available B2B marketing database as Tonkin Corporation's data division. That same year, Kenelm was appointed to the Advisory Board of LegacyShield, a company offering legacy planning tools through US financial advisory groups.  

Kenelm is an in-demand public speaker and prolific writer on business matters including, from 2011 to 2013, as a featured columnist for the prestigious Australian Financial Review.

Prior to his entrepreneurial career, Kenelm worked in the law, politics and business media.
