Marc began his career in the financial services sector and started work with Barclays Bank International and then Coutts. He then became a futures trader, and established his own trading Company within London's World Trade Center, helping predominantly German clients execute trades on the US exchanges.

In his early thirties, Marc left the financial services industry and started working in the telecoms space, helping media groups monetize their unsold inventory with a range of value-added Telemedia services.

In 2000, he was first-to-market in the UK with mobile personalization products (logos and ringtones) which went on to become a multi-million dollar business in its own right. A decade later, he launched a celebrity fundraising chat line service which was featured on CNN, ABC and other media outlets.

After many years located overseas, in 2009 Marc moved back to his native homeland, the United Kingdom. Over the years, Marc has built a large and trusted network of contacts throughout the World with whom he now works to help others expand internationally.

Since December 2016, Marc is European Vice President of Gottesman Company, America's largest network of independent M&A Brokers.
