Having sold companies to Google and eBay, taken one company public, and started an investment company (Redstone), Brehm has had the right instinct for future trends and has built multiple businesses to disrupt the status quo.During the early 2000s, he was Executive Directorand Investor at the social network startup VZ-Netzwerke, as well as co-founder of Rebate Networks, which became one of the two largest global e-commerce platforms, positioning Brehm as an expert at not only seeing but also driving a business, during significant global market transitions.One of his more recent ventures is i2x.
