Google is launching a fund devoted to nurturing promising tech startups in Europe. The Silicon Valley-based Internet titan said Thursday that it is setting up a Google Ventures office with a mission of backing European entrepreneurs and putting $100 million into its account as a start. Our goal is simple: we want to invest in the best ideas from the best European entrepreneurs, and help them bring those ideas to life, Google Ventures managing partner Bill Maris said in a blog post. Google Ventures launched five years ago in the United States and blends cash backing with access to the tech titans talents when it comes to engineering, design, marketing and other aspects of building winning companies.
