It is no mean feat for any entrepreneur to build a company with a $1 Billion+ valuation. Equally, finding these 'unicorns' is no easy challenge itself for any angel investor or venture capitalist.

So how do they (DFJ) do it? How do they spot the entrepreneurs and founders with the greatest potential? How do they nurture them to success? On the 15th of May Heidi Roizen, Operating Partner at DFJ, will share her insights into these questions and many more, in an intimate fireside chat at the Edinburgh University Business School. The event will be in collaboration with Entrepreneurial Scotland and Informatics ventures.
