Jeff Schumacher is one of the coolest execs it has been my privilege to interview here in Davos. The CEO of 500-person multinational BCG Digital Ventures lives in California, and is one of the most recognisable venture capital investors. To shake up the energy, we went for my first ever “walking interview” around the Davos Congress Centre – and the result was fascinating. Have a read/listen. Especially if you have an idea for a killer business. – Alec Hogg
