An interview with retail giant METRO CEO Olaf Koch on corporate innovation and accelerating startups

We recently had the opportunity to catch up with Olaf Koch, the chairman and CEO of METRO Group, a Düsseldorf, Germany-based holding that's in the business of wholesale, food retail and non-food speciality stores spread across 25 countries.

With more than 220,000 employees working for brands like Makro, Saturn, Media Markt and METRO, the company has emerged as one of Europe's corporations most keen to engage with the tech startup community to help create a healthy 'digital ecosystem for the catering and hospitality industry', as they call it.
