We want to see solutions in different places; we want to work with those existing ones while opening new chapters, new areas,” he explained. “I think Singapore is a gateway to Southeast Area; it’s a new region. We know the innovation sectors there are huge and technology is booming there. Singapore is a city of nature, so they get it. So it’s really exciting what’s going to happen in Singapore. We take a lot of time and we try to work out where is the next place to go."
