As a founder earlier and now an investor, I have learnt many things about startups but have most importantly learnt to "Unlearn and Think Independently." To ask "What if it hasn't worked out or hasn't been done in the past, can it be different now?"
The chance to build a company only comes along once or maybe twice in our lives. So start something you really want to do. Do it with people you can like. Build it into something enduring and have fun along the way.
I work with founders from 10 different nationalities and this truly represents South East Asia. It is the melting pot of ideas (founders), opportunities (market) and change (products). Come be a part of it.
