Hello.

My name is Hsu Ken Ooi. I'm Co-Founder and Managing Partner at Iterative, a startup accelerator focused exclusively on Southeast Asia.

Before Iterative, I started 2 companies Weave (YCS14, acquired by LunchClub) and Decide (acquired by eBay). I studied mathematics in school, played video games for money and I'm originally from Penang, Malaysia.

I typically write about startups but will occasionally write about other things. You should subscribe.
