First of all: not looking for a co-founder, but if you'd like good company - read on.
I'm working on my own stuff now (quit my job) and I figured going to Thailand to live for 6 months would actually save me some money. I already lived there for 6 months and it was great. I had a studio in a modern building with a gym and a pool on the roof with a beautiful seaview, which was perfect because I didn't have to actually waste my time to get to the gym. And it all costed me around $400/mo. In my opinion Thailand may be the ultimate location for a startup's stealth mode, allowing to fully concentrate and relax when needed.
What I'm looking for is good company, a technical person who's bootstrapping a startup and with whom for that reason I potentially have a lot in common. I think it's important to have at least one person to talk to about startup and technical problems. We could rent two rooms in the same or nearby buildings and... well... work! Occasional beers and discussions as well as island trips are also on the list. Like I said, I lived there for 6 months, so I know the place.
My contacts and bio are in my info. Please ask me anything here, be happy to answer.
For good company during travelling, try couchsurfing. It's big everywhere in Asia.
