I'm in Manila and running my startup here. Email me.
Yep, the SEA startup scene is in full throttle in the past few months. The recent buyout of Koprol by Yahoo, Octazen by Facebook is definitely a sign.
IMO, you can't go wrong with Manila :)
I'm interested in the Philippines. Is there a startup culture in Manila or Cebu, and what does that look like?
The startup scene in the Philippines is concentrated on Manila. Friendster, Insync, ProudCloud seems to lead the pack. I suggest you mail @terpua since he can introduce to the details.
