There definitely are development in technology area. There are now more "start ups" than 3 years ago. But the thing is the infrastructure is pretty much broken still.
The Internet is (still) slow and expensive. (A year ago, I spent the whole morning by trying to 'bundle install' and then the other half of day, the electricity is gone). So, basically, small companies are struggling to roll out their own products and from months to months, they have to make their cashflow by doing services/outsource.
Also there are foreign tech companies (eg Rocket Internet) who are trying to clone their existing stuffs into the Myanmar and trying to make it work. I can say they are struggling either because our culture is different. What works in Singapore/Vietnam might not work in Myanmar.
Recently, a friend of mine company tried to get some seed funding from outside for his startup and he had to set up a lot of extra work such as opening the same name company in Singapore, get the money for the Singapore company and then bring it back with him to Myanmar. Because there are still lots of restrictions around there. Feel free to ask me anything and I could try my best to answer them.
