Agreed. You need to leave. Now.
Sell your stuff, get currency, use your international connections. It's going to be the hardest thing you've ever done, but liberty is the most important. Who knows what will happen in prison and for how long they will detain you.
Also, depending on how technically competent your government is, you need to get all your services offshore now: Wuala for storage (like dropbox - based in Switzerland); Runbox for email (based in Norway); servers in somewhere like Europe or other nearby friendly countries that provide sufficient bandwidth... Burner phone, TOR, careful about your online presence, etc. In the meantime, move locally and rent a place cash under the table where address won't be registered. Basically, become invisible to your government.
Then you want to move your business domicile and bank accounts elsewhere if feasible so your local government can't confiscate your business once you do leave. Read into the 5-flag theory: http://en.wikipedia.org/wiki/Perpetual_traveler
You're entrepreneurial, intellectually curious, freedom-loving - rotting away in prison would be a waste of great talent and not to mention a human rights violation. Starting a startup is hard enough as it is, it's important. But not as important as liberty. If you plan correctly, you can have both. Obviously, I (or likely none of us on here) cant fully empathize with your situation - best of luck!!
Edit: Are you in Singapore? I know Singapore is socially strict, but I thought it was secular. If you're in Malaysia, it's a different story. Moving your domicile and bank accounts to Singapore might make a lot of sense if you're in Malaysia.
