I would suggest a few things before going live.
Create a pre-launch page. (Use LaunchRock) Build your list from ground up. (Start blogging) Integrate a referral program like Trevolta did. Make them share your voice via social media to get ahead in the list of invitees for the product launch. Create a pre-launch video. List your product on Betalist and other similar websites to get beta testers. List your product on ProductHunt, Hackernews, Reddit etc. Create a press kit so journalists can find about who your are and what you do to create a story.
