Where to share pre-launch MVP?

@Barin try out: Ship by Product Hunt and Betalist. What is the product about ?

Here's a list of communities/channels I post to generally that are high quality for the most part and where our early users came from. Most of these aren't just places to post a link to your product, but you can share content there/be part of the conversation and grow your audience.

I've found Twitter to work really well if your audience is other dev, design, or startup people. My first 100 beta signups were from a single screenshot of my product that I shared to Twitter. You need to have an existing following of course, but it doesn't need to be massive. A couple hundred followers in your niche can work if people are into what you're building and retweeting your posts.
