Here's a list of places to post your product:
<a href="https://github.com/mmccaff/PlacesToPostYourStartup" rel="nofollow">https://github.com/mmccaff/PlacesToPostYourStartup</a><p>Meetups work well too, especially for B2B and niche products, since a lot of people going to meetups are going for the same reason you are; to show off their thing.<p>Disclaimer: I'm starting on this journey myself and these are the things I've found limited success with thus far.
It probably depends on the type of product.<p>Few Options:
1. Friends, Family, Colleagues etc. Although, I do not prefer this option, as friends and known colleagues tend to be sugar coat their feedback, and that is not something you want.<p>2. One of them right here: <a href="https://news.ycombinator.com/show" rel="nofollow">https://news.ycombinator.com/show</a><p>3. If you can showcase your product on KickStarter or other crowd funding - brilliant, as it also kind of proves people will be willing to pay for your product in future.<p>4. Meetup Groups etc, walk into these groups, if you find people who would fall into your target profile. Do not hesitate to politely ask, if they would like to have a look.<p>5. If you have a target list, offer them free access, with a concise email or some other medium.<p>tl;dr: Anywhere you can see right people, offer.
