I would love to chat on concrete strategies that could work.
I've done this on a small scale for my product, but it worked nicely, and I learned some useful techniques. I'd be happy to talk with you about the process, and also answer any other startup questions you might have.
Best of luck,
I'm a "Reddit Marketer". I built a business and acquired all my initial customers from Reddit and Facebook Groups, without spending a dime on marketing.
We hit 6 figures in revenue our first year.
I wrote about this, and ultimately my post became the #35 Top Post of 2015 in r/Entrepreneur, a community of nearly 200,000 members (and drove even more clients to us): https://www.reddit.com/r/Entrepreneur/comments/3s5e7m/0_to_6_figures_in_1_year_lessons_learned/
I also wrote an article called "How to Market on Reddit (Without Getting Eaten Alive)": http://launchyourrevolution.com/market-reddit-without-getting-eaten-alive/
I've gotten several posts to the front page of Reddit (the #9 most popular site on the internet), including this one I did for The Askhole Podcast: https://www.reddit.com/r/funny/comments/40zrh9/give_a_man_a_fish/
I can provide verification that this was actually me, and screenshots of the post reaching the #10 spot on the front page of Reddit.
I am extremely comfortable marketing on Reddit, so let me know what type of business/service you're wanting to promote, and I can give you some advice on giving it the best chance of success.
I've been using Reddit to build a community for a couple of small local brands in my area!
I really enjoy Reddit because of the ability to create organic traffic from the site. Once you create a post, you can see if anyone reacts to it organically, or is familiar with your product or service.
It's also a great platform to interact with your consumers. You can answer any questions they might have, or provide them with information they are seeking about the product.
I've taken a more informational approach to Reddit starting out because a lot of people weren't familiar with the brands in the area. I always ask if anyone has questions, and I've been pretty successful in communicating with what used to be 1 or 2 consumers every couple of weeks to at least 5 a week.
The more time and effort you put into it, the better results you'll get.
I recommend it!
