My theory so far is that the initial spike during launch is what gives the product the momentum. That is why I asked my question specifically around the launch. Here is what I have tried so far after the launch with one of my products that has been sold for the code-base. - Pre-launch page to collect emails (collected about 400, when emailed only about a dozen people signed up) - Tried Google adwords with only 0.0005% conversion rate (which ended up being prohibitively expensive for my budget). - Posted on HN :) - Emailed about a dozen sites that could potentially have an article about my product. - Contracted a 3rd party company to make cold calls. - Sent out printed flyers to potential customers. - Personally visited some potential customers and pitched the idea. - PR web sites where I published a couple of press releases. Above activities resulted in about a dozen free tier users. Are there any other avenues that you used to bring more traffic to your product after the launch?
