Since the launch of Bullish Premium, I've been doing many things to spread the word out.
I set up a new website, started engaging more actively on Twitter, promoted it on LinkedIn, launched on Product Hunt, wrote a detailed article about the process, and posted on Hacker News along with some subreddits and newsletter directories.
It wasn't a home run by any means, but we've managed to add around 450 new subscribers since the past month and a few more paid subscribers to a total of 14, which brings Bullish to a monthly recurring revenue of about $75.
