I use this database to connect with subject matter experts on Reddit so that I can ask questions to professionals in different fields, such as marketing or SaaS development to improve my skills if I need help on something.
A lot of people don't know who to connect with for better advice on a specific topic, so to solve this problem, I scraped and analyzed posts, comments, user profiles, karma and user consistency/activity for different Reddit users to find the most experienced users in a specific subreddit. There are around 50 users of the highest contributors/relevancy for each subreddit.
After that, I put all of the user profiles in a database, and added some advanced filter options so that you can find users based on subreddit or specific keywords/niches.
For example, this is also how I got my first SaaS application from 0 to 72 sales, as I found it easier to get help from people who have experience in SaaS, and I connected with them to ask how I can improve my landing page, or my marketing skills etc.
If you are wanting to find and connect with relevant users, this database will save you tons of time!
