2. Idea Validation on Reddit
Search for Pain Points
Before building, search Reddit for people complaining about the problem you're solving. If no one's complaining, there might not be a problem.
Post "Would You Use This?"
Share your concept in relevant subreddits and ask for feedback. Be prepared for brutally honest responses—that's valuable.
Find Existing Solutions
Search for competitors. If people recommend alternatives, study what they like/dislike about them.

5. Growth Hacking Tactics
Monitor Problem Keywords
Track keywords related to the problem you solve. When someone posts about that problem, be there with your solution.
Engage in Niche Subreddits
Don't just target startup subreddits. Find where your actual users hang out and become a valuable member.
