TrendScan — Find customers on Reddit - AI-powered Reddit monitoring for sales leads

I built TrendScan as a solo founder in Vietnam after struggling to find customers on Reddit manually. I'd spend hours scrolling through subreddits, trying to spot people asking for exactly what I built. TrendScan solves this — it watches keywords, scores posts by buying intent using AI, and sends alerts to Slack/Discord/Email. It's helped me and early users convert Reddit browsers into paying customers. I learned a ton building this: websockets at scale, CQRS patterns, and that Vietnamese coffee keeps you coding at 2AM ☕ Would love your feedback!
