Hey Product Hunt 👋
I’m Arthur, the maker of Shadow Inbox.
I built Shadow Inbox because traditional outbound is exhausting.
Freelancers, agency owners, and SaaS founders waste dozens of hours every week:
• Spamming cold emails with a 1% conversion rate
• Scrolling through Reddit and HN hoping to stumble across a client
• Guessing who actually has budget and intent
• Paying a fortune for Google and Facebook ads
And the worst part? Most of the people you cold-pitch were never looking for a solution in the first place.
So instead of automating spam, I decided to automate social listening.
Shadow Inbox is an always-on AI scout that:
→ Monitors millions of live conversations across Reddit and Hacker News 24/7
→ Tracks real-time complaints and buying signals in your exact niche
→ Uses a custom LLM pipeline to filter out memes, tutorials, and noise
→ Scores every post for genuine buying intent
→ Delivers the hottest, ready-to-buy leads straight to your dashboard
Unlike traditional scraping tools that just dump raw keyword mentions (where tracking "traffic" gets you posts about car crashes), we focus entirely on context. Our AI reads the post, understands the pain point, and guarantees zero noise.
The result:
• You step in as the expert exactly when they need you
• Unfair first-mover advantage over your competitors
• Zero hours spent manually prospecting
I built this out of pure frustration with my own outbound pipeline, and it completely changed how I find clients. Now, I’m opening it up to the PH community.
