SignalStac is an AI agent that watches Reddit, Hacker News, and forums for conversations where your product is already relevant. It ranks the best threads, explains why they matter, and gives you the context to respond without manually scanning feeds all day.

Hey Product Hunt 👋
I built SignalStac while preparing to launch wacht.dev.
I kept manually scanning Reddit, Hacker News, and forums for people already talking about problems Wacht could help with: auth, agents, webhooks, and infrastructure for AI-native apps.
That process was slow, repetitive, and easy to miss.
So I built SignalStac: an AI agent that watches the web for high-intent conversations, ranks the ones worth replying to, and gives you the context you need before jumping in.
It’s not a social scheduler or a generic monitoring dashboard. It’s for founders who want to find conversations where their product is genuinely relevant.
Would love your feedback.

been building in public for about 8 months and the single biggest time sink is manually scanning reddit and HN every morning hoping to catch a thread where my product is relevant. usually miss them by hours when the convo is already cold. this solves an actual daily pain - finding high-intent threads while they're still active is everything. does it surface threads across multiple products/keywords at once, or is it one product per workspace right now?

@galdayan you can define unlimited keywords in one workspace but you can only define one product per workspace so the positioning might get a little ugly if the keywords are entirely unrelated, at least for the agent. If you however plan to sell many products/services under a single umbrella, you can tune the agent accordingly during onboarding and then it will be just fine.
