Hacker News Is Full of Buyers. Are You Watching?

"Ask HN: What tools do you use for X?" — SignalPipe catches these the moment they're posted.

Hacker News has an unusually high density of technical founders, early adopters, and B2B software buyers. Ask HN threads, Show HN posts, and comment chains regularly surface people with real buying intent who respond well to genuine, expert replies.

SignalPipe monitors HN via the hnrss.org API — configurable by keyword, so you can track any combination of topics relevant to your product. Posts and comments are scored using the same two-pipeline process as Reddit: a 3-stage scoring filter (keywords, semantic scoring, sarcasm detection) followed by a 3-judge AI drafting swarm.

Because HN replies from knowledgeable people get upvotes and visibility, a single well-placed reply can generate traffic beyond the original poster.

How it works

1

Keyword-scoped feeds

Track any combination of keywords across new HN posts, using feeds like hnrss.org/newest?q=YOUR+KEYWORDS.

2

Ask HN and Show HN coverage

Both question posts and product launches are monitored — catching both direct buyers and people evaluating competitors.

3

High signal-to-noise

HN's quality bar naturally filters low-effort posts, so your feed is already cleaner than Reddit. SignalPipe's scoring layer removes the remaining noise.

4

Reply, don't just watch

SignalPipe drafts a reply to every qualifying post. You spend 30 seconds reviewing instead of 30 minutes writing.
