SignalPipe is an agentic sales pipeline that monitors Reddit, Hacker News, and RSS feeds 24/7 for buying-intent signals. It uses AI to score each signal, draft a reply, and surface only real leads for human review and approval before anything is sent.

How does SignalPipe detect buying intent?

SignalPipe uses a three-stage pipeline: a keyword gate for cheap pre-filtering, OpenAI text-embedding-3-small for semantic similarity scoring against your anchor sentences, and a three-model LLM swarm (Optimist, Analyst, Skeptic) that evaluates each post independently. A hard skeptic veto suppresses any signal the most skeptical judge dismisses.

Does SignalPipe send messages automatically?

No. Every message requires human approval before it is sent. SignalPipe drafts the reply and queues it for your review — you approve, edit, or reject each one. Nothing is sent without your explicit sign-off.

What platforms does SignalPipe monitor?

SignalPipe monitors Reddit (via subreddit RSS feeds), Hacker News (via hnrss.org keyword feeds), and any RSS-compatible feed. You can add as many sources as you want per product.

How is SignalPipe different from Clay or Apollo?

Clay enriches contact lists you already have. Apollo is a cold email database. SignalPipe generates net-new leads by detecting live buying signals — finding people who are actively posting that they need what you sell, right now, in public communities.

SignalPipe has four tiers: BYOK ($19/mo — bring your own LLM key, 3 products, 50 leads/day, 1,000 prospects), Starter ($49/mo — 2 products, 25 leads/day, 500 prospects), Growth ($149/mo — 10 products, 250 leads/day, 5,000 prospects), and Scale ($499/mo — unlimited everything). Open Source is free for self-hosters. The first 100 waitlist members get 50% off for 3 months.

Does SignalPipe work with NVIDIA NeMoClaw?

Yes — fully compatible out of the box. NeMoClaw is NVIDIA's enterprise distribution of OpenClaw, so any OpenClaw plugin installs and runs on NeMoClaw without modification. For on-prem deployments, SignalPipe also supports local model inference: set COMPANION_LLM_PROVIDER=openai_compatible and point it at a locally running Nemotron or any OpenAI-compatible endpoint. Your leads, prospect data, and generated messages never leave your infrastructure.

Can I run SignalPipe fully on-premises?

Yes. Self-host the FastAPI backend on your own server, connect it to your own PostgreSQL database, and configure the companion message generation to use a local model via any OpenAI-compatible endpoint (Nemotron via NeMoClaw, Ollama, LM Studio, vLLM). The only external call that remains is the OpenAI embedding API for signal scoring — and that can be swapped for a local embedding model by request.

What is OpenClaw Hacker News Monitoring?

Hacker News is a goldmine for B2B leads targeting technical buyers. "Ask HN" threads generate hundreds of replies from decision-makers in active evaluation mode. SignalPipe monitors HN keyword feeds via hnrss.org and scores them with the same 4-stage pipeline used for Reddit.

How SignalPipe adds Hacker News Monitoring to OpenClaw

Add HN keyword stations to SignalPipe by calling `signalpipe_add_station` with `platform: "hn"` and an hnrss.org keyword URL. SignalPipe monitors that feed every 10 minutes and surfaces posts where HN members are asking for tools, comparing options, or describing the exact problem your product solves.

How to set up Hacker News Monitoring in OpenClaw

Identify your HN keywords

Choose the keywords your buyers use when posting on HN. "sales automation", "lead generation", "cold email alternative", "intent data" are strong starting points.

Add HN stations

Call `signalpipe_add_station` with `rss_url: "https://hnrss.org/newest?q=your+keyword"` and `platform: "hn"`. Add one station per keyword.

Configure anchor sentences

HN buyers are more technical and specific. Write anchor sentences that reflect their vocabulary — they describe infrastructure, APIs, and integration depth, not "easy to use".

Respond to Ask HN threads

Ask HN threads are especially high-value — a single thread can have hundreds of readers in your ICP. SignalPipe surfaces these and drafts replies that add genuine technical value.

Frequently asked questions

Why is Hacker News valuable for B2B lead generation?

HN attracts technical founders, CTOs, and operators who make purchasing decisions. Ask HN threads about tools are explicit buying signals. A single thread can reach thousands of readers in your ICP and last for days in search results.

How does HN RSS monitoring work?

hnrss.org provides real-time RSS feeds for HN by keyword. SignalPipe polls these feeds every 10 minutes and runs new posts through the intent scoring pipeline.

Can I monitor specific HN users or domains?

Not natively — SignalPipe monitors keyword-based feeds. For user-level or domain-level monitoring, you would need a custom RSS setup from hnrss.org.

How do I respond to HN posts without getting flagged?

HN is hostile to promotional replies. SignalPipe's drafts are written to be genuinely helpful first. You should always add real value in your reply — mention SignalPipe only if directly relevant, never as the opening line.
