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.

OpenClaw Plugin

How to Install SignalPipe on OpenClaw

One command. 11 tools. First scan in under 5 minutes. Here's exactly how to install and configure SignalPipe in your OpenClaw gateway.

Install SignalPipe on OpenClaw

openclaw plugins install signalpipe

Available on ClawHub · MIT licensed · Open source on GitHub

What is OpenClaw Plugin Installation?

SignalPipe installs as a standard OpenClaw plugin through the ClawHub registry. After installation, all 11 SignalPipe tools are immediately available in your OpenClaw agent session — no API key configuration required to start.

How SignalPipe adds Plugin Installation to OpenClaw

The install process is designed to be frictionless: one command to install, one tool call to add a product, one tool call to add a station, one tool call to run your first scan. Most users see their first scored lead within an hour of installation.

How to set up Plugin Installation in OpenClaw

Run the install command

In your OpenClaw gateway, run: `openclaw plugins install signalpipe`. This downloads and registers the plugin from ClawHub.

Verify the tools

Ask your OpenClaw agent to list available SignalPipe tools. You should see all 11: signalpipe_add_product, signalpipe_add_station, signalpipe_scout_now, signalpipe_get_missions, and 7 more.

Add your first product

Call `signalpipe_add_product` with your product name, a brief description, and 5-10 anchor sentences. This takes under 2 minutes.

Add a station and scan

Call `signalpipe_add_station` with a subreddit or HN feed URL. Then call `signalpipe_scout_now` to trigger your first scan. Check results with `signalpipe_get_missions`.

Frequently asked questions

Is SignalPipe available on ClawHub?

Yes. SignalPipe is listed in ClawHub and installs via `openclaw plugins install signalpipe`. It is a verified plugin — the source code is public on GitHub for audit before installing.

Do I need an API key to install SignalPipe?

No API key is needed for the plugin itself. The backend scoring engine connects automatically on first scan. For the BYOK tier ($19/mo), you provide your own LLM key — this is configured via `signalpipe_configure_llm`.

What OpenClaw version does SignalPipe require?

SignalPipe requires OpenClaw 2026.3.x or later (the version that introduced ClawHub and the plugin API). Check `openclaw --version` to confirm.

Can I self-host the SignalPipe backend?

The plugin interface is MIT licensed and can be self-hosted. The scoring engine (RL weights, LLM swarm configuration) is closed source. Self-hosting the open-source plugin connects to the hosted scoring API by default.
