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.

Community Platform

Monitor Any Subreddit for Buying Signals with a Custom RSS Station

SignalPipe pre-monitors 100+ subreddits, but you can add any subreddit as a custom RSS station. Niche subreddits are often the highest-signal sources for specialized B2B markets.

What is Reddit (RSS)?

Every public subreddit on Reddit has a built-in RSS feed accessible at reddit.com/r/{subreddit}/.rss. SignalPipe pre-configures monitoring for 100+ high-signal B2B subreddits, but any public subreddit can be added as a custom station for monitoring your specific niche.

Why monitor Reddit (RSS) for buying signals?

The most valuable subreddits for niche B2B markets are often communities with fewer than 50K members where everyone is deeply invested in the topic. These high-relevance, low-noise subreddits can be the best signal sources for specialized products that wouldn't surface on general boards.

How to monitor Reddit (RSS) with SignalPipe

Find the subreddit for your niche

Search for communities where your buyers discuss their work. Niche subreddits (r/devops, r/microsaas, r/B2Bsales) often have better signal than large general ones.

Add the subreddit RSS as a custom station

Use the format reddit.com/r/{subreddit}/.rss as the station URL in SignalPipe. No Reddit API key needed — the RSS feed is fully public.

Combine with existing pre-configured stations

Your custom subreddit station runs alongside SignalPipe's pre-configured subreddit monitors. Intent scoring uses the same 4-stage pipeline for all stations.

Test anchor sentences against niche vocabulary

Niche subreddits use specialized terminology. Anchor sentences should include the specific language your buyers use in that community.

Example Reddit (RSS) buying signals

"Anyone here using an AI agent for sales prospecting? Curious what the workflow actually looks like"

Why it's a signal: Market research from a practitioner — directly relevant to SignalPipe's value proposition.

"r/microsaas: What do you do for lead gen when you have no time and no budget for ads?"

Why it's a signal: Explicit constraint statement — price-sensitive founder actively looking for a solution.

"We just set up automated monitoring for our community mentions — happy to share our stack"

Why it's a signal: Validation post — potential user sharing similar workflow creates discussion and peer signals.

Add these when calling signalpipe_add_product. SignalPipe uses them to detect semantically similar posts across your Reddit (RSS) station.

1"looking for a tool to monitor subreddits for mentions of our product category"

2"need an RSS-based approach to track buying intent across reddit communities"

3"want to add custom subreddit monitoring to our sales prospecting workflow"

4"automating reddit monitoring for warm leads without reddit API rate limits"

Frequently asked questions

Does SignalPipe require a Reddit API key for monitoring?

No. SignalPipe uses the public RSS/JSON feeds that Reddit provides for every public subreddit. No Reddit API account, OAuth, or developer app is needed. This also means no rate limits from Reddit's API tier changes.

How is custom RSS monitoring different from the pre-configured subreddit pages?

Pre-configured subreddit stations (/monitor/reddit/*) are set up for you out of the box. Custom RSS stations let you add any subreddit not in the pre-configured list, including NSFW communities (you must configure this yourself), private-to-logged-in subreddits (not supported), and hyper-niche communities.

Can I add multiple subreddits as separate stations?

Yes. Each subreddit RSS URL is a separate station. You can monitor as many as your plan allows — the Starter plan includes 10 stations, Pro includes unlimited.
