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.

Reddit Monitoring

Find Startup Buyers on r/startups

r/startups has over 1 million members — early-stage founders and operators actively discussing growth tools, sales tactics, and software decisions.

Station RSS URL

https://www.reddit.com/r/startups/.rss

Paste this when calling signalpipe_add_station with platform: "reddit"

What is r/startups?

r/startups is a community for early-stage founders, startup employees, and aspiring entrepreneurs. Members discuss fundraising, growth, hiring, and — crucially — the tools they use to run and grow their companies. Tool recommendation threads are common and high-quality.

What do buying signals look like on r/startups?

Startup founders on this sub often post when they're scaling past a manual process or changing their toolstack. Look for "we just raised and need to upgrade our tools", "our current setup isn't scaling", or "building our first sales process from scratch". Growth-stage buying intent is common.

Example high-intent posts from r/startups

"Building our first outbound process — what stack are you using?"

Why it's a signal: First-time buyer, stack not decided yet. High openness to new tools.

"Just hit 10 employees and our lead gen is still founder-led. What do I automate first?"

Why it's a signal: Scaling inflection point. Active evaluation of lead gen automation.

"Cold email dying? What's actually working for early-stage B2B outreach in 2026?"

Why it's a signal: Explicit cold email fatigue. Actively looking for alternatives.

Ready-to-use anchor sentences for r/startups

Anchor sentences are buyer phrases written from the buyer's perspective. SignalPipe uses them to score semantic similarity against posts. Add these when calling signalpipe_add_product.

1"startup founder looking for lead generation tools"

2"building first sales process and need tool recommendations"

3"cold email not working, looking for alternatives"

4"scaling past founder-led sales, what tools should I use"
