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.

Startup Ecosystem

What is Y Combinator News?

Y Combinator companies represent some of the highest-velocity software buyers in the market — funded, growth-focused, and actively evaluating tools to scale. YC News (which feeds Hacker News) aggregates the latest updates, and the broader YC ecosystem generates constant signal through job postings, launches, and founder discussions.

Why monitor Y Combinator News for buying signals?

YC founders buy fast. A post from a YC founder asking "what do you use for [category]?" often converts to a paying customer within days if you reach them first. The YC ecosystem also has strong word-of-mouth — one founder's recommendation spreads to the whole batch.

How to monitor Y Combinator News with SignalPipe

Monitor HN and YC-specific feeds

The primary YC signal source is Hacker News. Use hnrss.org keyword feeds for your product category, specifically targeting "Ask HN" posts.

Track YC Startup Directory launches

New YC companies launch constantly. Add feeds for startup directory announcements — these teams are actively buying tools in their first weeks.

Monitor batch announcement posts

Each YC batch generates a wave of HN posts from new founders discussing their stack choices. These appear in predictable patterns every March and September.

Reach out with founder context

YC founders are identifiable — many have public profiles. Your agent crafts outreach that acknowledges the YC context and speaks to growth-stage buying priorities.

Example Y Combinator News buying signals

"Ask HN: What do YC founders use for outbound sales when you're pre-PMF?"

Why it's a signal: Direct pre-purchase research from a YC founder — highest possible intent.

"Just got into YC — building our sales process from scratch. What's the move for finding early customers?"

Why it's a signal: First purchase decision — this founder has budget and urgency.

"We just raised seed. Finally have budget to stop doing everything manually. What tools should we buy first?"

Why it's a signal: Post-funding purchase acceleration — explicit buying intent with budget confirmed.

1"yc founder looking for sales tools for early stage startup"

2"just raised funding and buying tools to scale our sales process"

3"pre-pmf founder trying to find first customers without a sales team"

4"what sales stack do ycombinator startups use at seed stage"

Frequently asked questions

Is there a dedicated YC RSS feed?

YC publishes news through Hacker News, which has a public RSS feed. For batch launches, there's no single aggregated RSS — the best coverage comes from monitoring HN for YC-related keywords and "Ask HN" posts.

Are YC founders a realistic market for a bootstrapped product?

Yes. YC companies buy tools at all price points. Early-stage YC founders often prefer lightweight, founder-built tools over enterprise software — SignalPipe's positioning fits this segment well.

How do I specifically target YC companies vs the broader HN audience?

Use anchor sentences with YC-specific language ("ycombinator", "batch", "pre-PMF", "post-seed") to improve the embedding similarity score for YC-context posts. The LLM scoring layer also considers company stage signals.
