Buying Signal Detector
Know which accounts just entered a buying window. Before your competitors do.
Daily AI-scored buying signal digest from funding, leadership, and growth signals. Monitors NewsAPI and RSS feeds across your target accounts. Delivers ranked Slack briefing every weekday morning. We designed this after an AE missed a buying signal buried on page 3 of an email thread — the prospect had asked about implementation timelines, a strong intent indicator. The detector scans communications for signals humans overlook.

B2B sales teams spend 65% of their time on non-selling activities, with manual lead qualification consuming the largest share. As contact databases grow past 10K records and buying committees expand to 6-10 stakeholders, human-only qualification cannot keep pace. Automated scoring with transparent, auditable criteria lets reps focus on conversations instead of spreadsheets.
One Analyst. Daily Signal Sweep. Ranked Slack Digest.
Step 1 — Signal Fetcher
Code Only
Every weekday at 07:00, the scheduler triggers three parallel NewsAPI queries — funding rounds, leadership changes, and growth signals (hiring surges, expansion announcements). Articles from the last 24 hours are collected, deduplicated against a 7-day URL cache, and assembled into a unified signal set. Zero LLM cost.
Step 2 — The Analyst
Tier 1 Reasoning
What does The Analyst actually decide? the primary reasoning model evaluates each signal against your configured ICP profile — industry match, company size, geography, persona keywords. Assigns ICP relevance scores and classifies signal strength as WEAK, MODERATE, or STRONG. Scores the overall day heat: HOT (high-relevance signals detected), WARM (moderate signals), or COLD (nothing actionable). Chain-of-thought enforced.
Step 3 — The Formatter
Code Only
This step exists because raw data alone is not enough. Converts the ranked signals into a Slack Block Kit digest. HOT signals surface first with company name, signal type, strength badge, and ICP score. Day heat badge appears at the top. COLD days produce a minimal empty digest — zero noise. Zero LLM cost.
Step 4 — Slack Delivery
HTTP
Without this step, upstream analysis sits idle. Posts the formatted digest to your configured Slack sales channel via Bot Token. One message per day. Non-blocking — if Slack fails, the workflow still completes and returns the digest in the webhook response.We tried three providers for $0.016 savings per lead. Three API keys, three billing accounts — the customer friction was not worth it.
That's the full pipeline. Here's what it intentionally does NOT do — and why those boundaries exist.
What It Does NOT Do
Does not monitor social media, job boards, or proprietary databases — NewsAPI and configurable RSS feeds only
Does not integrate with CRMs — delivers a Slack digest, not CRM record updates
Does not provide historical trend analysis — each run is a point-in-time 24-hour sweep
Does not persist deduplication across workflow restarts — static data resets on reactivation
With those boundaries clear, here's everything that ships when you purchase.

Frequently Asked Questions
How does it differ from Job Change Intent Scorer?+
Distinct products with zero overlap. JCIS monitors individual contact job changes for SDR re-engagement via web search and updates Pipedrive. BSD monitors company-level buying signals (funding, leadership, growth) from news sources for AE account prioritization and delivers a daily Slack digest.
What signal types does it detect?+
Three categories: (1) Funding — Series A/B/C rounds, acquisitions, IPO filings. (2) Leadership — new CTO/VP hires, executive departures, board appointments. (3) Growth — hiring surges, office expansions, product launches, partnership announcements.
How does ICP scoring work?+
You configure your ICP profile in the Config Loader node: target industries, company size range, geographies, persona keywords, excluded companies, and signal boost keywords. The Analyst evaluates each signal against this profile and assigns a relevance score. Signals matching multiple ICP criteria score higher.
How much does each run cost?+
ITP-measured: $0.093/run blended average across 20 test fixtures. HOT days with many signals cost slightly more. COLD days with zero signals skip the LLM call entirely — $0.00 cost.
What happens on days with no signals?+
The Empty Check node detects zero signals after deduplication and skips the LLM call. A minimal COLD digest is posted to Slack noting no actionable signals. Cost: $0.00.
Why is there a separate scheduler workflow?+
n8n cannot have both a Schedule Trigger and a respondToWebhook node in the same workflow. The split-workflow pattern separates scheduling (3-node cron workflow) from processing (23-node main workflow). The scheduler calls the main workflow via HTTP Request on the cron schedule.
Does deduplication persist across restarts?+
Deduplication uses n8n workflow static data with a 7-day URL TTL. Static data resets when the workflow is deactivated/reactivated or when n8n restarts. After a restart, you may see previously processed articles re-sent for one run.
Is there a refund policy?+
