A signal is a real-world event that makes someone worth reaching out to right now — not next month, not last week, now.

​
Why signals matter

Cold outreach converts poorly because you’re guessing at timing. Signal-based outreach converts several times better because you’re reaching out because something changed — and that “because” ends up in your first message. Example without a signal:
Hi Sarah, wanted to introduce myself…
Example with a signal:
Sarah — saw your Series A announcement last week. Congrats. Founders at that stage usually run into X — happy to share how Y other companies handled it.
Same person, same product, dramatically different reply rates.

The 8 signals Guhan supports today

Guhan groups signals into three categories in the WHEN panel:

​
Content & Engagement

People who authored or engaged with LinkedIn posts matching your keywords. You pick target = authors (people writing about the topic — pain language, recommendation requests), engagers (people liking/commenting on those posts — launch announcements, vendor showcases), or both.
Paste specific LinkedIn post URLs. Every day, Guhan picks up new reactors and commenters on those exact posts. Posts decay over time — new engagement pulled 2×/day the first week, 1×/day weeks 2-3, then dormant.
People who reacted to or commented on posts by your competitors. Paste a LinkedIn company URL (watches every employee’s posts) OR an individual profile URL (e.g. their CEO).

​
Career Changes

Paste LinkedIn company URLs. Guhan surfaces people who joined those companies as executives or directors in the last 90 days — a common buying-trigger window.
Same shape as “New executive” but narrower — only senior leadership (C-level, VPs). Higher-stakes hires; longer decision-making windows.

​
Hiring & Growth

Companies that announced a funding round recently. Pick which stages count (seed, Series A, B, etc.) + the recency window.
Companies whose headcount grew above a threshold (e.g., +30% in 6 months). Growth = budget = active buying window.
Companies posting jobs in specific departments (Sales, Engineering, Marketing, etc.) with a minimum open-jobs count. Great for tools that scale with team size.

​
Coming soon

Wired into the registry but not yet shipped as a customer-usable signal. It’ll surface companies detected as using a specific tool (via public tech-stack signals). Reach out to hello@guhan.ai if you’d find this useful — we prioritize by demand.

​
How you configure signals

When you create or edit a Watchlist Agent, the WHEN panel shows all 8 signals grouped as above. Click any signal to open its configuration:
  • Recently raised funding — pick stages (seed, Series A, B, C+) + recency (30 / 60 / 90 / 180 / 365 days)
  • Hiring in specific areas — pick departments + minimum open-jobs count
  • Engaged with competitors’ content — paste 1-3 LinkedIn company URLs (your competitors)
  • Engaged with specific posts — paste exact LinkedIn post URLs
  • Posted about specific topics — enter keywords/phrases + pick target (authors / engagers / both)
  • New executive / New leadership — paste LinkedIn company URLs to watch

​
Cost

Signal-driven searches use different LinkedIn / Crustdata / HarvestAPI data sources. You pay per landed prospect (1 credit), not per signal-hit. See Plans and credits for the full breakdown.
Signals dramatically improve reply rates but they also narrow the funnel. If your Watchlist Agent is finding too few prospects, loosen a signal or remove it. If it’s finding too many low-quality prospects, add a stricter signal or tighten your ICP.
You can skip signals entirely — Guhan will just find people matching your ICP (job title + location + industry + company size). This is the highest-volume mode; reply rates are lower.
