# Signals

> The triggers that tell Guhan when to reach out to someone.

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

<AccordionGroup>
  <Accordion title="Posted about specific topics">
    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`.
  </Accordion>

  <Accordion title="Engaged with specific posts">
    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.
  </Accordion>

  <Accordion title="Engaged with competitors' content">
    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).
  </Accordion>
</AccordionGroup>

### Career Changes

<AccordionGroup>
  <Accordion title="New executive (in last 90 days)">
    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.
  </Accordion>

  <Accordion title="New leadership (C-level / VP)">
    Same shape as "New executive" but narrower — only senior leadership (C-level, VPs). Higher-stakes hires; longer decision-making windows.
  </Accordion>
</AccordionGroup>

### Hiring & Growth

<AccordionGroup>
  <Accordion title="Recently raised funding">
    Companies that announced a funding round recently. Pick which stages count (seed, Series A, B, etc.) + the recency window.
  </Accordion>

  <Accordion title="Hiring growth">
    Companies whose headcount grew above a threshold (e.g., +30% in 6 months). Growth = budget = active buying window.
  </Accordion>

  <Accordion title="Hiring in specific areas">
    Companies posting jobs in specific departments (Sales, Engineering, Marketing, etc.) with a minimum open-jobs count. Great for tools that scale with team size.
  </Accordion>
</AccordionGroup>

### Coming soon

<Accordion title="Uses a specific technology">
  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](mailto:hello@guhan.ai) if you'd find this useful — we prioritize by demand.
</Accordion>

## 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](/workspace-settings/plans-and-credits) for the full breakdown.

<Note>
  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.
</Note>

## No signals = pure ICP search

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.
