# Signals API

Lusha Signals are real-time intelligence events that surface meaningful changes happening to your contacts and target accounts. Instead of manually monitoring your CRM for stale data or researching accounts one by one, Signals alert you the moment something relevant happens — a contact changes jobs, a company raises funding, a key hire is made, or a target account shows signs of growth or risk.

## Who Are Signals For?

Signals are most useful for:

- **Sales teams** who want to be notified when a champion changes jobs, gets promoted, or moves to a new company.
- **RevOps and marketing teams** who want to trigger automated workflows based on account-level events — funding rounds, new locations, hiring surges, or tech spend changes.
- **Customer success teams** tracking churn risk signals such as headcount decline, IT spend decrease, or key executive departures.


## How Signals Fit Your Workflow

Signals let you automate your Go-To-Market strategy. Instead of reaching out to a table of accounts at random, you can set triggers to notify your sales team the moment a target account enters a buying window.

For example, a **Surge in Hiring** in a specific department often signals a new budget or project, making it the ideal time to reach out with a relevant solution.

Common use cases:

- **Re-engage past buyers who changed companies** — monitor job change signals for past buyers and trigger personalized outreach when they land at new companies.
- **Time outreach around career milestones** — catch decision-makers during their onboarding period when they're most open to evaluating new solutions.
- **Spot companies in expansion mode** — identify accounts with growing budgets and route high-growth companies to sales before competitors do.
- **Build early warning systems for churn risk** — alert CSMs when decision-makers at customer accounts change jobs, enabling proactive intervention before renewals are at risk.


## How Signals Work

Signals are detected continuously from verified data sources including LinkedIn activity, job posting data, news event monitoring, web traffic data, and IT spend indicators. Each signal represents a discrete, dated event or trend change associated with a specific contact or company.

Signals are updated on the following cadences:

| **Cadence** | **Signal types** |

| Daily | Website visitor tracking |
| Weekly | Hiring surges, job postings, new locations, news events (financial, commercial, corporate, product, people, market intelligence, risk), job change, promotion |

## FAQs

Signals are powered by Lusha's verified, structured data. They're refreshed on the cadences tableed above and validated through multiple sources.
