# Signal engineering: Know the moment an account needs you.

_https://www.opennous.cloud/features/signal-engineering_

Champion left, expansion requested, competitor mentioned. OpenNous finds these moments in every call, email, Slack thread and product event, with the evidence behind each one and a next step ready.

- **Core signals from day one.** Deal stalled, champion left, expansion requested, competitor mentioned, churn risk, budget discussed, buying signal, objection raised, stakeholder identified, next step missed and next step slipped, plus stage changes, wins and losses from the CRM.
- **Write your own in plain language.** Describe the moment that matters to your business. OpenNous finds it across every account, with the evidence behind each match.
- **Backfill the last 90 days.** A new signal backfills your history right away.
- **Evidence on every signal.** Each signal links to the call, email or product event it came from and says why it matters.

## Signals from every conversation

Calls, emails, Slack threads and product events, matched to the right account, deal and person. The `conversation.call_ended` webhook carries `expansion[]` and `risks[]`, each with its quote.

## A next step, where your team works

Each signal arrives in the Inbox, Slack, the CRM or an AI agent with a drafted next step. A person approves before anything is sent.

## Only the moments worth acting on

- **Your own team never fires a signal.** Replies from teammates and bulk mail are ignored.
- **Old facts expire.** Every fact carries its freshness: fresh, aging, suspect or expired.
- **Every signal says why.** A signal explains why it matters for this account.
- **A person approves every next step.** Nothing is sent or written without approval.

## Where signals land

Slack, HubSpot, Salesforce, Claude (https://www.opennous.cloud/integrations/claude), Grok (https://www.opennous.cloud/integrations/grokbot) and webhooks.

## Frequently asked questions

**What does signal engineering do for a revenue team?**
It turns customer conversations and product activity into clear signals of buying intent and risk, so your team acts on the right accounts before a deal stalls or a customer churns.

**Which signals are included?**
A standard set that works from day one: deal stalled, champion left, expansion requested, competitor mentioned, churn risk, budget discussed, buying signal, objection raised, stakeholder identified, next step missed and next step slipped, plus stage changes, wins and losses from your CRM.

**Can we add signals specific to our business?**
Yes. Describe the moment in plain language. OpenNous applies it to every new conversation and to the last 90 days of history, with the quote behind every match.

**How can we trust a signal?**
Every signal links to the conversation or product event it came from and explains why it was raised, so your team can verify it in seconds.

**How do signals reach the team?**
Through the OpenNous Inbox, Slack, your CRM and your AI agents, or into your own systems through webhooks and the events API.

**Does OpenNous act on signals automatically?**
No. Each signal comes with a recommended next step, and nothing is sent to a customer or written to a system without a person's approval.

**Do we need to set up rules or tag calls?**
No. The standard set works as soon as your tools are connected. You only write a rule when you want a signal of your own, in plain language.

**Where do signals come from?**
From your call recorder or meeting notes (Fireflies, Fathom, Granola), Gmail and Outlook, Slack, your CRM and product usage from PostHog, matched to the right account, deal and person.

**How is a signal different from a CRM alert?**
A CRM alert fires when a field changes. A signal comes from what customers actually said and did, with the quote or event behind it and why it matters for that account.

**Who sees a signal?**
The people who can see the account. A signal from a private email or call shares the business fact, not the message itself, so private conversations stay private.

**Do signals cost extra?**
No. Credits are spent when OpenNous processes a conversation. Signals, insights and account summaries are included.

**Can we build our own workflows on signals?**
Yes. Every signal reaches your systems as a signed webhook, and your agents can read them over the OpenNous MCP server.
