Signals monitors real-time technology changes across 50M+ domains. When a company subscribes to, drops, or switches technologies, that change becomes an actionable delivered with verified decision-maker contacts. Your team can act on it right away. Signals dashboard showing five signal types — New Technology Adoption, Technology Churn, Active Buyers in Category, Buyers in Related Categories, and Real-time Backend Signals — each with live activity counts

Signal types

TechnologyChecker tracks six types of signals:
Detect when companies start using a technology, including backend tools and standalone platforms that browser-based tools miss.
  • Real-time adoption detection across 50M+ domains
  • Timestamp of first detection
  • Signal confidence scoring
  • Trend analysis: is this technology gaining or losing market share?
Example: “Alert me when prospects adopt Stripe” — identifies companies investing in payment infrastructure.Use case: Sell complementary products to companies actively building their stack.
Detect when companies stop using a technology. Identify frustration signals and displacement opportunities before competitors notice.
  • Real-time removal detection
  • Estimated removal date
  • Churn pattern analysis using historical data
  • Early warning indicators before full removal
Example: “Alert me when companies drop Intercom.” Identifies companies actively seeking alternatives during the 30-60 day evaluation window.Use case: Reach out with your alternative while the prospect is evaluating options.
See what companies switched to after dropping a technology. Competitive displacement, in real time.
  • Automatic detection of replacement technology
  • Migration pattern matching against historical data
  • Competitive positioning insights
Example: “Alert me when companies switch from Intercom to Zendesk.” You’ll see competitive movements as they happen.Use case: Intervene during active technology evaluations or target companies switching to a tool you integrate with.
Track when prospects adopt your competitors’ tools and intervene during the evaluation window.Example: “Alert me when target accounts adopt Marketo.” Engage before they fully commit.Use case: Competitive selling with technology context and verified contacts for decision-makers.
Monitor your existing customers for signs they’re evaluating competitors. Proactive retention outreach based on real signals.Example: “Alert me when my customers add BambooHR.” Catch at-risk accounts before renewal.Use case: Customer success teams can address migration concerns before renewal conversations.
Detect when companies adopt backend tools (n8n, databases) and standalone platforms (Airtable, Notion) that signal operational changes.Example: “Prospect adopted n8n + Airtable.” They’re building custom workflows. Strong buying signal.Use case: Identify companies building operations infrastructure who need your platform.

Signal confidence scoring

Every signal includes a confidence score so you can prioritize high-certainty detections:
Signal sourceConfidence levelDescription
DNS-based detectionHigh (95%+)CNAME, NS, MX record changes
SSL certificate-basedHigh (95%+)Certificate transparency log changes
HTTP header-basedHigh (85%+)Server headers, response signatures
Code-based detectionMedium (70-85%)JavaScript, HTML pattern changes
Infrastructure inferenceMedium (60-80%)IP, ASN, CDN fingerprint changes
When building automated workflows, filter on confidence score to focus on the highest-certainty signals. Scores above 80 indicate detection backed by multiple independent signal sources.
