TheirStack Signal Orchestrator

Find companies by technology stack and hiring signals, score them, and export structured lead intelligence for automations and AI agents.

What it does

This Actor uses your TheirStack API key to search companies and hiring signals, then normalizes, scores, deduplicates, and exports results as structured Apify datasets — ready for CRM enrichment, outbound prospecting, AI agent workflows, and recurring signal monitoring.

This is not a UI scraper. It's an API-backed orchestrator with strong data quality, retry logic, and MCP-friendly output schemas.

Key Features

• 4 search modes: Company search, job search, domain enrichment, monitoring
• Weighted lead scoring: Configurable weights for technology match, hiring intent, recency, and company fit
• Deduplication: Merge by domain or company name, keeping highest-scored results
• Monitoring mode: Compare runs against baselines; flag new companies
• MCP-ready: Strong input/dataset/output schemas for AI agent discovery
• Pay-per-event pricing: No subscription — pay only for results

Search Modes

Company Search

Find companies using specific technologies, optionally filtered by hiring signals.

Job Search

Search job postings first, then group by company with enrichment.

Domain Enrichment

Provide a list of domains and get tech stack + hiring signal data.

Monitoring

Run a search and compare results to a baseline dataset. New companies are flagged with signals.newSinceBaseline = true.

Output

Each dataset item includes:

{
  "companyName": "Example Corp",
  "companyDomain": "example.com",
  "companyIndustry": "Computer Software",
  "companySize": "201-500",
  "technologiesMatched": [...],

  "source": "theirstack"
}

A SUMMARY record is saved in the key-value store with run stats, top industries/technologies, and webhook metadata.

Scoring Model

Lead scores range 0–100 using configurable weights:

• Technology match (40%): % of requested techs found × confidence
• Job intent (35%): Count and keyword coverage of matched jobs
• Recency (15%): Exponential decay from most recent evidence
• Company fit (10%): Size and industry alignment

Score bands: very_high (90+), high (75–89), medium (50–74), low (0–49)
