What is Technographic Data?
Technographic data reveals what technologies—software, tools, platforms, and infrastructure—a company uses. This includes:
- SaaS products: CRMs (Salesforce, HubSpot), marketing tools (Marketo, Mailchimp), etc.
- Development technologies: Programming languages, frameworks, databases
- Infrastructure: Cloud providers (AWS, Azure, GCP), hosting, CDNs
- Business software: ERPs, HR systems, accounting tools
- Security tools: Firewalls, authentication systems, compliance tools
Unlike firmographic data (company size, industry, revenue) or demographic data (employee characteristics), technographic data specifically focuses on a company's technology footprint.

Detailed Review of Each Technographic Data Provider
1. TheirStack — Best for Intent-Driven Technographics
TheirStack takes a unique approach to technographic data: instead of only scanning websites for frontend technologies, it analyzes millions of job postings worldwide to reveal what technologies companies are actively hiring for, implementing, and expanding.
Key Features
- Job-Based Technology Detection: Tracks 37k+ technologies mentioned in job postings, revealing not just what companies use but what they're investing in
- Intent Signals: Hiring for a technology is a strong buying signal—companies actively expanding their tech stack often need related services
- Backend Technology Coverage: Detects technologies like Snowflake, Databricks, Kubernetes, and internal tools that website scanning can't see
- Global Coverage: 171M+ job postings analyzed from 195 countries
- Company + Job Data Combined: Filter companies by tech stack OR by hiring patterns in a single platform
- Real-Time Updates: Data refreshed every minute, catching new technology adoptions quickly
- API-First Design: Clean REST API with webhooks for real-time alerts
How It Works
TheirStack's methodology is fundamentally different from traditional providers:
- Collects job postings from 316k+ sources (LinkedIn, Indeed, Glassdoor, ATS platforms)
- Extracts technology mentions using NLP and pattern matching
- Associates technologies with companies creating a real-time tech stack profile
- Tracks changes over time showing technology adoption and abandonment trends
This approach captures technologies that website scanning misses—like internal databases, data warehouses, DevOps tools, and enterprise software that doesn't expose client-side code.
Pricing
Free tier available (50 company credits/month). Paid plans from $59/month.
| Plan | Price | Credits |
|---|---|---|
| Free | $0 | 50 company credits |
| Starter | $59/mo | 1,500 API credits |

Traditional vs. Job-Based Technographics
There are two fundamentally different approaches to collecting technographic data:
Traditional Website Scanning
How it works: Crawls websites and analyzes client-side code, HTTP headers, and DNS records.
Pros:
- Can detect marketing tools, analytics, and frontend frameworks
- Works for any company with a website
- Long historical data available
Cons:
- Only detects frontend/client-side technologies
- Misses backend databases, DevOps tools, and internal systems
- Can be inaccurate if websites are cached or use CDNs
- No intent signals—just current state
Job-Based Technology Detection
How it works: Analyzes job postings to extract technology requirements and skills.
Pros:
- Detects backend technologies (Snowflake, Kubernetes, Spark, etc.)
- Reveals what companies are investing in, not just using
- Strong buying intent signals (hiring = expanding/investing)
- Covers technologies without web presence
Cons:
- Requires companies to be actively hiring
- May miss technologies in maintenance mode (not hiring)
- Newer methodology with less historical data
Which Approach is Better?
The ideal solution combines both approaches. TheirStack primarily uses job-based detection but covers 37k+ technologies, including many that traditional scanners detect. This gives you:
- Intent signals from hiring data
- Backend technology coverage
- Traditional web technology detection
- A more complete picture of a company's tech investments

Frequently Asked Questions
What is a technographic data API?
A technographic data API allows developers to programmatically access information about what technologies companies use. You can query by company to get their tech stack, or query by technology to find companies using it.
How accurate is technographic data?
Accuracy varies by provider and methodology. Website scanning is accurate for detectable technologies but misses backend tools. Job-based detection accurately shows what companies are investing in but requires active hiring. TheirStack's accuracy is typically 85-95% for technologies mentioned in job postings.
How often is technographic data updated?
- TheirStack: Every minute (job-based)
- BuiltWith: Varies by plan (daily to monthly)
- Wappalyzer: On-demand lookups
- Enterprise providers: Typically weekly to monthly
Can technographic data predict buying intent?
Yes, especially job-based technographic data. When a company hires for a specific technology, they often need:
- Related tools and services
- Training and consulting
- Infrastructure and integrations
TheirStack is specifically designed to surface these intent signals.
What's the difference between technographic and firmographic data?
- Firmographic data: Company characteristics (size, industry, revenue, location)
- Technographic data: Technologies a company uses (software, tools, platforms)
TheirStack provides both—you can filter by firmographic attributes AND technographic data in a single query.
How do I integrate technographic data into my CRM?
Most providers offer CRM integrations:
- TheirStack: API + webhooks for any CRM, plus Salesforce-compatible exports
- ZoomInfo/HG Insights: Native Salesforce integrations
- Clearbit: HubSpot integration (post-acquisition)
For custom integrations, APIs allow you to enrich records programmatically.
Conclusion
The best technographic data provider for you depends on your specific needs:
-
For intent-driven sales and comprehensive technology coverage: TheirStack offers the unique combination of job-based technology detection, real-time updates, and affordable pricing.
-
For frontend website technology detection: BuiltWith and Wappalyzer excel at identifying client-side technologies.
-
For enterprise TAM analysis: HG Insights provides comprehensive market sizing capabilities.
-
For an all-in-one sales platform: ZoomInfo includes technographics alongside contact and intent data.
TheirStack's job-based approach is particularly valuable because it reveals not just what companies use, but what they're actively investing in—a much stronger signal for sales and marketing teams.
