How to Enrich a Company List with Technographic Data

Got a list of companies you'd like to enrich with technographic data? You can handle this both manually and programmatically.

If technology usage is a key factor in defining your Ideal Customer Profile, our enrichment feature helps you add technographic data to your company lists and build effective lead scoring models. Common reasons to enrich a company list:

• Account enrichment — Verify whether a company uses a specific technology to enrich accounts, segment leads, and personalize outreach.
• Lead scoring — Add technology signals to your scoring model so reps prioritize accounts that already use complementary or competitor tools.
• Hiring-based segmentation — Filter companies by the roles they're hiring for to detect buying intent before it shows up anywhere else.

Enrich company list manually

You can access the enrichment page from the Enrich item in the sidebar, or from the Enrich company list card on the Home page.

The enrichment wizard guides you through a step-by-step flow. First you choose what to enrich with, then you provide your company list — either via CSV upload or manual entry.

Compare HRIS tools or programming languages across companies in the app

If your question is “Which HRIS does each company use?” or “Which programming languages do these companies use?”, start with the category rather than guessing a vendor. The catalog calls the core HR systems category HRMS, which includes Workday, and the programming languages category Languages, which includes Python. Human Capital Management is a separate category worth checking for a broader view of HR software.

To inspect everything found in a category for one company:

1. Open the company from your company search results.
2. Open its technologies tab and use the Category filter to select HRMS, Languages, or Human Capital Management.
3. Review the technologies found, their confidence levels, and the job postings behind the evidence. Repeat for the other companies in your list.

To compare selected tools side by side across several companies:

1. Open Enrich. In the first step, restrict the Type to technologies and search for HRMS or Languages. The search also matches category names.
2. Select the individual tools you want to compare from the results. The enrichment wizard selects technologies individually; typing a category name does not automatically select every technology in it.
3. Upload your company CSV or paste the domains, then click Enrich. The results include a column for each selected technology, so you can compare the signals across your company list and export them.

Keep the distinction between enrichment and prospecting in mind: the Keyword category filter in company search narrows the companies returned to those with a matching signal. Use the enrichment wizard when you want to check selected tools across your existing list, including companies where those tools were not detected. Use the company profile's category filter, or the API example below, when you want all detected tools in that category.

Enrich company list programmatically

Use the Technographics API to look up the technologies used by a company, then attach the results to your CRM account or signup record. For a company list, send one request per company.

Look up a company's technologies

Get your API key from API settings and set it as the THEIRSTACK_API_KEY environment variable. Send a POST request to /v1/companies/technologies with the company's domain:

curl --fail-with-body --request POST \
  'https://api.theirstack.com/v1/companies/technologies' \
  --header "Authorization: Bearer $THEIRSTACK_API_KEY" \
  --header 'Content-Type: application/json' \
  --data '{
    "company_domain": "microsoft.com"
  }'

You can use company_name or company_linkedin_url instead of company_domain. You only need one of these identifiers; company names must match exactly, including capitalization.

The response's data array contains one entry per technology found. Each entry includes technology.name, technology.slug, confidence (low, medium, or high), the number of jobs mentioning it, and first_date_found and last_date_found. Keep your input company identifier alongside the response so you can join it back to your list.

Without technology or category filters, the request returns all technologies found for that company. Pagination is optional on this endpoint: leave out limit, page, and offset to retrieve the full result. An absent technology means we have no matching signal under your filters, rather than proof that the company does not use it. See how we source tech stack data for how to interpret the evidence.

Find technology and category identifiers

The catalog uses slugs, such as python and relational-databases, as filter values. Copy the returned slugs exactly; display names such as Python are not interchangeable with them.

Search the keyword catalog for a technology. Set keyword_type=technology to exclude buying intent topics:

curl --fail-with-body --get \
  'https://api.theirstack.com/v0/catalog/keywords' \
  --header "Authorization: Bearer $THEIRSTACK_API_KEY" \
  --data-urlencode 'keyword_type=technology' \
  --data-urlencode 'name_pattern=Python' \
  --data-urlencode 'limit=10'

Each item in data includes its slug, category_slug, and parent_category_slug. To browse categories, use these endpoints:

curl --fail-with-body \
  'https://api.theirstack.com/v1/catalog/keywords/categories' \
  --header "Authorization: Bearer $THEIRSTACK_API_KEY"

curl --fail-with-body \
  'https://api.theirstack.com/v1/catalog/keywords/subcategories' \
  --header "Authorization: Bearer $THEIRSTACK_API_KEY"

Categories are the broad parent groups. Subcategories are the narrower groups within them. Both endpoints return their results in data. You can pass a parent slug as the category_slug query parameter to the subcategories endpoint to browse just that group.

Use the identifiers in your enrichment request as follows:

For example, to return only relational databases found for Microsoft:

curl --fail-with-body --request POST \
  'https://api.theirstack.com/v1/companies/technologies' \
  --header "Authorization: Bearer $THEIRSTACK_API_KEY" \
  --header 'Content-Type: application/json' \
  --data '{
    "company_domain": "microsoft.com",
    "keyword_category_slug_or": ["relational-databases"]
  }'

To check Python instead, replace keyword_category_slug_or with "keyword_slug_or": ["python"]. Each _or filter accepts multiple slugs. Use the keyword_* names shown here; the older technology_slug_or, technology_category_slug_or, and technology_parent_category_slug_or filters are deprecated.

Enrich a list of companies

This Bash example requires jq. Replace the example domains with your list. It makes a request for each company and writes one JSON object per line to company-technographics.jsonl, with the input domain and the API response together:

set -euo pipefail

for domain in microsoft.com google.com; do
  jq -n --arg domain "$domain" '{company_domain: $domain}' \
    | curl --fail-with-body --request POST \
        'https://api.theirstack.com/v1/companies/technologies' \
        --header "Authorization: Bearer $THEIRSTACK_API_KEY" \
        --header 'Content-Type: application/json' \
        --data-binary @- \
    | jq -c --arg domain "$domain" \
        '{company_domain: $domain, response: .}'
done > company-technographics.jsonl

Add keyword_slug_or or a category filter to the JSON body if you only need selected technologies. For recurring CRM enrichment, store the results against the company domain or LinkedIn URL and handle failures using the API rate-limit guidance.

Return the HRIS tools or programming languages used by each company

Use keyword_category_slug_or to return all detected technologies in the categories you choose. These are subcategory slugs from the catalog:

For example, list the technologies in HRMS before running enrichment:

curl --fail-with-body --get \
  'https://api.theirstack.com/v0/catalog/keywords' \
  --header "Authorization: Bearer $THEIRSTACK_API_KEY" \
  --data-urlencode 'keyword_type=technology' \
  --data-urlencode 'category_slug=hrms' \
  --data-urlencode 'page=0' \
  --data-urlencode 'limit=100'

The catalog response includes pagination metadata; increment page if more results remain. This tells you which tools belong to the category, while the enrichment request tells you which of them were detected for a company.

The following Bash example queries HRMS for each company and saves its matching tools, confidence, and evidence dates. It requires jq and the same API-key environment variable as the examples above. Replace the domains with your own list, or change categories to '["languages"]' to compare programming languages:

set -euo pipefail

categories='["hrms"]'

for domain in microsoft.com google.com; do
  jq -n --arg domain "$domain" --argjson categories "$categories" \
    '{company_domain: $domain, keyword_category_slug_or: $categories}' \
    | curl --fail-with-body --request POST \
        'https://api.theirstack.com/v1/companies/technologies' \
        --header "Authorization: Bearer $THEIRSTACK_API_KEY" \
        --header 'Content-Type: application/json' \
        --data-binary @- \
    | jq -c --arg domain "$domain" '{
        company_domain: $domain,
        technologies: [.data[] | {
          name: .technology.name,
          slug: .technology.slug,
          category_slug: .technology.category_slug,
          confidence,
          jobs,
          first_date_found,
          last_date_found
        }],
        metadata
      }'
done > company-category-technographics.jsonl

Each line retains the company domain, including responses with an empty technologies array. Treat an empty array as no matching evidence and check the response metadata for truncated results before treating the lookup as complete.

A company may mention several HR systems or programming languages. Use confidence, job counts, and recency to assess the evidence; do not automatically label the first result as the company's only or current HRIS. The generic buying intent topic HRIS identifies mentions of that product category, but does not name the vendor. To identify the tool, query the technologies in HRMS as shown above.
