Company Lookup lets you search for any company by name or domain and instantly see their technology stack, [buying intent](/en/docs/data/buying-intent) topics, job postings, and firmographic data.

## Search bar

Click on **"Search companies..."** in the sidebar, or press `⌘ K` (Mac) / `Ctrl K` (Windows). Type a company name or domain — the dropdown shows matching results with logo, domain, industry, employee count, number of jobs, and number of technologies detected.

## Company profile

Click a result to open the company profile. The header shows firmographic data at a glance: industry, location, employees, revenue, total funding, last funding round, founded date, and funding stage.

### Technologies tab

Lists every technology detected for the company. For each technology you can see:

-   **Confidence level** (High / Low) — based on how often it appears relative to other technologies in the same category
-   **Number of job postings** where the technology was mentioned — click to view the actual jobs
-   **Date range** — when the technology was first and last detected

Use the **search box** to filter by technology name. Use the **Technology Category** dropdown to see only technologies from a specific category — for example, filtering by "Big Data as a Service" might show BigQuery mentioned 35 times (HIGH confidence) while Snowflake only 5 times (LOW confidence).

**Star** any technology to pin it to a "Starred" section at the top. Starred technologies appear first when you revisit the profile.

### Buying Intent Topics tab

Shows topics the company is actively interested in, extracted from job postings and online activity. Each topic shows confidence level, job count, and date range — same structure as technologies. Topics like "Machine Learning", "Cloud Migration", or "Data Privacy" reveal what the company is investing in beyond specific tools.

### Jobs tab

Opens a [job search](/en/docs/app/job-search) pre-filtered for this company, with the full job search experience and all available filters.

## Actions

-   **Add to list** — Save the company to a [company list](/en/docs/app/company-lists) for tracking and organization
-   **Export** — Download the full technology list as CSV or Excel
-   **API** — View the equivalent cURL command and JSON response for programmatic access
