Company Lookup Tool: A Practical Guide for Sales and Ops Teams

A company lookup tool takes a small input, usually a website domain such as stripe.com, and returns facts about the business behind it: name, industry, rough size, location, founding year and a LinkedIn page. Sales teams use it to qualify accounts, ops teams use it to clean CRM records, and developers use it to fill in a signup form without asking the user for ten fields. The idea is simple. The quality differences between tools are not.

Two things separate a useful lookup from a frustrating one. The first is coverage: what share of the domains you actually care about come back with a record. The second is honesty: whether the tool tells you plainly when it has no record, or fills the gap with a guess. A tool that says “not found” is far easier to build a workflow around than one that returns a confident wrong answer.

If you want to see what a domain lookup looks like in practice, BusinessMCP’s free company lookup is a concrete example. According to the page, you enter a domain and get industry, size, location, founding year and LinkedIn, the free tool is fair-use limited to 15 lookups per hour, and a domain that is not in its database returns no record rather than an invented one. The same data is available through the paid company data API at $0.02 per company found. We use it for examples because its behaviour is documented in public, not because it is the only choice. Our comparison of the best company lookup tools covers the field.

This site is organised around the questions people ask when they pick or integrate one of these tools.

• What is it, exactly? Start with how a company lookup by domain works and the explainer on firmographic data.
• What does it cost? See free company lookup tools and the notes on company lookup API pricing.
• How do I use it at scale? Read about bulk lookups and the curl walkthrough.
• What if it finds nothing? Why a domain is not found explains the usual causes.
• What do I do with the results? Ideas include sales prospecting, finding a company’s email format and searching by industry and location.

One principle runs through every article: company data is a starting point for a decision, not the decision. Employee ranges are estimates, descriptions can lag reality, and a record found for a domain says nothing about whether the company is the right fit or even still trading. Treat results as evidence you check, especially before outreach or any compliance-sensitive step.
