What the company lookup shows

Enter a company's domain. The lookup returns what's known about the company: name, industry, employee count and size band, headquarters, year founded, funding and the technology seen on its website, where the data has it.

It returns company data only. No people, no email addresses, no contact details.

How to read the result

The employee count comes from the company's public profile, and the size band is the range it falls in. Funding shows the last known round and the total raised. A field the data doesn't have shows as a dash, which isn't the same as zero: a company with no listed funding may simply not have announced any.

The tech stack lists tools seen on the company's website. An empty list means nothing was recorded, not that the company runs nothing.

How to use company data in outbound

  • Qualify before you prospect. Headcount, industry and funding tell you whether a company fits before you spend time finding the right person.
  • Write from facts. A recent funding round, a growing team or a tool they already run gives the first line of an email something real to say.
  • Route by size. Small companies and enterprises need different offers and different follow-up.
  • Check the tech stack. If they already use a competitor, your email is a switch pitch, not an introduction.

Why look up a company before you email

A lot of cold emails fail before the first word, because the company was never a fit. A ten-second lookup catches the obvious mismatches, such as a five-person shop on a list for an enterprise product or a company in a country you don't serve, before they cost you a send and a possible spam complaint.

The data comes from the same company database Ken's list builder searches, so a lookup here matches what you'd see when you build the list.

Questions

How do I look up a company by its domain?
Type the domain, such as acme.com, into the box above. The lookup matches it to a company record and shows the name, industry, employee count, headquarters, founding year, funding and the tech seen on its website, where known.
Does the company lookup show employee emails?
No. It returns company-level data only, with no people, emails or phone numbers. Finding people at a company and verifying their emails happens in the app, on the free plan.
Can I see what technology a company uses?
Partly. The lookup lists the tools seen on the company's website, such as analytics, chat, a CDN or marketing tools. Internal tools like a CRM rarely show on a website, so an empty or short list doesn't mean the company runs nothing.
How accurate is the company data?
Industry and headquarters rarely change. Headcount and funding move, so treat them as a recent snapshot, and check the company's own site before you quote a number in an email. A missing field means the data doesn't have it, not that the company has none.
Is there a limit on lookups?
Yes, a daily cap per visitor, because an unlimited free lookup would invite scraping. A domain someone looked up in the last week answers at once and doesn't count. For larger research, look companies up in the app.
