Enter an address or a domain. We read the company's own homepage and tell you what it sells, who it sells to and how — then the tech it runs, its company record, DNS and WHOIS.
Every answer says how sure it is and what it rests on. When the site tells us nothing, we say so instead of guessing an industry.
Free, no signup. Unknown domains are fetched live, so allow a few seconds.
Checking a whole list? The company category check takes 50 domains at a time and gives you a CSV.
Certainty is a word, not a number. Nothing is forced into a category to look complete.
The homepage clearly describes the business and one niche fits. Safe to segment or route a sequence on.
The sector is certain but two neighbouring niches split the vote — a soap-and-skincare brand, a furniture maker that is also a store. Use the sector.
The site blocked us or said nothing, so this came from the company record we hold rather than the page. Coarser and older — and labelled, so you know.
Parked, blocked, or too vague, and the name is not one we recognise. Better an honest blank than a wrong industry in your CRM.
Two levels. The sector is what a CRM "Industry" field wants: Beauty & Personal Care, Software & SaaS, Food & Beverage. The niche is what a sequence is written for: a skincare brand, a salon-supply distributor, a multi-brand beauty retailer. They are different companies with different problems, and a single "Beauty" bucket hides that.
Who they sell to (consumers, businesses, both) and how: sells online, D2C brand, multi-brand retailer, marketplace, SaaS, services or agency, physical locations, premium, restricted category. A D2C skincare brand and Sephora share a sector; the model row is what tells you which pitch to send.
