About

Every commercial AI company worth knowing — from garage startups to trillion-dollar giants.

Ludbee is a directory of the companies that sell artificial intelligence — 426 of them, from two-person startups to the largest listed companies in the world — and of the products they actually ship. Every company has its own page, every product has its own page, and the whole set is one grid you can filter, sort and search.

It exists because the question “who actually makes this, and how big are they?” is surprisingly hard to answer. Vendor pages sell, press coverage is episodic, and the list posts go stale the week they are published. A directory is a boring answer to that question, which is the point: it is meant to be scanned, cited and linked to.

What is in it

• 426 companies, each with funding, valuation, headcount, founding year, headquarters and category, across 4 categories: Application, Foundation Models, Hardware, Infrastructure.
• 1,892 products across 420 of those companies, each with what it does, what kind of thing it is, and how it charges.
• One Related companies rail on every company page — every row states what the two companies share and where they diverge, and carries badges saying what that claim rests on. Some rows are sourced from someone naming the two as alternatives, on 235 companies so far; the rest are computed from what their products do. Each row says which it is. Methodology explains why it is one rail and not two.

Figures come from public sources and are dated on every record. Methodology says which sources, how the default ranking works, and what a blank means.

What is not in it

• Reviews, scores and star ratings. This site records what a company is and what it sells. It does not tell you which one is good.
• Paid position in the ranking. Not now and not later. No payment changes a figure, a ranking, a peer set or the order of any list. If ordering were for sale, every recommendation here would be unfalsifiable — you could never tell whether a company was listed because it fit or because it paid. Should the site ever take vendor money, it will be for something that has no effect on ordering, and Terms will say what it is before the first sale.
• Everything. The directory is a snapshot, not a census. Companies are missing, and the fastest way to fix that is to tell us.

How it is built

Plain HTML, CSS and JavaScript. No framework, no tracking scripts, no third-party requests: logos and flags are served from this domain, and the dataset is a handful of JSON files the page reads. Pages are written ahead of time rather than assembled when you ask for one, which is why it loads quickly on a phone.

The dataset was collected in August 2026. There is no automatic refresh yet, so corrections from readers are the fastest route to a fix — every company and product page carries a link for exactly that.
