About Caslon Media
Caslon Media is an independent, founder-owned publishing company in Amsterdam. We build and operate reference websites: places you go to answer a specific question — which books your state assigns in ninth grade, how much water your sourdough starter actually needs, which dorm essentials your school expects — and leave knowing the answer is right.
We started with a simple observation: most reference pages on the internet are written to rank, not to be right. We run things the other way around. Every site in our network is built from a real, finite dataset with primary sources behind it. When a fact can't be verified, it doesn't go on the page. When data ages, we re-verify it and date it. It's slower. The pages are better for it.
How we operate
We're a small, deliberately-small portfolio company. Our operating rules are borrowed from the publishers we admire most: fewer, bigger, better pages instead of volume; the fastest pages we can build, because speed is respect for the reader; one honest recommendation instead of ten hedged ones; and an unsentimental approach to the portfolio — sites earn their place by being used.
The company is run by its founder, Paulo de Vries, in Amsterdam, working with occasional freelance editors and researchers. We use automation and AI-assisted tooling for data processing and drafting; not every page is read by a person before it goes live (see below). Read more in our editorial standards, and about the people behind it on our team page.
Who runs Caslon Media
Caslon Media is the company of Paulo de Vries in Amsterdam (KvK 64708101). Paulo owns and runs Caslon Media and is responsible for what it and its sites publish. Questions or corrections: hello@caslonmedia.com or the contact page.
How our sites are made
- Sources. Each site works from its own named sources, such as official reading lists, award records, manufacturer specifications or public filings. Each site's methodology page names them, and the pages link to them.
- Writing. The text is drafted with AI assistance, working from those sources. Where a site shows numbers from a dataset, the numbers come from the data, not from the AI.
- Checks. Before any site goes live, scripts check the build: for example that every Amazon link goes through the site's own tracked link page, and that no new page is too thin to be useful.
- People. Not every page is read by a person before it goes live. That is why our pages name their sources, so you can check where a fact comes from.
- Corrections. Found a mistake? Email hello@caslonmedia.com with the page link. We fix it on the page. See our corrections policy.
Paulo's name is not on individual pages of our sites: he runs the company but does not write each page himself.
Independence & ownership
Caslon Media is independently owned and self-funded — no outside investors. Our revenue comes from advertising and affiliate partnerships, and that revenue never dictates what we recommend or what our data says. See how we make money.
The name
We're named for William Caslon, the eighteenth-century English typefounder. His letters were so effortless to read that printers had a saying — when in doubt, use Caslon — and when the Declaration of Independence was first set in type, it was set in Caslon. We claim no lineage, just a debt: type that earned trust by being easy to read is the standard we hold our pages to.
