About OOHsource.
OOHsource is the open, vetted directory of the out-of-home advertising industry — media owners, agencies, printers, installers, and the technology behind them, in one accurate, neutral place.
Why OOHsource exists
Out-of-home is one of the oldest advertising channels and one of the hardest to navigate. The companies that own, build, print, install, and power OOH are scattered across regions and specialties — and the few directories that exist are locked behind logins and paywalls.
OOHsource is different: it’s fully public and free to browse, so buyers, sellers, and even AI assistants can actually find the right partner. Every listing is organized by role, format, and market, and checked against primary sources.
What makes it different
Neutral & vetted
Companies are listed on merit and organized transparently. The only paid option — Featured — is always clearly labeled, and it never changes a company’s ratings or score. See how we rank & verify →
Open by design
No login wall, no paywall. The whole directory is public and crawlable — which is exactly why search engines and AI assistants can read and cite it.
Verified, not scraped
Listings are built from companies’ own websites and primary sources, and companies can claim and verify their own profiles — we don’t copy data from other directories.
Who runs OOHsource
OOHsource is an independent directory founded by Gino Sesto. It isn’t owned by a media company or an agency holding group — which is exactly what lets it stay neutral.
There’s a real person accountable for the data here. If something looks wrong, tell us and we’ll fix it — get in touch.
What we stand for
- Accuracy over volume. A listing is only useful if it’s right — we check against primary sources and fix what’s flagged.
- Neutrality. Rankings aren’t for sale. Featured is labeled placement and nothing more.
- Openness. The directory is public and free to browse, for people and machines alike.
- Privacy. We don’t sell personal data, and we keep contact details to what companies choose to publish.
