Why do media buyers run out of things to test?
Because creatives tire faster than a team can brainstorm new ones. By week three a client's best Meta ads lose steam, and the next batch decides the month. Without a reliable source of proven angles, that batch is guesswork: ideas nobody has tested, picked by taste instead of by what the market already pays for.
On Meta, the clearest public signal of what converts is time. An advertiser who keeps paying for the same ad for 30, 60 or 90 days is telling you it works. The Meta Ad Library shows those ads, but you search page by page and read the duration off a start date.
Pantheon does that sorting for you, in the markets your clients sell in, and tells you why each ad works before you spend a euro testing its angle.
How media buyers use Pantheon, step by step
- Add the client's offer. From their website link Pantheon prepares the Offer Brief, Avatar and Brand Voice it uses for every search and every variant.
- Spy on the client's competitors. Competitor Spy pulls every active ad of a Facebook page, and weekly monitoring emails you when they launch new ones.
- Start the radar for the offer. The agent searches Meta in the countries and language you choose, keeps ads active for 7 to 90 days (your pick) and drops e-commerce and off-topic pages. Results come in three lanes: the client's market, the best in the world and ideas from other industries.
- Read why an ad works before you test its angle. Ads Intelligence gives the audience's awareness level, which of the 22 persuasion mechanisms it uses and whether the landing page keeps the ad's promise.
- Turn the angle into creatives. The Adapter writes 3 variants of the chosen ad for the client's offer. It transfers the mechanism and never copies the text.
On European ads you also get the reach, countries and age and gender bands that Meta publishes for the EU: a useful hint of who a competitor is going after. And the ads you find stay in Pantheon, with their media, after they disappear from Meta.

What Pantheon doesn't do for media buyers
Pantheon is a research and creative tool. It doesn't connect to Ads Manager, doesn't touch budgets or bids and doesn't report on your campaigns. It covers Meta only (Facebook and Instagram): no TikTok, Google or programmatic.
If your clients sell physical products, Pantheon is the wrong tool. It removes e-commerce and dropshipping from its library, radar and agent by design, and works for media buyers whose clients sell coaching, training, consulting, info products or B2B services. Our ad spy tools comparison lists options built for e-commerce.
The curated public library is mostly French pages plus some US ones today. The radar's agent, on the other hand, searches the countries you set.

Pantheon for media buyers: frequently asked questions
Is Pantheon a media buying platform?
No. Pantheon doesn't buy media, set bids or manage campaigns. It helps you decide which Meta ads to test next: it finds ads that keep running in your client's market, explains why they work and writes new variants for the client's offer.
Can I use Pantheon for several clients?
Yes. Competitor Spy and weekly monitoring work on any Facebook page from the Starter plan. Pro includes a radar for 1 offer; Scale gives 5 offers, a 3,000-ad agent and a private Ads Library of 10,000 ads a month.
Does Pantheon show how much a competitor spends?
No. Meta doesn't publish spend for commercial ads. Pantheon relies on how long an ad has been running, how many variants are live and, for ads shown in the EU, the reach Meta publishes.
Is there a free trial?
Yes: 5 days, no card, with credits for Competitor Spy, Inspiration Search, ad analyses and the Adapter. The radar and the agent start from the Pro plan.
