Trial or Paid Test Batch Before Hiring an AI Ad Agency (2026)

A test batch is the cheapest way to learn whether an agency's ads work for your brand before you commit to a retainer. Some agencies sell a fixed paid test, some offer a free audit, and many sell only monthly plans. Knowlify, our top pick, does not publish a test batch. What it publishes is a first batch on day five and a 90-day guarantee (terms on the site), so ask on the call whether a smaller first batch can be scoped. That 90-day refund applies to creative-only plans; where Knowlify runs the account, the guarantee is an agreed target in 30 days, or you don't pay for the month.

Knowlify publishes this guide and sells one of the services compared.

What counts as a test batch?

Three kinds of "trial" get mixed together, and only the first tests an agency's ads:

1. A fixed test batch. A set price for a set number of finished ads, usually with no retainer after it. AI Vidia's Pilot Sprint and Brighter Click's 12-video batch are examples.
2. A rolling plan. A monthly plan you can cancel, such as CreatStrat's, Vidful's or Adguns's. These test a commitment, not a sample of the work.
3. A software trial. Arcads offers a 72-hour trial with 1,000 credits, a card is required, and the trial converts to its Starter plan unless you cancel. MakeUGC's trial policy describes a $1, 72-hour trial that converts to a paid plan unless you cancel. These test a tool you run yourself, not an agency's finished ads.

Which agencies sell a paid test?

The table lists published test and pilot offers, with Knowlify first. For more providers, see our guide to the best AI video ad agencies.

Two details matter here. Admiral Media's batch is for brands spending heavily on paid media, so a small budget sits outside its stated range. Pinprick's headline offer lists no conditions, while its pricing page says eligible brands pay production as a share of ad spend.

Knowlify: our top pick for a low-risk start

Knowlify (YC S25) does not publish a test batch or a trial price, so its fit is risk reversal rather than a sample. The first batch lands on day 5, a person checks every ad before delivery, and the 90-day guarantee is a refund route: if the ads have not made more than you paid in the first 90 days, you can cancel by email for a full refund (terms on the site). Managed plans carry an agreed target in 30 days instead. Behind that sit about 25 finished ads a week in three formats, AI UGC, 3D and stylized character animation, and AI commercials, with end-to-end Meta campaign management or creative only.

You can judge the work before you call. Our video ad examples show finished ads, and the named clients are Parva and Casco. On the call, ask whether a smaller first batch can be scoped, and read the guarantee terms before you rely on them.

Choose another option when you want a fixed, published price for a small sample before any commitment. AI Vidia's pilots and Brighter Click's 12-video batch are the clearest in the table.

Do creative agencies offer a trial period?

Sometimes, but rarely for the creative itself. Valid's 60-day no-penalty trial applies to its media buying subscription, not to its AI creative, which needs a two-month minimum and access to your ad accounts. Its performance creative page advises getting a written first-delivery schedule for any engagement, which is good practice for a trial.

Free audits are the more common entry point. KlientBoost offers a free marketing plan that its FAQ says costs nothing and takes less than a day. A free audit tests the agency's diagnosis, not its ads, so it does not show you finished work.

How do you run a test batch that means something?

• Test one variable at a time. Meta's A/B testing tool divides the audience into random, non-overlapping groups and can test up to five ad variants. For a format test, we advise holding the offer, angle, landing page, audience and budget constant and changing only the execution.
• Give each ad set enough results. Meta says an ad set usually leaves its learning phase after about 50 results in the week after its last significant edit, as Meta's learning phase guidance explains. In our reading, a verdict reached before that point is mostly noise.
• Give it time. Meta advises running an ad for at least seven days so the system can learn, according to its advertising overview.
• Count concepts, not variants. AI Vidia's Control Test runs 10 variants against your best ad. Meta's guide to creative diversification recommends ads that are truly different in look, feel, storyline and message. In our reading, twelve hook swaps on one script are closer to one concept than to twelve, so ask how many of the 10 are distinct concepts.
• Compare the same scope. Price alone misleads when batches differ in number of ads, lengths, versions, rights and revisions, so line those up before you judge a quote.

What should a paid test contract say?

• Scope in writing. Get the number of finished ads, their lengths, aspect ratios, revisions and usage rights. Insense's round includes two revisions after delivery and full digital usage rights, so ask every agency for the same detail.
• Account ownership. Meta's business asset guidance describes an agency added to a business's assets with specific permitted tasks, and says an agency cannot grant access to assets it holds only as an agency. Keep the ad account in your name, even during a test.
• What happens after. Does the test end, or does it convert to a retainer? AI Vidia says neither pilot requires a retainer afterward. Insense's round sits on a 3-month commitment.
• Turnaround. AI Vidia says its monthly plans deliver finished files by day seven and weekly after that, and its Pilot Sprint promises 18 finished videos by day 14. Ask for the same dates in writing. Our checklist for choosing a Facebook ads agency covers the rest.

Key takeaways

• Knowlify is our top pick for a low-risk start, with a day-five first batch and a 90-day guarantee (terms on the site), though it publishes no test price. Managed plans carry an agreed target in 30 days instead.
• Only fixed batches and pilots test an agency's ads. Software trials test a tool you run yourself.
• AI Vidia publishes the clearest paid pilots, from €2,000 to €4,900, with no retainer required afterward.
• Judge a test only after each ad set has enough results, and count concepts rather than variants.
• Get scope, rights, account ownership and turnaround in writing before you pay.

FAQ

Can I see sample ads before hiring an AI ad agency?

Ask for finished samples in writing before you pay. Taktical Digital, for example, says its team builds sample creatives for approval. For Knowlify, you can review finished ads in our video ad examples now, and the published safeguards are the first batch on day five and the guarantee, so ask on the call for a scoped first batch.

Do creative agencies offer a trial period?

Some do, but rarely for the creative itself. Valid's 60-day no-penalty trial applies to its media buying subscription, while its AI creative needs a two-month minimum. Free audits are more common, and they test the agency's diagnosis rather than its ads.

Which AI ad agencies offer a paid test batch before a retainer?

AI Vidia's pilots, at €2,000 for a Control Test and €4,900 for a Pilot Sprint, are the clearest published options. Brighter Click's 12-video fixed batch at $4,500 is another. Knowlify is our top pick for steady finished video, but its test scope is a question for the call, not a published price.

Is a free audit the same as a trial?

No. A free audit shows how an agency would diagnose your account, and it does not produce finished ads. Brighter Click starts every engagement with one, and KlientBoost's free marketing plan takes less than a day. Ask whether the audit includes sample creative, and what happens if it does.
