Picking a Meta ads agency is really one question: who decides what a winning ad is, and what number do they use to decide it? Most agencies answer with platform metrics. The ones worth hiring answer with your economics. This guide is what we'd tell a founder to look for, including when the answer isn't us.

The three jobs behind the retainer

Every Meta ads engagement is three jobs wearing one invoice: creative production, media buying, and measurement. Creative is the new targeting, so the first job matters most: ask any agency how many creatives they test per month and what their testing framework looks like. An agency that talks about audiences and budget structure before creative is optimizing the small levers.

Five questions that separate operators from production shops

One: who exactly works on my account, and how many accounts do they carry? Two: how many creatives will you test in the first month, and where do they come from? Three: what number do you report success in, and can you show me a report format before we sign? Four: what happens when an ad misses, who decides to kill it, and by what rule? Five: what does leaving look like, who owns the ad account, the creative files, and the data? Vague answers to the last one cost brands the most.

Judge the agency by profit, not platform numbers

In-platform ROAS judges an ad by its first transaction, and an agency graded on ROAS alone will happily buy you discount hunters who never return. The scoreboard that keeps everyone honest is lifetime gross profit to CAC: what the customers an ad brings in are worth over time, against what they cost. Ask how acquisition and retention connect in the agency's reporting. If the answer is that retention is someone else's department, the incentives are already misaligned.

Where we fit, honestly

We run Meta ads for eCommerce brands with creative production and email and SMS retention under the same roof, judged by the same profit scoreboard: no onboarding fees, no lock-in contracts, senior operators only. The honest fit: we work best with brands that already have product-market fit and real order volume, where the constraint is creative volume and the acquisition-retention connection. If you're pre-revenue, build organic proof first.

Frequently asked questions

What does a Meta ads agency actually do?
The real work is three jobs: creative production (sourcing creators, scripting, cutting variations), media buying (budgets, structure, scaling decisions), and measurement (deciding what counts as working). Agencies differ mostly in which of the three they treat as the main job.
How should we judge a Meta ads agency's performance?
By what the customers they acquire are worth over time against what they cost, lifetime gross profit to CAC, not by in-platform ROAS alone. Ask how they report, and whether retention shows up anywhere in their numbers.
When is in-house better than an agency?
When you have the volume to keep a senior buyer and a creative pipeline busy full time, and the patience to build the testing muscle yourself. Below that, you're hiring one person to do three jobs, and creative is usually what starves.
