Meta ads agency for brands spending $100K+ a month
Defined Chase runs Meta ads (Facebook and Instagram) for brands spending $100,000 to $10M+ a month that want to scale without CAC running away. At this spend Meta is a creative and signal problem: we run a steady creative testing engine, send real revenue back through the Conversions API, and move budget on marginal CAC. Our team has managed $100M+ in ad spend over 13+ years.

4.9★★★★★across 30+ client reviewsWho it is for
We are a fit for a small number of teams, and we say so on the first call.
Good fit
- E-commerce, apps, SaaS and B2B brands spending $100K+ a month, or close to it
- Accounts where CPA rises every time budget goes up
- Teams that cannot produce enough creative to keep up with spend
- Brands running Meta in several countries
Not a fit
- Budgets under about $20K a month: start with the free roadmap
- Teams that will not change the offer or landing page
- Anyone who wants boosted posts, not a system
What we do
Six things decide whether more budget makes more profit.
A testing engine
New angles every one to two weeks, 10 to 20 ads per ad set, refreshed before fatigue and judged on cost per new customer.
Conversions API done right
Server-side events, deduplication and offline conversions, so Meta learns from paid orders, not page views.
Fewer, bigger campaigns
Consolidated campaigns and Advantage+ where it helps, so the algorithm gets enough data to learn.
Scale on marginal CAC
Budget goes up in steps the account can absorb and comes down when the last dollar stops paying back.
Ad, page and offer aligned
Landing pages and offers tested on the paths with the most spend, so the click turns into revenue.
Platform vs backend
Meta-reported results reconciled against your store or CRM every month.

FAQ
Why does Meta CPA rise when I scale?
Because each extra dollar reaches people who are less ready to buy, and creative fatigues faster at higher spend. The fix is more creative angles, better signal through the Conversions API and budget steps judged on marginal CAC.
Do you produce the creative?
We run the creative strategy, briefs and testing. Production happens with your team or our partners, depending on volume and format.
Do you use Advantage+ campaigns?
Yes, where the data supports it. We keep enough structure to read what works, and we exclude existing customers when the goal is new ones.
How much does a Meta ads agency cost?
At Defined Chase the fee is from 15% of ad spend with a $15,000 monthly minimum, and you pay Meta directly. The free Growth Map Call comes first.
Are you a Meta Business Partner?
Yes. Defined Chase is a Meta Business Partner.
