Marin Istvanic joins Scalability School for a deep tactical session on what it actually takes to scale e-commerce brands to nine figures with paid media on Meta. Marin is one of the most hands-on media buyers in the DTC space, managing upwards of 5 to 7 million dollars a month in ad spend across his agency clients and his own internal brand (and this episode reflects that).

The conversation launches right into the hard hitting questions with the debate around ABO versus CBO and when each actually makes sense. Marin's full whitelisting flywheel (300+ influencer profiles, authority pages, dark posts running through multiple handles in the same session), cost cap weekend scaling and what he calls the "gladiators arena" ad set, how he uses different attribution settings as a signal to Meta that a campaign is structurally different, and why he still manually picks every thumbnail across all his accounts. He also shares how he used AI to synthesize his full YouTube library into a 50-page media buying philosophy document and then how he fed his top-spending ads into a landing page template that outperformed the control by 10%.

Key Takeaways

• ABO vs. CBO - is the debate actually settled, or does the right answer depend on something most people never measure?
• Is whitelisting dead - or are you just running it wrong?
• What does a "cost cap weekend scaling" actually look like in practice — and how to spend $25K on a Saturday without blowing up your CPA?
• How changing this window actually tells Meta this is a different campaign.
• Why Marin still manually picks every thumbnail - If the "hacks" everyone is chasing are mostly noise, this is what actually moves the needle at scale.

Host Brad flies solo to walk through exactly how his team structures Meta creative testing across eight figures a year in ad spend. The episode is a tactical follow-up to a previous episode with Phil, prompted by a viral Twitter thread Brad posted on the same topic.

The core philosophy: stop trying to outthink Meta's algorithm on budget allocation. Instead, run a single CBO campaign per product or offer, treat ad sets as simple folders (not audience segments), and let Meta decide where the money goes. Brad backs this up with real ad account screenshots, shows why a higher-spending campaign with a lower ROAS can actually be healthier than it looks, and closes out with answers to the most common follow-up questions he received from the community.

Key Takeaways

• Why Meta's algorithm is smarter than you at deciding which of your ads deserves more budget and what that means for how you should structure your campaigns.
• The single reason you need to stop creating more ad sets and start stacking all your ads in one.
• Your top-spending ad set has a lower ROAS than the one barely getting any spend, does that mean you're burning money, or is Meta showing you something you're missing?
• The truth behind what actually happens when you pull it into an ABO to force-test it.
• How do you build a creative testing system that generates consistent weekly output without needing a huge production budget or team.
• What "spend is a signal" actually means for your creatives and how you should decide when to turn an ad off (You might actually be turning them off too early)
• Is splitting your account into a testing campaign and a scaling campaign helping you, or just adding complexity that slows down Meta's learning?
• How new visitor percentage and frequency metrics should change the way you interpret your campaign's ROAS.
• The actual risk of running ads to two completely different customer personas inside the same ad set on broad targeting.
• How to tell when it's time to question your creative quality versus just staying patient with your launch cadence.
