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.
