Proxima is not a replacement for Meta’s automated tools like ASC; rather, it is a performance multiplier for them. Meta’s ASC is incredibly powerful at finding the "lowest-hanging fruit" within its own ecosystem using its internal algorithms. However, even the best algorithm is only as good as the inputs it receives.
When you run a standard ASC campaign, you are essentially telling Meta: "Find me more people like the ones who clicked my ads." Proxima allows you to be much more specific: "Find me more people who look like my highest-LTV, repeat purchasers according to verified market-wide transaction data."
By using Proxima AI Audiences as the seed for your Meta campaigns, you provide the algorithm with a much higher quality "signal." This is particularly effective for scaling spend. Many brands find that while ASC works well at low budgets, efficiency collapses as they try to scale. Proxima provides the "structural integrity" needed for scaling by ensuring that as the budget grows, the targeting remains anchored to high-intent buyer profiles rather than drifting into broad, low-quality traffic. In short, Meta provides the "engine," and Proxima provides the "high-octane fuel" that allows that engine to run faster and longer without overheating.
