Questions
Straight answers.
Exactly what to expect from working with Keynes.
How is this different from linear TV buying?
Linear TV and CTV may share "TV" in the name, but they work very differently. Linear TV buys are typically based on a show's audience demographics and measured using panels. Keynes takes an audience-first approach, reaching the right people regardless of what they watch. Using intent and interest signals, Keynes values and bids on every impression based on its expected return—reducing waste and improving MER for brands.
How fast can we see results?
Most brands begin seeing results within the first few weeks, with full performance typically reached in two to three weeks. The long-tail impact usually becomes apparent after 60 days.
Is there a minimum spend to get started?
There’s a practical floor for the data to be statistically useful, but it’s lower than most streaming platforms require. We’ll tell you honestly if your budget isn’t there yet.
Can Kortex work alongside our existing agency?
Yes. Kortex sits underneath whoever is buying media — agency or in-house — as the measurement and optimization layer, not a replacement for the relationship.
What do you need from us to start?
All we need is access to your existing performance data. We'll handle the integration, modeling, and campaign build—doing the heavy lifting for you.
