KAK Cortex vs Northbeam

Which is better? They measure different things. KAK Cortex sends real-time behavioral signals to Meta to improve ad performance immediately. Northbeam measures incrementality across channels to answer "how much revenue did this channel actually drive?" Cortex is tactical optimization; Northbeam is strategic understanding.

Feature Comparison

Who Should Use KAK Cortex?

KAK Cortex is for brands optimizing Meta Ads right now. Choose Cortex if:

• You spend $5K+ monthly on Meta and need immediate ROAS improvement
• Your pixel captures <60% of behavior (post-iOS 14 is common)
• You want Meta to optimize on 70+ behavioral signals, not standard events
• You need real-time intent scoring to segment audiences automatically
• Your time horizon is weeks/months (immediate ROI improvement)

Example: A skincare brand with $25K/month Meta spend deployed Cortex and saw ROAS improve from 1.6× to 3.1× within 60 days by giving Meta 70+ enriched behavioral signals.

Who Should Use Northbeam?

Northbeam is for brands that need to understand true channel ROI. Choose Northbeam if:

• You run campaigns across Meta, Google, email, and other channels
• You need to know the incremental revenue from each channel (not last-touch)
• You want to run holdout tests to isolate channel impact
• Your time horizon is monthly/quarterly (strategic budget allocation)
• You need marketing mix modeling to optimize budget across channels
• You want to isolate true ROAS by controlling for organic conversion rates

Key difference: Northbeam answers "Is this channel actually working?" Cortex answers "How do I make Meta optimize better right now?"

Tactical vs Strategic

The Verdict

For quick wins: Choose KAK Cortex. You'll feed Meta better behavioral data immediately and see ROAS improve within 30-60 days.

For strategic clarity: Choose Northbeam. You'll understand which channels are actually driving incremental revenue and how to allocate budgets long-term.

Smart brands use both: Cortex optimizes Meta performance week-to-week. Northbeam measures true channel ROI month-to-month. They're complementary — one improves execution, the other informs strategy.

Understanding Incrementality

Here's why Northbeam's incrementality testing matters: Last-touch attribution gives you a distorted view of channel performance. If your organic conversion rate is 2%, and Meta brings traffic that naturally converts at 2%, Meta's last-touch ROAS looks better than it actually is.

Northbeam runs holdout tests (pausing channels for groups of users) to measure true incremental impact. This answers: "If we turned off Meta entirely, how much revenue would we actually lose?"

Cortex doesn't do this. Instead, it focuses on giving Meta better signal quality so the algorithm optimizes smarter within the channel. It's about short-term performance, not long-term measurement.
