Core measures daily, cross-channel performance down to the ad level - giving teams a trusted view for reporting, optimization and planning.


The most actionable full-funnel Media Mix Model (MMM) that quantifies the impact of every impression, view, and click down to the ad level.




Unlike traditional MMM tools, Core delivers strategic insights daily - built to be operationalized across the business and for automation.
Core’s daily Bayesian MMM measures true upper-funnel impact - capturing the performance MTA can’t - for consistent, like-for-like channel comparisons.
Core combines deterministic, correlative and causal models to solve different measurement challenges and uncover real incremental performance.
The model updates every day with live data on promotions, offline marketing and market shifts - keeping outputs aligned with reality.
Every validation metric and model layer is visible in-platform, helping you verify accuracy and build trust internally.
Turn every impression, view, and click into measurable impact.
Built on Fospha’s Bayesian MMM, Core measures the total impact of Meta, TikTok, and YouTube across the full funnel - including lag effects and offline calibration.
While traditional MMMs update quarterly, Core delivers fresh, modelled insights every day, balancing speed, scope and rigour so you can act with confidence.
See what truly drives growth.
Drill down to ad and creative performance with Bayesian precision, turning high-level MMM outputs into daily, actionable optimization.

Before Core, we were stuck in short-term measurement cycles. We couldn’t prove the revenue impact of the budget we were already allocating to upper-funnel campaigns, let alone ask for more.

We take accuracy seriously—our model undergoes daily quality checks to ensure reliable, fair attribution you can trust. Here's how we ensure accuracy:
- Data Validation First: Before anything enters our model, we verify your tracking is consistent across platforms, identify any gaps between channels, and run daily checks to confirm outputs align with expected patterns.
- Historical Back-Testing: We prove our value by showing how our model would have accurately predicted your past performance trends—giving you confidence our recommendations are reliable.
- Outlier Capping: During major sales events like Black Friday, ad platforms typically over-claim credit. Our system automatically adjusts the outputs on high-traffic days to maintain a fair picture of what's really driving results.
Yes—Fospha is built for privacy-first measurement, today and in the future.
For 10+ years, we've led the shift away from pixel-based tracking—building our solution to meet global privacy standards like GDPR, CCPA, and iOS14+, and preparing for changes like Google’s Privacy Sandbox.
Here’s how we do it:
- No third-party cookies or user-level tracking: Our model doesn’t rely on personal identifiers or outdated tracking methods
- Privacy-first by design: Fospha combines ML Attribution with Daily MMM to restore visibility lost to privacy changes—without compromising compliance
- Proven compliance: Trusted by global brands across the US, UK, and EU, Fospha meets the highest privacy standards
Fospha uniquely combines the best of both worlds by unifying ML-enriched attribution with Daily MMM—something our competitors simply don't offer.
While traditional MTA misses upper-funnel impact due to signal loss, and traditional MMM lacks the speed and granularity for tactical decisions, we deliver:
- The granular, ad-level insights of attribution for tactical optimization
- The predictive power and full-funnel visibility of MMM to fairly credit both demand generation and capture channels
Our unified approach, refined through 10+ years of working with hundreds of brands, corrects the common attribution bias toward last-touch channels while properly valuing your entire marketing funnel—from awareness to conversion.
Fospha measures your entire marketing funnel—from brand awareness to conversions—giving every channel fair credit using privacy-safe, full-funnel measurement.
