Media Mix Attribution
Fospha's Media Mix Attribution (MMA) pairs full-funnel attribution with media mix modeling. You get daily results across every channel and everywhere you sell, plus the tools to plan and forecast, so you always know where to go next.

The source of truth enterprise brands run on. It measures the total funnel across every channel you run and every place you sell. You spot more opportunities, more often.




Built over the last 10+ years in partnership with enterprise teams, MMA has evolved for modern marketing. It's shaped by the decisions teams make every day.
MMA starts where last click ends and builds the full funnel. It combines data validation, click measurement, post-purchase surveys, reconciliation and impression measurement, which borrows from media mix modeling in aggregate. Typical attribution leaves gaps. MMA doesn't.
The model learns from 2 years of historic data to capture your seasonality. It retrains on the latest business context and refreshes daily. It reconciles to 100% of your revenue, so finance has a number to trust. That fixes last click missing credit and ad platforms over-crediting their own channels.
A Bayesian approach finds the marginal return of every channel, showing what your next dollar is worth at different spend levels. Then it makes it simple to build one plan across your media mix. Built from the conservative end of 5,000 plausible forecasts, it's a plan you can act on.
MMA is a proprietary model and a complete glass box. Every validation metric and model layer is visible in the platform. Your team can interrogate every channel at every stage and compare Fospha's credit with last click and ad platform reporting.
Run your daily reporting, weekly trade meeting and in-flight campaign checks from one set of trusted numbers.
Weigh social, search, CTV, retail media and marketplaces side by side, then move budget to what works.
Capture marginal return as opportunities appear, not after the next MMM or incrementality test. Then calibrate both in one view.

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 measurement 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 always-on measurement signal 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 always-on measurement signal with Daily MMM - something our competitors simply don't offer.
While platform-native dashboards miss upper-funnel impact due to signal loss, and traditional MMM lacks the speed and granularity for daily decisions, we deliver:
- The granular, ad-level measurement insights for tactical optimization
- The predictive power and total channel visibility of our Daily MMM, fairly crediting both demand generation and capture channels
Our unified approach, refined through 10+ years of working with hundreds of brands, corrects the common measurement bias toward last-touch channels - properly valuing the complete channel mix from awareness to conversion.
Fospha measures your entire channel mix, from brand awareness to conversions, giving every channel fair credit using privacy-safe Daily MMM.
We cover everything that drives growth - across web, app, and Amazon - and unify it into a single, unbiased view.
What sets us apart:
- Halo Effect: Reveal how Meta, TikTok, and Google ads drive sales on Amazon - with unified ROAS across DTC and marketplace
- TikTok Shop: Track in-app and on-site purchases together, giving you full visibility into TikTok performance beyond what Google Analytics can capture
- App Sales: We model app and web sales separately to reflect how customers behave on each platform
