Powered by Beam
Beam reveals the true incremental value of every dollar you spend - so you can scale where growth remains and cut back where it’s saturated.


Statistically rigorous forecasting that cuts waste and focuses spend on channels with the highest incremental growth potential. Powered by Bayesian modeling and back-tested for trust.



Beam uses Bayesian modeling and Fospha’s full-funnel MMM data to deliver statistically rigorous forecasts that predict the next best dollar to spend.
Beam forecasts are powered by Fospha’s complete cross-channel dataset - not platform-reported clicks - ensuring every prediction reflects true marketing impact.
Beam maps diminishing returns for each channel, revealing when growth starts to flatten and how far you can scale before efficiency drops.
Thousands of Bayesian simulations predict future performance, adapting automatically to new data, seasonality, and platform shifts, so your forecasts stay reliable, every day.
Forecast where to invest next. Beam’s refreshed saturation curves identify when channels are nearing their limit and where your next growth opportunity lies.
Beam isolates the true, incremental impact of every dollar spent - so you can rank tests by expected lift and cost, focusinf on the ones that pay back fastest.
Take the guesswork out of growth with causal, daily insights - so you always know what is driving your business incremental revenue.

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.
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
With Fospha, you measure what matters—no blind spots, no wasted budget, just smarter growth.
