FAQs

Can I access Fospha data through my AI tools?

Yes. Fospha MCP connects your Fospha measurement directly to AI tools like Claude and ChatGPT - so you can ask questions about your performance data in plain language and get answers back in seconds, using the same data that's in your Fospha dashboard. No login required.

MCP works with Claude and Cursor today, with ChatGPT and Perplexity coming next. You'll need an enterprise AI account (Claude for Work, ChatGPT Enterprise, or equivalent) to connect it.

How do I know your model is accurate?

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.

Is Fospha privacy safe?

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No third-party cookies or user-level tracking: Our model doesn’t rely on personal identifiers or outdated tracking methods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

How is Fospha different from traditional MTA, MMM, and other marketing measurement solutions?

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.

Which channels does Fospha measure?

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

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