Incrementality Testing FAQ
Incrementality Testing FAQ
Incrementality Testing FAQ
How are you different from Fospha?
Unlike SaaS tools like Fospha, we build fully bespoke models to measure true incrementality. Our approach accounts for all spend (online and offline), non-media influences such as seasonality and competitor activity and every sales channel (including retail, Amazon & Tiktok). Our pricing stays fixed as your business grows and we don’t just deliver a platform, we provide expert people to present insights and actively help optimise your marketing spend.
This sounds great, but how much do you cost?
Our plans start at £4,000/month. That includes people building bespoke models for you, software to help you self-serve insights and hands-on consultancy to support adoption and drive impact.
Surely this takes ages to set up?
Not at all - we finalise your custom models within 4 weeks and guide you through the entire process, from ideation to delivering real business value.
I need real-time insights. Is this possible?
We provide monthly insights that account for factors like pricing, promotions, competitors, and seasonality - elements that are difficult to capture accurately in real time. The risk of getting this wrong is massive, which is why we focus on delivering robust, reliable insights that drive confident decisions.
Why work with Day1Data?
We’re a team of ex-in-house data experts who’ve delivered this solution at companies like Farfetch, Tesco, Monzo, Burberry, Meta and Sky - helping them grow efficiently. Now, we’re here to do the same for you.

How much does it cost?
Our expert-led MMM services start from just £5295 /mo. To learn more about our pricing structure, book a call or visit day1data.co.uk/mmm-cost
Do we have enough data?
12+ months of varied spend and sales data across your main channels is enough to get started with MMM.
Isn't this what my ad platforms already tell me?
Platform dashboards each claim credit for the same sale. MMM looks across all channels at once for one honest number.
Is this only for big brands?
No - most of our clients are scaling mid-sized companies. Our prices make MMM affordable to scaling companies, where big agencies would charge £500k per year.
Is the call a sales pitch?
No, our call will help us decide if MMM is the right marketing effectiveness strategy for you and give you a better understanding of what's involved.
