Marketing Mix Modeling, easy to run, without the price tag
Run a model in minutes with smart defaults, or tune every hyperparameter. Meridian from Google or Robyn from Meta, your choice. No coding, no data team, no six-figure invoice.
- Run a model in minutes, or fully customise it
- Meridian (Google) or Robyn (Meta), both open source
- AI explains your results in plain language
- No coding, no data team required
One model, three screens. Click a tab, or drag the budget slider in the planner. Example account.
Your call is with the people who built the models
There is no sales team at MarSci. When you book a call you speak with the founders, on your channels and your numbers.

Your setup 5 min
Which channels you run, what data you already have, and the decision you are trying to make.
Live walk-through 15 min
We open the toolkit on a real dataset: the journey map, causal attribution, the mix model, and what the recommendations look like.
Your first run 10 min
What to upload, what you get back in 20 minutes, and whether it is worth your time. If it is not, we tell you.
- You get a PhD statistician who has sat on the platform side at Facebook and TikTok, not a sales script.
- You leave with a plan for your first run, not a quote.
- No contract afterwards. Pay as you go if you use it, nothing if you do not.

The method that measures what each channel adds to sales.
MMM uses aggregated data, not cookies or user-level tracking, to show which channels work, where they saturate, and where to shift your budget.

Open-source frameworks
Meridian from Google and Robyn from Meta. Run either or both on the same data and compare. No lock-in, the models are yours.
1 hour
To first results
Connect your data, accept the smart defaults, and read the results with AI beside you. Hours, not months. No consultants.
A model in minutes, or every hyperparameter under your control
The same platform scales from a quick read to a tailored setup for complex business models.
A model in minutes
Connect your data and run with smart defaults. The platform configures adstock, saturation and priors for you, so you get reliable results without touching a single parameter.
- Smart defaults out of the box
- Guided setup, no statistics needed
- Results in hours, not months
Best for a first read, a quarterly check, or a team without a data scientist.
Get access nowCustomise your hyperparameters
Tune adstock, saturation curves, priors and constraints to match how your business actually works. Built for complex business models, long sales cycles and channels that need a tailored setup.
- Control adstock and saturation curves
- Set your own priors and constraints
- Calibrate against experiments and lift tests
Best when the model has to inform a real budget decision and someone will ask how it was built.
Talk to the teamTwo open-source frameworks, one platform
Run either or both and compare the results on the same data.
Meridian
Google’s open-source MMM framework. A Bayesian approach with built-in reach and frequency support. Ideal if you want posterior distributions and credible intervals for every channel.
Robyn
Meta’s open-source MMM library. Automated hyperparameter tuning with multi-objective optimisation. Great for fast iteration and comparing many model configurations at once.
Why run MMM with MarSci
We guide you through every step
No coding or statistics needed. The platform walks you through configuring the model, selecting variables and running the analysis.
AI helps you understand results
Once the model runs, AI explains the outputs in plain language: which channels to invest in, where to cut, and what the numbers actually say.
Do not pay a fortune
Traditional MMM projects cost tens of thousands in consulting fees and take months. MarSci gives you the same models at a fraction of the cost, ready in hours.
Open source, no lock-in
Meridian and Robyn are both open source. Your models, your data, your results. You can always take everything with you.
Privacy-safe measurement
MMM uses aggregated data. It needs no cookies and no user-level information to produce accurate results.
Compare models side by side
Run Meridian and Robyn on the same data and compare outputs. Pick the one that fits your business, or use both for validation.
When to use Marketing Mix Modeling
You have enough data volume
At least 1,000 EUR of marketing spend a day across your channels. The models need enough variation to produce reliable results.
Cross-channel strategy
You run campaigns across several channels and want to understand how they work together.
Budget pressure
You need to validate return on investment and you are ready to act on budget allocation recommendations.
What data you need
All inputs are aggregated time series. No user-level data. MarSci aligns and preprocesses everything for you.
- Target KPI: sales, revenue or conversions
- Media cost by channel: Google Ads, Meta, TikTok and the rest
- Impressions or volume metrics, recommended
- Major events and promotions
- Pricing and discounting information
# Daily or weekly aggregates. That is all we need.

What MMM tells you
Baseline and channel contribution
How much of your sales comes from baseline, meaning brand, seasonality and the economy, and how much from each marketing channel.
ROI and marginal ROI
Current returns and the incremental return of the next euro spent, so you know where to shift budget.
Cost per incremental KPI
The true cost of one additional sale or conversion per channel, with confidence intervals.
Spend against contribution
What you spend on each channel against what it actually contributes. Spot under-investment and over-investment at a glance.
