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.

George, PhD
Founder. Marketing scientist

Boi, PhD
CTO. AI engineer
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.

Four things other tools get wrong. What MarSci does instead.
Just authenticate, done
Other tools mean ETL contracts, engineering time and lock-in. Weeks before you see any value. With MarSci you connect an account with a single click and we handle the rest. No field mapping, no configuration, no engineering.
Zero configuration
Most tools need custom pipelines, field mapping and ongoing maintenance just to keep data flowing. We normalise fields, align dates and clean your data automatically. Raw accounts to a ready dataset in minutes.
Organic and paid, one dataset
Most platforms ignore SEO, social and content signals, so you undervalue organic momentum and overspend on media. MarSci pulls organic and paid side by side, in one table.
Your data, your drive
Most platforms force you onto their servers and bill you for storage. We store the clean dataset back on your own drive, or host it in the EU if you prefer. No warehouse fees, no lock-in.
Start with what you already have. Add more over time.
Every connector is one click. Anything else comes in as a CSV and is mapped to our schema in minutes.
Organic
Paid
Warehouses and CRMs
Need something else? We support CSV uploads and can map fields to our schema in minutes.
Three ways to use your connected data
Offline analysis
Connect your accounts and receive a clean CSV by email. Analyse locally in Excel, Python or R.
MarSci dashboards
Plug into the MarSci visualisation layer. Compare channels, spot trends and track KPIs instantly.
Run attribution and MMM
Use the same connected data to run causal attribution and Marketing Mix Modeling. No extra setup.
How it works
Five steps from zero to a clean, ready-to-use dataset. Only the first two are yours.
Pick your data sources
Any combination of sales, organic, paid and CRM connectors from the list.
Authenticate your accounts
One click to connect. Secure OAuth. No cookies, no personal data involved.
We process your data
Fields normalised, dates aligned, third-party controls added. Nothing to configure on your end.
Get a clean dataset
A ready-to-use CSV in your inbox, or a hosted table that refreshes itself. Your choice.
Analyse anywhere
Use MarSci dashboards, run attribution, launch a Marketing Mix Model, or take the file elsewhere.
Your choice: own it, or let us run it for you
Most platforms force you onto their servers. We give you two options.
Hosted on your side
We clean and normalise your dataset, then store it back on your own drive. No cloud fees, no lock-in, no dependency on us.
- Your data stays on your own drive
- No warehouse or storage bills
- Use it inside or outside MarSci
Best when your team already works in Excel, Python or a warehouse of its own.
