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 problem we solve
Measurement tools were built for a web where people clicked. Five things we do differently.
Affordable
Traditional attribution and MMM tools cost thousands per month, pricing out the businesses that need them most. MarSci is pay as you go.
Easy to implement
Complex setup requiring data scientists, months of configuration, and ongoing technical maintenance. MarSci runs on daily aggregates and gives results in 20 minutes.
Transparent
Black box algorithms. Most platforms do not show how results are calculated. You just have to trust them. MarSci is open source and shows every range.
Built for the new era
Users do not click anymore. Audio ads, AI search results, video first channels: click based tracking misses it all. MarSci measures channels that never get a click.
Privacy first
Cookie dependent tracking is increasingly blocked by regulations and browsers, making data less reliable every day. MarSci uses no cookies and no personal data.
Our approach
We believe marketing measurement should be available to everyone. We built the technology to make cross-channel understanding easy, actionable, and affordable.
Our platform uses only aggregated data for calculations, so any business can benefit. No personal data, no cookies, nothing to integrate.
# Daily aggregates. That is all we need.
