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.

What you are looking at. Facebook reports a $7.79 cost per purchase. The causal model finds $452.57, because most of those purchases would have happened anyway. Google non-brand search reports $57.97 and actually costs $0.95. That is the difference between a dashboard and an answer.

Our approach

We believe macroeconomic models should not be only for Fortune 500 companies. Every marketing manager deserves to see how their channels work together.

We believe marketing measurement should be privacy first. That is why we only use aggregated information. Nothing to integrate, no personal data, no cookies.

We believe you deserve to know what to do next. Not another dashboard. A clear recommendation you can act on this week.

# Daily aggregates. That is all we need.

How it works

Four steps. Only two of them are yours.

  1. Log in

    Create an account and log in. No credit card, no sales call, no setup project.

  2. Connect your data

    With an API connection to Meta, Google, TikTok, Shopify and more, or without one: upload a CSV of daily aggregates.

  3. We run the models

    Attribution and the marketing mix model run on our back end. Nothing to install, nothing to configure.

  4. You get notified

    When everything is set up you get an email and your results are waiting. You do not have to do anything in between.

Why MarSci

  • Multiple models, not just one

    We are open-source and we let you run different measurement approaches side by side. No single model that only benefits us. You compare, you decide.

  • Designed for actions

    Most tools give you charts. We give you clear recommendations: which channels to increase, which to cut, and how much to shift. Built to change what you do on Monday morning.

  • Results in minutes, not months

    Upload your data and get answers straight away. No onboarding calls, no setup projects, no waiting for a data team. You are in control from day one.

What our partners say

“We were looking for a media mix analysis for a while. As a travel company and with a complex business model, none of the available solutions could answer our business needs. MarSci managed to not only offer a smooth onboarding process but also to answer which marketing channel is more impactful to our very long booking window.”
SStef, Co-founder and Managing Director, travel company
“MarSci has transformed the way we measure and manage our marketing performance. For the first time, we have a clear view of how our online campaigns and offline sales activities work together to drive results. Their platform helped us identify new opportunities, optimise our budget allocation, and make data-driven decisions with confidence. It has been a true step change in how we approach growth.”

What the 30 minutes cover
  1. Your setup 5 min

    Which channels you run, what data you already have, and the decision you are trying to make.

  2. 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.

  3. 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.

Why book it
  • 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.
