# What is Nemu

> Nemu is a data platform developed to help marketing professionals, traffic managers, agencies, and companies operating in digital channels make decisions with more clarity, confidence, and results.

Our purpose is simple: bring precision and transparency to marketing performance analysis, correctly attributing results to each customer touchpoint with your brand.

## How does Nemu work?

Nemu uses **First Party Data**, captured directly through integrations with platforms like:

* Meta Ads, Google Ads, TikTok Ads, Pinterest Ads
* Google Analytics 4 (GA4)
* E-commerce platforms like Shopify and Nuvemshop
* Custom webhooks and checkouts
* Google Sheets (for automations and reports)

The central element of our system is the **[Nemu Pixel](/en/platform/nemu-pixel/nemu-pixel)**, responsible for recording, based on UTMs, the origin of visits, interactions, and conversions on your site.

<Info>
  No data is estimated or statistically modeled — everything is based on real
  and trackable information.
</Info>

## Why is Nemu data different?

When comparing Nemu data with what you see in GA4, Facebook Ads Manager, or other platforms, **differences are expected — and desired**.

This happens because:

* Platforms like Google and Meta have **their own attribution goals**, often focused on justifying their own results.
* Nemu is **independent and impartial**, offering a clear, auditable, and customizable view of the customer journey.

***

## Attribution Models

Nemu offers three **attribution models** that you can switch according to your analysis:

* **First Click** – Assigns 100% credit to the first touch. Ideal for analyzing acquisition channels.
* **Last Click** – Assigns 100% to the last channel before conversion. Useful for short-term decisions.
* **Assisted** – Shows all channels that participated in the journey, helping with the multi-touch view.

<Note>
  The results you see on each Nemu screen **depend on the selected attribution
  model**. Therefore, analysis is always contextual and strategic.
</Note>

## Reliable Data. Better Decisions.

Nemu doesn't rely on cookies. We exclusively use **First Party Data**, which ensures greater accuracy even with privacy restrictions, like iOS 14+ and third-party blockers.

Our system was created to solve exactly what tools like GA4 and Ads Manager can't: **deliver a complete and neutral view of your campaigns' real performance**.

## Why use Nemu?

* Clearly visualize **where your sales come from**
* Discover **which campaigns really work**
* **Increase your ROAS** with confidence and auditable data
* Optimize tests, budgets, and strategic decisions
