# Introduction

> Data you can finally trust. Full infrastructure for attribution, identity and quality – without tag manager expertise.

## What is Fidero?

We solve the trust problem in your data. Fidero is a **Stateful CDP** – it remembers each customer's context on the server, so nothing gets lost. That's how Fidero captures attribution before browsers drop it, unifies user identity across every touchpoint, and enforces governance automatically, so every team can make confident decisions on complete data.

## The problem we solve

You know this pain: you spend £500 on ads, a customer converts, and it shows up as "direct" in GA4. Marketing can't prove ROI. Product sees three different profiles for the same subscriber. Engineering wastes hours debugging why the numbers don't match. Leadership makes six-figure decisions on data nobody actually trusts.

This isn't a campaign problem - it's an infrastructure problem. Fidero fixes this.

## Complete data infrastructure across three dimensions

<CardGroup cols={3}>
  <Card title="Complete Attribution" icon="bullseye-arrow">
    Campaign context preserved everywhere – from first ad click through redirects and server-finalised conversions.

    **Target:** ≥85% of conversions with attribution context

    **Marketing sees:** 20-40% conversion recovery, GA4↔Meta↔Ads convergence
  </Card>

  <Card title="Complete Identity" icon="fingerprint">
    User journeys unified across all experiences – web, app, anonymous, known.

    **Target:** ≥90% cross-domain session linking

    **Product sees:** Full activation→retention funnels across domains
  </Card>

  <Card title="Complete Quality" icon="shield-check">
    Consent enforced universally, duplicates prevented, delivery validated – zero maintenance burden.

    **Targets:** 95% consent enforcement, 98% deduplication, 99% delivery

    **Engineering sees:** Dramatically reduced tracking maintenance

<Info>
  **Our focus: foundational data quality.** Fidero enhances your existing
  analytics and BI tools with clean, unified, enriched data – it doesn't replace
  them. Keep using your favourite dashboards and campaign tools. Fidero just
  makes the data they run on trustworthy.

## How it works: server-first architecture

Fidero captures browser signals with a lightweight SDK, then enriches every event on the server with unified identity and attribution context. You specify outcomes ("Enable Google Ads enhanced conversions"), and your configuration updates server-side automatically.

**vs traditional CDPs:** They require you to configure *how* data flows (learn GTM, configure templates, publish containers). We let you specify *what* outcomes you want. Zero tag manager expertise required.

  architecture](/guides/core-concepts/server-first-architecture) for how Browser
  State Capture, identity resolution and consent enforcement work together.
</Note>

## Who this is for

**Best fit:** Teams whose customers move across multiple domains or systems – marketing site → checkout → product, or web signup → app usage – where attribution and identity break in the gaps. Teams treating data as foundational infrastructure.

**Not right for:** Pure mobile-native apps (App Store download → in-app billing) – simpler architectures lack the multi-domain complexity Fidero is built for. Teams set on building and operating their own data infrastructure in-house. Teams seeking quick campaign fixes.

<Info>
  **The honest truth:** Fidero eliminates configuration complexity, which means
  it's not right for teams who want to build and operate their own data
  infrastructure in-house. Fidero is a long-term strategic investment for
  infrastructure-minded teams.

## Getting started

<Steps>
  <Step title="Day 0: Install the SDK (5 minutes)">
    Attribution recovery starts immediately
  </Step>

  <Step title="Day 1-7: Instrument key conversion events">
    Signups, purchases, subscriptions
  </Step>

  <Step title="Day 7-30: Add product engagement events">
    Activation milestones, retention indicators, feature usage
  </Step>

  <Step title="Result">
    85%+ attribution coverage, 90%+ identity resolution, 95%+ consent enforcement
  </Step>
</Steps>

Most B2C subscription companies achieve these targets within their first 30 days.

## Not sure if Fidero fits your architecture?

We offer a **£250 Data Infrastructure Audit** (fully refundable if you don't proceed, credited to implementation if you do).

We'll assess your completeness gaps across all three dimensions and show you exactly what improvements are possible.
