What is Fidero?

We solve the trust problem in your data. Fidero captures attribution context before browsers drop it, unifies user identity across all touchpoints, and enforces governance automatically – so every team is able to 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 waste hours debugging why the numbers don’t match. Leadership are making 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

Complete Attribution

Campaign context preserved everywhere – from first ad click through redirects and server-finalised conversions.Target: ≥85% of conversions with attribution contextMarketing sees: 20-40% conversion recovery, GA4↔Meta↔Ads convergence

Complete Identity

User journeys unified across all experiences – web, app, anonymous, known.Target: ≥90% cross-domain session linkingProduct sees: Full activation→retention funnels across domains

Complete Quality

Consent enforced universally, duplicates prevented, delivery validated – zero maintenance burden.Targets: 95% consent enforcement, 98% deduplication, 99% deliveryEngineering sees: Dramatically reduced tracking maintenance
Our Focus: Foundational Data Quality. We enhance your existing analytics and BI tools with clean, unified, enriched data – we don’t replace them. Keep using your favourite dashboards and campaign tools. We just make them trustworthy.

​
How it works: server-first architecture

Our lightweight pixel captures browser signals. Our server enriches every event 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.

​
Who this is for

Best fit: B2C subscription companies with multi-domain flows (marketing site → checkout → product). Web-first architectures OR web-to-app flows (web signup → app usage). Teams treating data as foundational infrastructure. Not right for: Pure mobile-native apps (App Store download → in-app billing) – simpler architectures lack multi-domain complexity. DIY builders wanting configuration control. Teams seeking quick campaign fixes.
The honest truth: We eliminate configuration complexity, which means we’re not right for teams who want granular control over implementation details. We’re a long-term strategic investment for infrastructure-minded teams.

Getting started

1

Day 0: Install pixel (5 minutes)

Attribution recovery starts immediately
2

Day 1-7: Instrument key conversion events

Signups, purchases, subscriptions
3

Day 7-30: Add product engagement events

Activation milestones, retention indicators, feature usage
4

Result

85%+ attribution coverage, 90%+ identity resolution, 95%+ consent enforcement
Most B2C subscription companies achieve these targets within their first 30 days.
