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
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. 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.Want to understand the technical details? See Server-first

State Capture, identity resolution and consent enforcement work together.
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.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.
