Our core promise is trust in your data. Our position as the Server-First CDP is the architectural foundation that makes this promise a reality.
This isn’t just a feature; it’s the design philosophy that guarantees complete data infrastructure across attribution, identity and quality.

How it works
What this means for you
Imagine never having to explain why GA4 shows 1,000 conversions whilst Meta claims 600 and Google Ads reports 750. With server-first architecture, your tools finally tell the same story because they’re working from the same trusted source of truth.The problems it solves:Multi-team trust issues ripple across your organisation when data is incomplete. Marketing can’t prove ROI when 30%+ of conversions show as “direct”. Product can’t track complete journeys when user identity fragments across domains. Engineering waste time maintaining brittle tracking scripts. Legal face compliance risks when consent enforcement is inconsistent. Leadership make six-figure decisions on data they don’t actually trust.The outcomes you’ll achieve:Complete data infrastructure means every team gets trustworthy data. Marketing sees 20-40% conversion recovery with GA4↔Meta↔Ads convergence. Product tracks complete user journeys from anonymous visitor through retention. Engineering dramatically reduces tracking maintenance with one governed SDK. Legal gets automatic compliance with 95%+ consent enforcement from day one. Leadership sees a single source of truth across all reporting.Timeline: Most B2C subscription companies see their tools showing consistent numbers within 24-48 hours. Within a week, recovered conversions become visible. Within 30 days, most teams hit target metrics across all three dimensions.What is a Server-First CDP?
Server-First CDP means the server does the heavy lifting. All data processing, identity resolution, enrichment and consent enforcement happen server-side in a controlled, unified environment.A lightweight client-side pixel captures raw signals and critical browser state, but its behaviour is governed by a single, server-side configuration. The server acts as the single source of truth for all your data governance and integration logic.This contrasts with client-first CDPs, where the in-browser SDK acts as the primary hub for data processing. That approach is vulnerable to browser limitations (like ITP), ad blockers and network issues – leading to data that’s less resilient and harder to govern universally.The architectural difference
Traditional CDPs (client-first):Heavy browser SDKs process data. You configure how data flows: edit templates, publish containers, wire integrations, write custom Functions for enrichment. When platforms update their APIs, you manually accept template changes and republish. Configuration expertise is required, not optional.Fidero (server-first):Lightweight pixel captures raw signals. You configure what outcomes you want: “Enable Google Ads enhanced conversions” – done. Configuration updates automatically server-side, changes propagate to your SDK. When Google updates their API, the adapter updates server-side automatically. Your tracking keeps working. Zero expertise required.The difference isn’t features – it’s fundamental design philosophy.[Diagram: An architecture comparison showing two approaches side-by-side. Left side: ‘Client-First CDP’ with a heavy browser SDK processing data and sending to multiple destinations, with configuration burden shown. Right side: ‘Server-First CDP (Fidero)’ with a lightweight pixel sending raw data to a central server, which then processes and routes to all destinations with zero configuration burden. Emphasise the server as the single source of truth.]How server-first delivers attribution, identity and quality
Our server-first architecture is the foundation that makes this possible:
Complete Attribution: The pixel captures click IDs before browsers drop them. The server persists attribution context. When a purchase event arrives days later via webhook, it’s automatically enriched with original campaign context. Result: 85%+ attribution coverage, 20-40% conversion recovery.
Complete Identity: The server maintains unified user profiles across domains and devices. Anonymous browsing → signup → app conversion all merge into a single chronological journey automatically. Result: 90%+ cross-domain session linking.
Complete Quality: The server enforces consent, prevents duplicates and confirms delivery – all handled automatically before data reaches any destination. Result: 95% consent, 98% deduplication, 99% delivery – zero ongoing maintenance.
Zero-config outcomes
You tell Fidero what outcome you need, and your configuration updates automatically on the server.
Want Meta CAPI with enhanced matching? You tell Fidero what you need – that’s it. No templates to configure, no containers to publish. Your configuration updates server-side automatically within 24 hours. Data starts flowing immediately.
When Meta updates their API weeks later? The adapter updates server-side automatically. Your configuration keeps working without any action from your team.
What this means: You specify outcomes, not implementation steps. No tag manager expertise required.
Average time per integration: 5 minutes to request, 24 hours to activate.
Compare to GTM/Segment: 4-6 hours learning platform internals, configuring
templates, mapping parameters, publishing containers – then doing it again
every time APIs update. The server handles the complexity whilst you focus on
outcomes.
Why server-first matters
Completeness: Minimal client-side logic creates a robust data pipeline less susceptible to browser limitations and signal loss.
Consistency: With the server as the single source of truth, every tool receives the same, consistently enriched data. Your GA4, Meta and product analytics finally tell the same story.
Compliance: Governance and consent are enforced universally on the server before any data reaches a destination – providing effortless compliance.
Governance: Zero-config architecture with automatic updates means your tracking keeps working whilst your team ships product features.
Our server-first architecture is how we deliver on our core promise: data you can finally trust.
