THE PROBLEM / NOTHING ERRORS

Silent failure looks like success

Every tool tells a different story. Engineering says it's working. Everyone else knows it isn't.

Marketing

Right ads, no proof

The campaigns drove real subscribers. GA4 calls them "Direct". Marketing knows which ads worked – and can't prove it to anyone.

Product

Three profiles, one customer

The same subscriber shows up as three different people across your site, checkout and app. No one can say which funnel actually converts.

Engineering

Built right, blamed anyway

Tracking went in exactly as the guides said. Events flow, nothing errors – and the complaints still land on engineering's desk.

HOW IT WORKS / THE INVISIBLE LAYER

What powers your tools?

Your stack has a layer most teams never see. It decides whether anything downstream can be trusted.

GA4 shows your traffic. Meta needs your conversions. Your warehouse stores everything. None of these tools feed themselves – something has to make sure the data going into them is complete, connected and correct.

For most teams, that something is a person: whoever set the tracking up, plus everyone who has patched it since. Manual upkeep drifts – quietly, and usually in the direction of the problems above. Infrastructure doesn't.

Fidero is that layer. It sits between your sources and your tools, gets told what happens (your customer events) and lands every one of them in the right place, in the right format, with the right context attached.

WHAT FIDERO IS / AND WHAT IT ISN'T

Not the CDP you're picturing

Fidero is a Stateful CDP – a customer data platform with memory. No audience builders, no journey canvases, no campaign tools. It does one job: keep your customer data complete, connected and correct, everywhere it flows.

The root cause it fixes is structural. When a customer journey crosses domains and systems (site to checkout to app to backend), context gets lost in the handoffs, and that one gap breaks attribution, identity and quality at the same time. Fidero captures context once and keeps every event whole, so all three stay intact.

It replaces the need for tag manager expertise entirely. And it enhances the analytics and BI you already run rather than replacing them – your tools stay, they just finally agree with each other.

ZERO-CONFIG / CORRECT BY DEFAULT

You specify outcomes. Configuration handles itself.

Every other platform makes you configure how data flows – templates, variables, per-event mappings, hashing rules. Each manual step is a place to get it silently wrong. That's why we didn't simplify configuration – we eliminated it. Best-practice mappings, formatting and deduplication are baked into the platform itself: correctness lives in the product, not in configuration.

You tell Fidero "Set up a new offline conversion for purchases" and your configuration updates automatically on the server. Nothing to deploy, nothing to republish. Stay focused on building.

No configuration expertise required
No containers to publish or templates to maintain
No emergency calls when destination APIs change

Outcomes, not configuration

TRADITIONAL APPROACH

Configure tag manager → map variables → hash PII → wire consent → debug mismatches → republish → repeat for every platform.

Every step needs platform expertise. Every step can fail silently.

FIDERO APPROACH

Send trial_started events to Meta as Purchase.

Mappings, hashing and deduplication activate automatically – and when Meta changes their API, we publish the adapter update. Zero action from your team.

And Fidero remembers

Correct delivery is half the job. The other half is what most platforms can't do: remember. The moment someone first lands on your site, Fidero captures what the browser knows – which campaign, which click, who this is – and keeps it safe on the server.

When that person converts days later through a webhook, a renewal or your backend, Fidero attaches the original context automatically. Server events stop arriving hollow, and your numbers finally reconcile.

Fidero delivers to the tools you already run

FOR EVERY TEAM / THREE DIMENSIONS

Complete data, for every team that runs on it

One infrastructure gap shows up as three different problems. Fixing it at the source fixes all three.

For marketing

Complete Attribution

Campaign context follows the customer everywhere – through redirects, checkouts and conversions that finish server-side. Recover dark conversions and scale spend with confidence.

For product & data

Complete Identity

One person, one profile – across domains, devices and sessions. Follow journeys from anonymous visitor to retained subscriber, and train models on complete histories. Every identified user is resolved exactly – 100%, never guessed.

For engineering & leadership

Complete Quality

Every event accurate, delivered and compliant – consent enforced, duplicates caught, delivery monitored to ≥99.5%. Engineers reclaim the hours tracking used to eat, and leadership gets one source of truth.

We increased the amount of conversion data sent to Google by about 65%. That's when Google's algorithm really started working.

Edward Legge

Head of Digital Marketing, Magnitude Finance

Thanks to Fidero we've got a trustworthy pipeline. Like, the data we get is good. Our data goes reliably into BigQuery.

FIT / NOT FOR EVERYONE

Built for teams building infrastructure

Fidero is a deliberate choice.

Built for

Customer journeys spanning sites, checkouts, apps and backends
Warehouse investment made or planned
Correct data as an outcome, not another stack to build and maintain

Not right for

Quick campaign fixes
Teams set on building and running tracking in-house
Choosing a data platform on price alone

TRUSTED RESULTS / IN THEIR WORDS

What our customers discovered

Having tried multiple solutions, we finally found one that truly works with Fidero. It's simplified our tracking setup, significantly improved our paid campaign performance and allows us to answer questions previously out of reach.

Joel Freeman

Co-Founder at Heights

We struggled with the complexities of tracking conversions across multiple ad networks. Fidero seamlessly integrates with them all and honestly I can't imagine running our campaigns without it.

Xander Gilbert

Founder at Mojo

Fidero has revolutionised our conversion tracking, leading to significant improvements in our CAC/ROAS – it's become an indispensable tool for our business.

THE PATH / AUDIT → SPRINT → LIVE

From first look to proven data

We don't ask for belief. Each step proves the next is worth taking.

Days 1–2

Data Infrastructure Audit

£250 – fully refunded if you don't proceed, credited if you do. Within 48 hours you get a 1–2 page report showing the gap behind your #1 pain and what it's costing you, with evidence from your own tools.

Weeks 1–4

30-Day Implementation Sprint

The work is scoped from the audit. Your engineers integrate once, guided by our tickets and QA, and your infrastructure goes live alongside your existing stack, with your dashboards and reporting uninterrupted. Weekly acceptance gates show measurable improvement before we continue.

Day 30+

Clean data, compounding

The subscription starts only once improvement is proven against the target we agreed – and it's what keeps the engine running afterwards. Adapters absorb API changes, consent stays enforced, and quality compounds instead of drifting.

Your data streams to your tools and your warehouse throughout. You own everything – if you ever stop, nothing is taken away.
