Your tracking looks fine. Your data isn't.
Fidero fixes your data where it's collected, so every tool you run finally agrees.
- Expert setup, platform-run operations
- Proven improvement before you subscribe
- Your data, your warehouse – zero lock-in
Clean data, or you don't pay.
Used by teams who can't afford to guess
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 sales. Google and Meta only ever saw the form fills. Marketing knows which ads worked – and can't prove it to anyone.
Product
Three profiles, one customer
The same customer shows up as three different people across your site, app and CRM. 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.
What powers your tools?
Your tools don't feed themselves. Whether you can trust what they show depends on the layer underneath them.
Fidero is that layer. It sits between your sources and your tools, and lands every customer event in the right place, in the right format, with the right context attached.

Not the CDP you're picturing
Fidero is a Stateful CDP – a customer data platform with memory. It has no audience builders, journey canvases, campaign tools or dashboards. Its one job is to keep your customer data complete, connected and correct, everywhere it flows. You tell Fidero "Set up a new offline conversion for purchases" and your configuration updates automatically on the server, so nobody on your team needs tag manager expertise. The analytics, ad platforms and warehouse you already run stay where they are and finally agree with each other.
Built for
- Customer journeys spanning sites, checkouts, apps and CRMs
- 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
Fidero works with the tools you already run
Complete data, for every team that runs on it
When a customer journey crosses systems (site to app, or site to the CRM where the sale closes), context gets lost. That one gap breaks attribution, identity and quality at once, and 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 customer, and train models on complete histories. Every identified user is resolved exactly – 100%, never guessed.
For engineering & leadership
Complete Quality
Fidero enforces consent, catches duplicates and monitors delivery to keep it at ≥99.5%. Engineers stop firefighting tracking, 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.

From first look to proven data
We don't ask for belief. Each step proves the next is worth taking.
Data Infrastructure Audit
It costs £250, fully refunded if you don't proceed and credited if you do. Within 48 hours you see the gap behind your #1 pain and what it's costing you.
30-Day Implementation Sprint
Your engineers integrate once, and our tickets and QA guide every step. Fidero goes live alongside your existing stack without interrupting your reporting, and weekly acceptance gates show measurable improvement before we continue.
Clean data, compounding
The subscription starts only once improvement is proven against the target we agreed. After that, the subscription keeps the engine running: adapters absorb API changes, consent stays enforced and quality compounds instead of drifting.
Find out why your numbers don't match
Tell us where it hurts: sales your ad platforms never see, journeys you can't follow, tracking nobody wants to own. The audit shows you the gap behind it, in plain language.
- Focused on the single pain costing you most
- Evidence from your own tools, not guesswork
- A 1–2 page report within 48 hours
