Data you can finally trust
Complete, trustworthy data infrastructure across attribution, identity and quality - without tag manager expertise.
Marketing: Recover 20-40% of dark conversions · Product: Track complete user journeys across domains · Engineering: Eliminate tracking maintenance burden
£250 - fully refundable & credited to implementation
Campaign context preserved everywhere
We capture click IDs before they're lost, preserve them through redirects and domain changes, and enrich server events automatically with first/last touch attribution.
Target: ≥85% of conversions have attribution context
Typical proof: 20-40% conversion recovery for personal/lifestyle subscription companies
User journeys unified across experiences
We track the same person across your marketing site, checkout and app - even when they don't log in. When they finally create an account, we automatically connect all their anonymous behaviour to their profile.
Target: ≥90% cross-domain session linking
Outcome: Product teams track complete activation→retention funnels
Accurate, compliant data delivered automatically
One lightweight SDK replaces tag soup. Configuration updates automatically server-side. When Meta updates their API, changes deploy automatically - zero action from your team.
Targets: 95% consent enforcement · 98% deduplication · 99% delivery
Outcome: Engineering ships features, not tracking fixes
"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." Dylan Bourguignon - Founder at SO-SURE
Finally prove which campaigns drive revenue
Customer clicks your Meta ad, signs up, subscribes - shows as "Direct" in GA4. £50 spent, can't prove it worked. This is the frustrating part: happens on 30%+ of your conversions.
Attribution context stays intact from first ad click through sign-up and subscription. Meta match rates improve because we're sending from both browser and server - two chances to match, counted once.
Scale spend knowing which campaigns actually drive subscription revenue - whether conversions happen in-browser or server-side.
See the complete story, not fragments
Connect pre-signup behaviour to post-subscription activation. Link marketing source to feature adoption. Understand why users from Google convert differently than Meta users - because you can finally track the complete journey.
Your power users who came from that specific TikTok campaign? You'll know. Which acquisition sources drive best retention? Finally visible. Product decisions on complete data, not fragmented guesses.
One SDK to replace them all
Replace the tag soup with a single, governed SDK. No more "can you add this script?" requests. No more debugging why GTM fired twice. No more emergency calls when Meta updates their API.
Data teams get clean training data from day one - churn prediction models with complete attribution context, LTV forecasts with full user journey history. Your ML models are only as good as your training data.
We don't ask for belief - we prove it. Our Data Infrastructure Audit shows you exactly where you're losing data completeness across attribution, identity and quality - and what recovering it is worth. Zero-code. 48-hour turnaround.
