Google Marketing Platform.
Server-side tracking.
Growth infrastructure that actually measures.

We don't guess what's working - we engineer the measurement layer that tells you, we run the media on top of it, and where the system does not exist yet, we build the software too. Server-side GTM, Meta CAPI, Enhanced Conversions and DV360 programmatic on one side; paid media strategy and custom platform builds on the other. From a tracking audit to a product in production.

Systems we built and still run.

Measurement work put us inside the tools, and the tools were not good enough, so we started building our own. These are not client brochures - they are software we designed, wrote, deployed and operate. The same team builds platforms for clients from scratch.

OUR OWN PRODUCT / SAAS

Tragly

Our managed server-side tagging platform. Multi-tenant Google Tag Manager server containers, with onboarding that scans a site, provisions GA4, Meta CAPI and Microsoft UET, verifies the install and rolls back cleanly if something breaks. We do not just configure measurement infrastructure - we wrote the platform that deploys it.

BUILT & OPERATED BY US
AUTOMOTIVE / FULL PLATFORM BUILD

MegaEV

A complete platform for an independent Tesla repair specialist in Surrey, built from scratch: a static site with its own build pipeline, a PHP enquiry and vehicle-lookup API, an admin area, a Markdown-driven workshop diary, self-hosted fonts so no page calls a third party, structured data for local search, and an llms.txt for AI assistants - because that is where the customers actually come from.

PHARMA / COMPLIANCE INFRASTRUCTURE

ClinicMeta

A compliance operating system for clinical trial disclosure. Not a service provider - an autonomous infrastructure where compliance is the default state and a missed disclosure is surfaced before a deadline passes.

Request an Audit

Tell us what you are currently tracking and where the numbers do not reconcile. We reply within two working days.

What the first review includes

A free, no-obligation review of your current setup: your tag container, your GA4 configuration, and how your conversion numbers compare across platforms. You get a written summary of what is broken, what it is likely costing you, and the shortest path to fixing it. If a full audit or a build is the right next step, we quote a fixed price before any work starts.

The age of guessing is over.

For decades, growth was a gamble dressed up in strategy decks. Throw money at channels. Hope the funnel holds. Celebrate the wins. Bury the waste.

We rejected that model. Trendfingers exists because growth should be engineered, not hoped for.

Built by operators, not theorists.
