A bit of a background
We've got 7+ years of web-measurement experience under the hood.
Our story spans from the trenches of Google's customer support centre, where we understood how under-estimated web measurement is among SMBs.
One day we decided to leave the corporate boat and fix this.
We specialize in:
End-to-end analytics — we set up a tracking infrastructure that lets you analyze every customer touchpoint on the journey to conversion. We bring together user behaviour, ad spend and completed purchases with offline sales and micro-conversions (phone calls, newsletters) in a single system. That lets us evaluate every marketing channel with attribution models, and make decisions from complete data.
Step-by-step, smoothly…
Audit
We do your website and marketing channels due diligence, and collate it with your business objectives.
Scope definition
Project implementation plan broken into checklists, time estimates and task ownership. Expectations are important.
Documentation
Your developers will be delighted with the instructions. We also know how to properly communicate with those aliens.
End-to-end measurement
From the first visit on the website to offline behaviour, ad spend and completed purchases — in a single system.
Yummy visualizations
Be it a complex marketing funnel, lead scoring, a ROAS report or seemingly unrelated data — we'll make sense of it.
ML and CRO
Yes, sometimes your website sucks. We're the ones who will tell you the truth and fix things for the better.
Some beauty

The people who'll actually do the work
A small, senior crew — no account managers, no handoffs to juniors. You talk to the engineers who build your tracking.
Denis
8+ years in analytics and performance marketing. Cut his teeth inside Google's support centre, then left to fix the measurement gap SMBs live with.

Yaroslav
GTM, BigQuery and Looker wizard. Python and SQL are his second language. Turns messy tracking into clean, queryable data.
Nick
JavaScript developer and technical creative. Owns the hard front-end and tag-plumbing problems the API can't reach.
Oleg
Makes campaign performance a breeze. “ROAS” is his mantra — and the reason clean measurement matters to him.
The questions everyone asks first
Consent + tracking fixes typically run €250–500 as a one-off on WordPress or Shopify. Full tracking setups start around $1,000 and advanced end-to-end implementations $2,000+. Server-side GTM and Google Ads management run on monthly retainers. We scope every project up front with an estimate per action item — no surprises.
If your consent layer is misconfigured, Google receives fewer conversions than actually happened, and Smart Bidding optimises on incomplete data. Consent Mode v2 lets Google model the gap so your bidding sees the full picture — and keeps you compliant with UK/EU rules now that DUAA has raised cookie fines to £17.5m or 4% of turnover.
A correct fix usually reduces measured traffic and conversions by 15–40% — because you were counting data you legally shouldn't have. We set that expectation before we touch anything, then recover the signal with Consent Mode modelling and, later, server-side GTM. Honest measurement beats flattering measurement.
A small, senior team led by Denis — ex-Google, 8+ years in analytics and performance marketing — plus specialist data engineers and PPC pros. We stay small on purpose: we own what we ship and treat your business strategically, not as a ticket queue.
