Real Results From Real Data Projects

Every project below started the same way — a company that knew their data wasn't right but couldn't pinpoint why. We fixed the foundation, and the results followed.

E-Commerce

Server-Side Tracking Recovery

Challenge

A mid-size e-commerce brand was losing 35–40% of conversion data after iOS 14.5 and cookie consent changes. Facebook ROAS reporting was unreliable, and Google Analytics showed 30% fewer transactions than their payment processor.

Solution

Deployed a full server-side tracking stack using GTM Server-Side on Google Cloud Platform. Implemented Conversions API for Meta, enhanced conversions for Google Ads, and built a first-party data pipeline.

SaaS B2B

GA4 Migration & Full-Funnel Analytics

Challenge

A B2B SaaS company with 200K+ monthly visitors was still running Universal Analytics alongside a broken GA4 setup. Marketing couldn't attribute pipeline revenue to specific campaigns.

Solution

Designed a measurement plan mapping business KPIs to GA4 events. Implemented cross-domain tracking and built a custom BigQuery pipeline connecting GA4 with HubSpot.

Retail

Analytics Audit & Data Quality Overhaul

Challenge

An omnichannel retailer had analytics that "kind of worked" — duplicate transactions, bot traffic inflation, and Google Ads conversions that didn't match the backend. Six-figure ad spend decisions were based on flawed data.

Solution

Conducted a full-stack analytics audit covering GTM containers, GA4, Google Ads conversion tracking, and third-party scripts. Identified 23 issues and rebuilt GTM from scratch.

EdTech

Consent Mode & Privacy-First Measurement

Challenge

An EdTech platform operating across the EU needed GDPR compliance while maintaining meaningful analytics. Consent rates were below 40% — over half of traffic was invisible to Google Analytics.

Solution

Implemented Google Consent Mode v2 with Advanced mode. Optimized consent banner UX and deployed server-side tagging for maximum accuracy.

DTC Brand

BI Dashboards & Data Visualization

Challenge

A DTC brand was drowning in data but starving for insights. Team spent 15+ hours weekly pulling reports manually. Each platform told a different story, and nobody trusted the numbers.

Solution

Built a centralized data warehouse in BigQuery connecting GA4, Shopify, Meta, Google Ads, and email marketing. Created automated Looker Studio dashboards with a single source of truth.

How are you different from a full-service agency that also offers analytics?

We are not a full-service agency. We are technical analytics specialists. Many agencies treat analytics as a 'value-add'.
For us, it's our entire business.
They build dashboards; we build the entire data stack (server-side GTM, warehousing, activation). We are the experts they hire when the data gets too complex and critical to get wrong.

How will you work with our existing marketing and data/engineering teams?

What tools and platforms do you specialize in?

Do you only work on long-term retainers?
