measurement.

Your business is unique. Your marketing strategy is unique. So why are you using generic, off-the-shelf measurement tools?

Measurement is a strategic moat. Not a cost-center.

But that is only true if you own it. Black-boxed, off-the-shelf solutions are rigid, and they leave you beholden to a third party.

Building an in-house program is hard and multi-faceted. The top growth marketers all own their measurement. But it took them years and millions of dollars to get there.

GBS accelerates that, applying the principles of science, deep experience, and AI-powered tooling.

How we work
01

We become experts in your business.

Our team runs an intensive onsite with yours, learning every nuance needed to build a measurement program.

02

We analyze your org, stack, and data.

With deep context from the onsite, we recommend upgrades, tests, and analytical approaches grounded in hard data, so the roadmap is bespoke to your business.

03

We perform bespoke analytics.

We run tests, build MMMs and causal analyses, deploy custom AI agents, and more. Whatever it takes to answer your business questions and own your measurement.

04

We educate executives and operators.

We are honest, but never dogmatic. An in-house program lives or dies by intangibles: culture, willingness to experiment, and leadership engagement.

05

We deploy your in-house roadmap.

Fully bespoke and ready to build. Take the roadmap and run, have us act as PMs alongside your developers, or have us build the systems outright. Your call.

We are not on a soapbox delivering a deck.

We get our hands dirty and build, for you and with you. Full transparency and auditability, with all model and system code, designs, and data handed directly to you.

Selected work

Over a year, we moved a premier consumer-fintech brand off multiple measurement-SaaS vendors and onto a fully in-house program. We worked with the executive team to underscore incrementality, then structured a series of tests and custom MMMs to surface immediate efficiency gains.

From there we expanded the models to new markets and subsidiaries, helped interview a new Marketing Science leader, and delivered a prototype in-house system for always-on incrementality, implemented by the client's own engineers.

Outcomes
  • 15%+ growth-efficiency gains
  • Millions in marketing spend saved
  • Hundreds of thousands in SaaS costs eliminated

We guided a top multinational sportsbook, casino, and gaming company through in-housing its measurement, starting with a detailed technical and strategic audit of their international growth stack, talent, org design, and approach. The audit surfaced crucial data and technology gaps.

We recommended an incrementality-focused strategy with aligned OKRs, designed a new org structure with key leadership roles and helped interview for them, spec'd several key tests, and built a custom market-share simulator showing how measurement accuracy could win a critical new market. We closed with a full roadmap of systems, methods, and org.

Outcomes
  • $48M+ inefficient spend eliminated
  • A pLTV fix ended 2× under-spend in critical geos
  • Full reorg completed, with key leadership hired

We transitioned a highly funded international consumer-healthcare-hardware company from outsourced attribution SaaS to an in-house, incrementality-focused engine, helping the team escape three-times-a-week growth meetings and dozens of granular OKRs in favor of a few incrementality-based goals.

We provided months of fractional, hands-on data-science staffing, deployed several custom incrementality tests, built a geo-hierarchical MMM, and shipped a bespoke growth-analytics agent trained on the customer's own data.

Outcomes
  • A key channel was 40% over-reported by the SaaS vendor
  • Significant CTV inefficiencies uncovered
  • A crucial overlooked channel identified
  • Hundreds of thousands in SaaS fees eliminated

We upleveled the internal measurement team of a top US sportsbook, gaming, and casino platform bringing measurement fully in-house. We rebuilt their MMM suite from the ground up, accounting for significant regional skews and multiple brands and verticals interacting with one another, and separated acquisition from upsell and retention effects.

Our custom hierarchical Bayesian MMMs were calibrated with complex incrementality tests designed to minimize opportunity cost while answering key business questions. The client deployed the models at scale and iterated on them independently.

Outcomes
  • Acquisition found to be 2× as incremental as believed
  • Another strategy shown to drive ongoing monetization
  • Budget-neutral optimization revealed 1.5× ROI

We enabled an international ecommerce and apparel company to retire a high six-figure-per-year measurement-SaaS contract and bring modeling and testing in-house. We designed a series of crucial tests the SaaS provider had never run, answering key business questions and uncovering the true incrementality of their spend.

Those tests powered a fully bespoke MMM, with all code handed to the client, who scaled it to other internal brands and took over running the model themselves.

Outcomes
  • $30M+ GMV improvement identified through optimal spend and allocation
  • Hundreds of thousands in SaaS costs saved
