How do you control for selection bias in first-party polling built on your own auction?
How do you show up accurately in an advertiser's MMM?
Intent-to-treat, ghost ads, or geo testing for your incrementality solution?
What attribution and identity fundamentals do you need for first-party lift?
How do you demonstrate attribution as an OOH platform?
First-party measurement, or third-party partnerships?
Which measurement tools unlock the biggest budgets in Travel, Retail, or Telco?
How do you measure creators and influencers, not just ad placements?

We answer questions like these every day for our clients, which include some of the top ad platforms.

How we help

Where we plug in depends on your platform and priorities. A few of the ways we help, all grounded in science.

Technical design
We build eng-ready PRDs and working prototypes: first-party incrementality systems, measurement APIs, pixels and CAPI, polling solutions, and third-party integrations. All tailored to your platform and priority verticals.
MarSci talent
Top marketing science talent on a fractional or full-time basis. Our founding team are ex-MarSci leaders, and our deep bench of analysts can be your secret weapon to scale client delivery and internal builds.
Custom measurement approaches
Deployments for every platform and inventory source: on- and off-platform, cross-device, creators and influencers, retail media, CTV, and OOH. Many require modeled exposure, multi-hop identity resolution, or special geo-testing considerations. We design a defensible approach and the infrastructure to support it.
Selected work

GBS designed the specs for a CAPI, an event-attribution stack, and a first-party intent-to-treat incrementality methodology, all built to fit seamlessly into the client's complex, multi-ad-server stack. We worked directly with their technology partners and internal teams to keep everything functioning as the business evolved.

What we built
  • CAPI and event-attribution stack specifications
  • A first-party intent-to-treat incrementality methodology
  • Integration across a complex, multi-ad-server stack

We designed a complex attribution system for digital out-of-home, drawing on first- and third-party identity assets, geo-location, and novel bluetooth device-recognition technology. We charted the potential measurement-partner landscape and devised a geo-incrementality approach to demonstrate outcomes lift for performance advertisers.

What we built
  • dOOH attribution across 1P/3P identity, geo, and bluetooth signals
  • A measurement-partner landscape and integration plan
  • A geo-incrementality approach for performance advertisers

GBS operates as an ongoing incrementality partner for a top CTV platform, running bespoke lift tests that specialize in the edge cases measurement SaaS cannot easily cover. We also act as measurement-product advisors, helping navigate strategic challenges in mobile attribution and first-party incrementality.

What we built
  • An ongoing bespoke lift-testing partnership
  • Coverage for edge cases SaaS cannot reach
  • Product advisory on mobile attribution and 1P incrementality

Our team filled marketing-science talent gaps for a global communications platform. We scaled research across brand-measurement vendors, automated the brand-lift testing process, and ran campaign measurement for the client's advertisers.

What we built
  • Fractional marketing-science talent
  • An automated brand-lift testing process
  • Campaign measurement for the platform's advertisers

GBS devised a novel approach to measuring the incrementality of influencer campaigns for a top content-creator platform. We demonstrated statistically significant lift across a range of campaigns, stratified by advertiser type, and designed a framework to accurately model exposure data for export into client MMMs.

What we built
  • A novel influencer-incrementality methodology
  • Statistically significant lift, stratified by advertiser type
  • An exposure-data framework for export to client MMMs
