How we help

Three decisions worth getting right.

For growth leaders weighing material investment across channels or markets, especially when the numbers point in different directions.

01 / REACH

Where should we move budget?

Compare investment options against customer value, revenue and the quality of the evidence. Make the commercial trade-off in value, volume and rate: revenue, orders and average order value.

  • Channel and market allocation
  • Scale, fix, test or stop
02 / CONVERT

What’s holding growth back?

Find the constraint before committing more budget. Separate customer volume, value and conversion.

  • Revenue and customer economics
  • Prioritised growth decisions
03 / INVEST

Which results can we trust?

Use attribution, marketing mix modelling and incrementality together where they can support the business decision.

  • Tracking, modelling and testing
  • A proportionate measurement roadmap

From direction to delivery

Set the direction. Build the capability. Embed better decisions.

Work with a senior partner to turn an investment question into a repeatable decision system. Set commercial priorities, evidence standards, roles and routines, then build your team’s capability to use them. Specialist partners can implement technical components, with clear ownership and agreed adoption checks.

What you receive

Build a decision system your team can use.

Get a clear investment recommendation, the evidence and assumptions behind it, and a practical way to act on it. Where the problem calls for it, the work also defines decision rules, evidence standards, roles, review routines, tools and team practice so better decisions continue after the project.

Put your budget where it works harder

Test before you commit more budget.

Start with a small test. Use the results to decide whether to increase investment.

What we’ll check
Will the extra spend bring in customers at a worthwhile return?
What you’ll learn
Whether the results justify a bigger investment.
Your next step
Agree the test budget, who’ll run it and when to review.

Choose where to increase investment, where to cut back and what to test first.

Services

Start with the decision you need to make.

The core engagement builds a better way to make and act on marketing investment decisions. Start with a defined project, use a paid diagnostic when the question is unclear, or add selective advice as the new approach takes hold.

Before we talk

A few practical questions.

Do you build attribution models and MMM yourself?

I define what the measurement needs to answer, shape the brief, select and challenge specialist partners, and connect their work to your investment decisions. Specialist analysts and engineers build the technical models. I lead the initiative, help your team use the outputs and keep delivery moving.

Can you work with our team, agency or measurement provider?

Yes. GV provides independent commercial interpretation across your existing evidence and partners. We agree responsibilities and who owns the final decision at the outset.

What evidence will you need?

It depends on the decision. We agree relevant campaign, revenue, customer-value and measurement inputs before scoping the work, and make gaps and limitations explicit. Not every project needs attribution, MMM and an experiment.

What will we receive?

A concise decision deck, supporting analysis and explicit assumptions, plus an action plan with owners, timing and review measures. Where the project needs a repeatable process, we also define decision rules, evidence standards, roles, routines, tools and team practice. Examples include budget options, a revenue decision tree or a measurement roadmap.

Who leads delivery and who builds the technical components?

David leads the commercial strategy, decision-system design and team adoption. Your team, agency or agreed specialist partners build specialist technical components where needed. We agree ownership, milestones, practice, handover and adoption checks upfront.

What happens on the free introductory call?

We discuss the decision, business outcome, sponsor and timing to establish fit and scope. It’s an introductory conversation. We agree the scope and fee for any diagnostic or project separately.

Let’s talk

What decision do you need to make?

Tell us the business outcome, when you need to decide and what’s making the choice difficult. We’ll establish whether GV can help.

Useful context: the investment at stake, your decision date, who owns the decision and the evidence you already have.
