The NBT Growth Model: How to Build a Repeatable Growth System

Growth doesn't become predictable simply because a company runs more campaigns, hires more people or invests in better tools.

A business can have a strong product, an active marketing team and a growing sales pipeline, yet still struggle to turn activity into sustainable revenue.

Often, the missing element is not another marketing channel. It's a system that connects strategy, execution and learning.

At NBT, we use the NBT Growth Model, a four-stage methodology designed to help businesses identify growth constraints, choose the right priorities, coordinate execution and continuously improve results.

The four stages are: Growth Marketing Checkup, Growth Route Formulation, Growth Navigation and OKR-Driven Optimisation.

They form a continuous cycle rather than a one-time planning exercise.

The Four Stages of the NBT Growth Model

1. Growth Marketing Checkup: Diagnose Before You Invest

When growth slows, businesses often respond by increasing activity.

More advertising. More content. More outbound sales. More tools.

But increasing activity before understanding the underlying problem can amplify inefficiencies.

The Growth Marketing Checkup examines the business's ability to grow, starting with its customers, market position, existing assets and commercial processes.

NBT's methodology considers five dimensions:

• Product maturity and traction: Is the offering ready to scale, and is there evidence of customer demand?

• Revenue consistency and growth goals: Does the business understand its commercial baseline and objectives?

• Asset readiness: Are the website, messaging, content, CRM and conversion assets ready to support growth?

• Activity readiness: Which acquisition, conversion and retention activities are working?

• Execution ownership: Are responsibilities and decision-making clearly assigned?

The purpose is not to produce a lengthy audit. It is to identify the constraints that deserve attention first.

For example, poor lead generation may appear to be an advertising problem when the underlying issue is unclear positioning, weak conversion assets or incomplete lead tracking.

The principle: Diagnose the system before optimising individual activities.

2. Growth Route Formulation: Decide Where Growth Will Come From

Once the constraints are understood, the next question is strategic.

Where should the business focus its resources?

Growth Route Formulation connects customer understanding with the choices that determine how a company will acquire, convert and retain customers.

Depending on the business, this may include:

1. Defining or refining the ideal customer profile

2. Prioritising customer segments and markets

3. Clarifying positioning and value propositions

4. Selecting the most appropriate acquisition channels

5. Mapping conversion journeys and commercial handovers

6. Establishing growth hypotheses, objectives and success measures

A strong growth route is not a list of everything the company could do.

It is a set of choices about what matters most, what to test and what to postpone.

A useful way to translate strategy into execution is to define a specific growth hypothesis around one offering, one target market, one customer persona and one channel.

For instance, instead of broadly deciding to “invest in paid acquisition,” a team might test whether a particular service proposition attracts qualified buyers in one geographical market through Google Search.

That makes the hypothesis measurable and the learning actionable.

The principle: Focus creates better experiments and clearer decisions.

3. Growth Navigation: Connect the Activities That Drive Revenue

Even a strong strategy can fail when execution is fragmented.

Marketing creates campaigns without sufficient sales input. Sales teams receive leads without the right context. CRM data is incomplete. Content supports visibility but not conversion.

Growth Navigation connects the capabilities required to execute the chosen growth route.

NBT's methodology brings together six areas of execution:

Not every business needs all six capabilities equally.

A company entering a new market may prioritise positioning, demand generation and sales enablement. A more mature business may need to improve conversion, CRM integration and customer retention.

What matters is that activities contribute to shared growth objectives.

What this looks like in practice

In an NBT engagement with an enterprise B2B technology platform, reported results over six months included:

• 102% increase in qualified inbound leads

• 68% improvement in website conversion rate

• 38% increase in lead-to-opportunity conversion

The work combined organic, paid, email and content activities into a more connected demand-generation system.

The takeaway isn't that every business can achieve the same percentages.

It's that growth performance should be evaluated across the customer journey, not solely by the results of individual channels.

The principle: Growth activities are more effective when they operate as a connected system.

4. OKR-Driven Optimisation: Turn Activity Into Learning

Launching campaigns is not the end of execution.

A growth system must continuously assess whether its assumptions were correct and whether resources are being used effectively.

NBT uses objectives and key results to connect growth priorities with measurable outcomes.

A typical operating rhythm includes:

Weekly reviews: Evaluate activities and experiments, identify blockers and make immediate adjustments.

Monthly reviews: Assess progress against agreed objectives, examine the reasons behind results and adjust priorities.

Quarterly planning: Use accumulated learning to revisit the growth route and define the next cycle.

For individual experiments, the decision process is straightforward:

Define → Launch → Review → Scale, Iterate or Stop

A campaign that produces little learning is not automatically a good use of resources simply because it generates activity.

Likewise, a test that fails to meet its target can still be valuable if it provides reliable evidence about customer behaviour or channel suitability.

What measurable optimisation can achieve

NBT's client work provides additional examples of reported growth outcomes.

Multi-region enterprise technology GTM

• Marketing-qualified leads increased 57% compared with prior launch averages.

• Conversion to sales-accepted leads increased 42%.

• Average campaign click-through rate increased 68%.

US-focused business expansion

• Qualified inbound leads increased 3.4× over nine months.

• Cost per qualified lead decreased 31%.

• Marketing-influenced revenue contribution increased 2.8× year on year.

These outcomes came from distinct client engagements. They are not guaranteed results of applying the Growth Model, and the available case-study summaries do not isolate the contribution of each individual activity.

They do, however, illustrate the types of commercial outcomes NBT measures when working across growth strategy and execution.

The principle: Measure progress against commercial outcomes, then use what you learn to improve the next decision.

Why the Model Is a Loop, Not a Funnel

A traditional growth plan can become outdated soon after execution begins.

Customers change. Competitors reposition. Acquisition costs move. Channels become less effective. New opportunities appear.

A repeatable growth system must respond to that evidence.

The NBT Growth Model therefore works as a continuous loop:

Checkup → Formulation → Navigation → Optimisation → Checkup

The fourth stage informs the next first stage.

That does not mean repeating a full strategic audit every month. It means regularly challenging assumptions and reassessing constraints when new evidence justifies doing so.

Assess Your Own Growth System

Before investing in additional growth activities, ask these six questions.

If several answers are unclear, additional spending may not be the best immediate move.

Start by identifying which part of the growth system needs attention.

Building Growth as a Repeatable Capability

The NBT Growth Model is built around a simple idea:

Sustainable growth comes from making better, connected decisions repeatedly.

Diagnosis identifies what matters.

Strategy determines where to focus.

Execution turns those choices into coordinated activity.

Optimisation converts results into learning.

Together, these four stages provide a practical structure for moving beyond isolated campaigns and towards a more systematic approach to growth.

The starting point is not asking, “What marketing activity should we launch next?”

It's asking:

“What is preventing us from achieving our next growth objective, and what evidence would help us decide what to do about it?”
