Statistical significance

Determine whether experiment results reflect real differences or random chance to avoid making expensive decisions based on noise instead of signal.

Growth orchestration

The cockpit that sits above your four growth engines. Individual teams can excel at their own metrics, but without orchestration they're musicians playing different songs. This is where everything comes together and where improvements in one engine amplify gains in another.

Growth team tools

Growth team tools

The wrong tools create friction. The right ones multiply your output without adding complexity. These are the tools I recommend for growth teams that move fast.

Compound growth

Compound growth

Small improvements multiply. A 10% gain across twelve metrics doesn't add up to 120% - it compounds to 3x growth. This is the mathematical engine behind systematic growth.

Growth strategy

Growth strategy

Four decisions that shape everything else. When growth feels harder than it should, the problem is usually here. Get these right and execution becomes much easier.

Growth rhythms

Growth rhythms

Without rhythm, effort becomes scattered and progress invisible. A consistent operating cadence keeps your team aligned and your growth system continuously improving.

Creating strong hypotheses

Most experiments fail before they start because the hypothesis is vague or untestable. Learn how to write hypotheses that are specific enough to prove or disprove and tied to metrics that matter.

Analysing and acting on results

Statistical significance is just the beginning. Learn how to interpret results correctly, avoid false positives, and turn winning experiments into permanent improvements across your growth engines.

Wiki

Total Addressable Market (TAM)

Estimate the maximum revenue opportunity if you captured 100% market share to size your opportunity and prioritise which markets to enter first.

Contact management

Organise customer and prospect information to track relationships, communication history, and next steps without losing context or duplicating effort.

Pareto Principle

Focus effort on the 20% of activities that drive 80% of results, systematically eliminating low-yield work to maximise output per hour invested.

Standard Operating Procedure (SOP)

Document your repeatable processes in clear, step-by-step instructions that ensure consistency, enable delegation, and capture institutional knowledge.

Hypothesis testing

Structure experiments around clear predictions to focus efforts on learning rather than random changes and make results easier to interpret afterward.

Objectives and Key Results (OKRs)

Set ambitious goals and measurable outcomes that cascade through your organisation, creating alignment and accountability for strategic priorities.

Competitive advantage

Identify what you do better or differently that competitors can't easily copy to defend margins and win customers consistently over time.

Annual Recurring Revenue (ARR)

Track predictable yearly revenue from subscriptions to measure business scale and growth trajectory in B2B SaaS and recurring revenue models.

Multi-touch attribution

Distribute conversion credit across multiple touchpoints to recognise that customer journeys involve many interactions and channels working together.

A/B testing

Compare two versions of a page, email, or feature to determine which performs better using statistical methods that isolate the impact of specific changes.

Minimum viable test

Design experiments that answer specific questions with minimum time and resources to maximise learning velocity without over-investing in unproven ideas.

Growth lever

Focus resources on high-impact business mechanisms where small improvements generate disproportionate results across the entire customer journey.

Churn rate

Measure the percentage of customers who stop paying to identify retention problems and calculate the true cost of growth in subscription businesses.

OMTM (One Metric That Matters)

Focus your entire organisation on the single metric that best predicts success at your current growth stage, avoiding distraction and misalignment.

Pipeline coverage

Calculate how much pipeline you need relative to quota to ensure you generate enough opportunities to hit revenue targets despite normal conversion rates.

Sales-led growth

Win customers through direct sales conversations where reps guide prospects from discovery to close with personalised solutions and relationship building.

Referral marketing

Turn satisfied customers into active promoters who systematically bring qualified prospects into your pipeline at near-zero acquisition cost.

Positioning statement

Define how you're different from alternatives in a way that matters to customers to guide all messaging and ensure consistent market perception.

Deal stage

Define pipeline progression steps to standardise how reps advance opportunities and give managers visibility into where deals stall or convert unexpectedly.

Last-touch attribution

Assign full conversion credit to the final touchpoint before purchase to identify which channels close deals but miss earlier influences that started journeys.
