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

Deal stage

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

Referral marketing

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

Product-market fit

Achieve the state where your product solves a genuine, urgent problem for a defined market that's willing to pay and actively pulling your solution in.

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.

Sample size

Calculate how many users you need in experiments to detect meaningful differences and avoid declaring winners prematurely based on insufficient data.

Monthly Recurring Revenue (MRR)

Track predictable monthly subscription revenue to monitor short-term growth trends and make faster decisions than waiting for annual revenue reports.

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.

Email sequence

Automate multi-touch email campaigns that adapt based on recipient behaviour to nurture leads consistently without manual follow-up from reps or marketers.

Annual Recurring Revenue (ARR)

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

Growth hacking

Deploy fast, low-cost experiments to discover scalable acquisition and retention tactics, learning through iteration rather than big bets.

P-value

Interpret experiment results to understand the probability that observed differences occurred by chance rather than because your changes actually work.

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.

Statistical significance

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

Eisenhower Matrix

Prioritise tasks systematically by sorting them into urgent-important quadrants, focusing effort on high-impact activities.

Multi-touch attribution

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

Growth lever

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

Deep Work

Block extended time for cognitively demanding tasks requiring sustained focus, maximising valuable output whilst minimising shallow distractions.

Sales qualified lead velocity

Track how fast your pipeline of ready-to-buy leads grows to forecast sales capacity needs and spot when lead quality or sales efficiency changes.

Prioritisation

Systematically rank projects and opportunities using objective frameworks, ensuring scarce resources flow to highest-impact work.

Workflow automation

Connect triggers to actions across systems so repetitive tasks happen automatically and teams can focus on work that requires judgement instead of admin.
