CRUX
The Growth System

A system of capabilities that
compounds over time.

We think of growth as a system where each capability reinforces the others. The more we layer in, the more efficient the whole thing gets. We start with the data foundation and roll out the rest a component at a time.

The Platform

Every retainer includes the managed data warehouse, full dashboard suite, AI analyst access, and daily health monitoring. Included from day one.

Advisory Hours

3, 6, or 9 hours per month depending on your tier. Used for growth strategy, prioritisation, experiment review, and ad-hoc analysis. Direct access to the operator.

Capability Sprints

Fixed-scope, fixed-fee projects that install a specific growth capability on top of your foundation. Start with what you need and add the rest over time.

The platform and advisory hours run as a monthly retainer. Capability sprints are scoped and charged on top. See pricing →

01 Data Foundation

Unify every platform into one source of truth.

Clean, trusted data conformed to your business logic, not the platforms you operate in. All your sources flow into a BigQuery warehouse you own, so every report and every stakeholder reads from the same numbers.

Unified Data Layer

All your sources in one clean, tested BigQuery warehouse you own.

02 Defining Expectations & Focus

Know exactly when you're on or off track, every day.

Bottoms-up forecast to CM3, understand the impact of every marketing event, setup growth operations including OKRs, so you can course-correct during execution and not at the next quarterly review.

03 Build Momentum

Execute ruthlessly on your highest-impact levers.

With the forecast quantifying the expectation, we install the engine that operates against it: a structured experimentation programme, deep-dive channel audits, geo-lift tests that measure true incrementality, and a re-attribution model tuned to your channel mix.

04 Breaking the Model

Step-change growth designed to break your forecast.

Once the foundation is humming, we layer on the capabilities that create step-change growth: an AI growth analyst in Slack, advanced ML data modelling, and the operational moves that get you ready for the next phase.

Why did Meta CPA spike on Tuesday?

Crux Analyst10:32 AM

Meta CPAs rose 34% vs. the prior 7-day avg. Checkout conversion dropped simultaneously — looks like a site-side issue, not a media efficiency problem.

Checkout page load time spiked to 4.2s on Tuesday morning — correlates exactly with the CPA increase.
