Ridgeline's metrics have been performing a specific function for at least three quarters: making a business with deteriorating paid unit economics look like a business with excellent unit economics. The mechanism is not deliberate misrepresentation — it is structural. Blending organic and paid LTV:CAC produces a number that is mathematically accurate and practically useless. Reporting gross margin on coffee and packaging only produces a figure that overstates true contribution by £8 per subscriber per month. Measuring growth on raw subscriber count creates an incentive to acquire the cheapest, shortest-lived subscriber available.
Each of these choices made individual sense at the time they were made. Together, they created a board pack that could report a 4.1:1 LTV:CAC and 68% gross margin while cash sat flat for nine months. The central finding of this audit is that the organic business is genuinely excellent and the paid business is genuinely loss-making — and the current metric set makes it impossible to tell them apart. The one change that matters most is replacing the blended LTV:CAC with channel-segmented, observed LTV:CAC figures. That single substitution forces every other question: why is Meta under 1:1, what is the 50%-off cohort actually worth, where should the next pound of growth budget go. Everything else in this audit — the margin restatement, the churn segmentation, the missing cohort data — either follows from that change or becomes easier to address once it is made.
Here is how the 5 audited metrics break down by classification.
The type mix below sets up the metric-by-metric read that follows.
The LTV model assumes a lifetime that paid cohort data does not support.
The model assumed an 18-month average life. Actual paid cohort data shows a median of 8 months — less than half. Every LTV:CAC ratio built on £312 is structurally overstated before any other variable is questioned.
Acquisition cost is not evenly distributed — and the cheapest channel is not where growth spend is going.
Organic and referral subscribers cost less than one-seventh of a Meta subscriber to acquire, and they stay longer. The blended 4.1:1 LTV:CAC exists almost entirely because of this population — who are not the target of any active paid campaign.
Breaking the per-subscriber economics down from revenue to true contribution shows where the 68% gross margin figure breaks down.
True contribution is £11 per subscriber per month — 39% of revenue, not 68%. The missing £8 per subscriber per month, multiplied across 22,000 subscribers, is the structural explanation for three quarters of flat cash.
Every metric in Ridgeline's board pack either measures the wrong thing, blends populations that should never be averaged, or excludes costs that are incurred on every transaction. The result is a reporting framework that has concealed a structural unit economics problem for at least three quarters. The business itself is not necessarily in distress — the organic and referral flywheel appears genuinely strong, and true contribution margin of £11 per subscriber is workable if acquisition is disciplined. But the current metrics cannot be used to make rational decisions about where to spend, where to cut, or what is actually driving performance. They are not just incomplete; they are actively misleading.
