Context

Brûlerie Camélia is a French specialty coffee brand sold via monthly subscription. Customers receive 2 or 3 250g bags of selected-producer coffees every month. The Shopify store runs on Recharge to manage subscriptions and has about 4,200 active subscribers. Monthly recurring revenue exceeds 140,000 euros.

Subscription models are extremely sensitive to churn: every lost customer must be replaced by a new one at 45 euros average CAC. The longer a customer stays, the more profitable they become. Average subscriber lifetime is a critical KPI.

The challenge

Monthly churn sits at 9.2%, meaning 1 in 11 subscribers cancels each month. Average lifetime is 4.3 months, barely enough to recoup CAC. The team senses churn is concentrated at certain journey moments but lacks precise data.

Recharge reports show overall monthly churn but don't allow cohort analysis. It's impossible to answer key questions: at which subscription month do customers leave most? Do Meta Ads customers churn differently than Google Ads ones? Do some plans (2 vs 3 bags) retain better?

Without these insights, the team flies blind and runs generic promotions without knowing if they target the right moments.

The Fullmetrix solution

Brûlerie Camélia connects Shopify to Fullmetrix and activates the Cohorts and retention module. The full 3-year subscription history is synced and cohorts are automatically built by acquisition month.

The analysis reveals a churn peak at month 3 (16%) and a second peak at month 6 (12%). In between, months 4 and 5 have stable churn around 5%. Cohorts segmented by acquisition channel show Meta Ads customers churn 2x more than Google Ads customers at month 3.

The team activates three retention scenarios via Klaviyo. At month 2, subscribers get a fidelization message with an invitation to personalize preferences (more engagement, less churn). At month 3, a free gift (branded mug) for at-risk subscribers per the Fullmetrix score. At month 5, an upgrade offer to the 3-bag plan with -20% the first month.

The results

Monthly churn -35%

Monthly churn goes from 9.2% to 6.0% in 5 months, mainly thanks to targeted interventions at months 2 and 3 that eliminate the critical cancellation peak.

Lifetime +42%

Average subscriber lifetime goes from 4.3 to 6.1 months, mechanically increasing LTV without changing AOV or price.

Average LTV x1.9

12-month average LTV goes from 195 euros to 371 euros thanks to the combined retention and upsell effect to the 3-bag plan.

Accelerated CAC payback

CAC payback goes from 2.3 months to 1.5 months, letting the brand invest more aggressively in acquisition while staying profitable.

« We knew we were losing subscribers without knowing when or why. Fullmetrix cohort analysis showed us exactly where to act. Three months later, our average lifetime went from 4 to 6 months. That's a huge shift for a subscription business. »
