Case Study: BusterBox achieves higher retention and LTV to accelerate MRR growth with ChartMogul

How BusterBox is using segmentation and LTV to grow to €100k in MRR

BusterBox is a Dublin-based subscription box for dogs founded in 2016 by three co‑founders with a mission to deliver healthy, affordable pet products to customers in Ireland and the UK. The team struggled with subscription‑specific challenges: high involuntary churn from expired or disposable cards, inconsistent metrics from their initial analytics tools, and the need to closely manage box costs and margins while deciding which marketing channels truly delivered valuable, long‑term customers.

ChartMogul gave BusterBox accurate subscription analytics, added requested features quickly (including multi‑Stripe support), and made LTV, cohort retention, and channel segmentation easy to track and act on. The founders now use ChartMogul daily and in weekly reviews to optimize box contents, target profitable channels, and set revenue goals — helping them improve retention, allocate marketing spend more effectively, and make strides toward their €100k MRR target.
