Launching a subscription product on a cost per customer that pays back

Illustrative case study, not a client. This is a hypothetical case study created by AAJ to show its thinking and process. It does not describe work for a client. The brand, scenario and numbers are illustrative, based on patterns common in DTC launches.

Background

FocusGummy (fictional) sells a premium vitamin gummy for busy professionals by subscription at $40 a month, with 20% off a three-month prepay. The launch goal is the first 300 paying subscribers in 90 days. It starts from a generic Shopify product page, a small Meta and Google Ads budget, no structured testing, no retention journey and little tracking beyond purchases.

The modeled baseline

A 0.8% click-through rate, $1.00 a click and 1.2% page conversion give a blended cost per customer of about $83. At about $28 of gross profit a month (roughly 70% margin on $40), payback takes about three months.

The objective

Can FocusGummy acquire customers at a CPA its unit economics can carry, and can it build a repeatable acquisition system rather than one lucky campaign? 90-day targets: landing page conversion of 1.6–2.0%, a blended CPA of $40–56, and payback within two months.

AAJ's approach

Clarify the positioning. Move from generic vitamins to one job: busy professionals who want better focus and steadier energy in the afternoon. Core message: "Sharper afternoons in 30 seconds a day."

Redesign the landing page. Seven sections: hero with "Start your 30-day trial", the problem, solution and benefits, social proof, offer and pricing, FAQ and objections, and a repeated call to action.

Build a structured ad system. Three angles (the afternoon crash, a routine that sticks, subscription simplicity), each tested on text length, static versus light motion, and the opening hook.

Model and track CPA and payback, then iterate on the data.

Modeled performance

Cost per customer is the cost per click divided by the share of clicks that buy, so $1.00 ÷ 1.2% ≈ $83. For scale, the median Meta traffic campaign in Health & Fitness ran a 1.63% click-through rate at $0.80 a click from April 2024 to June 2025 (WordStream), and health and wellness stores converted 2.02% of visitors on average from September 2024 to August 2025 (Triple Whale). The baseline sits well below both; the strong case assumes FocusGummy only reaches them.

• Baseline: 0.8% CTR, $1.00 CPC, 1.2% conversion, about $83 CPA
• Conservative: 1.2% CTR, $0.90 CPC, 1.6% conversion, about $56 CPA
• Strong, at category benchmarks: 1.6% CTR, $0.80 CPC, 2.0% conversion, about $40 CPA
• 90-day target band: CPA from $83 to $40–56 (33–52% lower), payback in 1.5–2 months

These are modeled figures, not a guarantee. At the baseline, the 300-subscriber goal would take about $25,000 of ad spend; at the conservative case, about $17,000.

What a 90-day engagement might look like

• Weeks 1–2, foundation and audit: positioning workshop, funnel audit, unit economics review
• Weeks 3–4, build the acquisition base: new landing page, first ad angles, tracking by angle and audience
• Weeks 5–8, test and learn: iterate on creatives, audiences, offers and landing copy
• Weeks 9–12, scale and systematize: move budget to proven angles and plan the next quarter's tests
