From Challenge Acquisition To A Scalable Subscription Growth Engine
Eight days. 24–31 August. Proven demand — achieved with limited time and without full backend access
£53.12 average cost per purchase. £96.87 average margin per purchase. Delivered below the agreed maximum acquisition cost
The challenge becomes the acquisition engine. The subscription becomes the long-term commercial model. Alleyoop connects the two.
A predictable, profitable and scalable subscription growth engine. Acquire them. Nurture them. Convert them. Move them into subscription. Then scale.
The business now has several important pieces in place. The app has improved. The website and offer have developed. The subscription product is live. There is an established customer database. There is a strong founder-led brand. And the Transformation Challenge itself is a proven, highly marketable product.
The opportunity now is to connect these assets through one integrated acquisition and conversion strategy.
Rather than multiple people owning individual parts of the customer journey, Alleyoop becomes accountable for the journey from acquisition through to conversion and retention marketing.
Meta Ads · Google Ads · Klaviyo · Nurture · Retargeting · CRM · Tracking · Conversion strategy
The challenge should not be viewed as an isolated eight-week campaign. It becomes the front end of the wider subscription acquisition model. If we can acquire someone profitably through a challenge and successfully migrate them onto subscription, their value to the business changes significantly.
A powerful, urgency-led acquisition product capable of bringing large numbers of new customers into the ecosystem.
The longer-term recurring revenue opportunity capable of transforming the economics and value of every customer acquired.
Build the system that connects the two — and makes the entire engine accountable to commercial performance.
The agreed maximum acquisition cost was approximately £60. We delivered below that threshold.
The campaign only ran for eight days — and we didn't have the level of backend visibility required to properly understand which customers, creatives and campaign journeys were producing the strongest commercial outcomes.
That matters because scaling without attribution means scaling partially blind.
With full access and ownership of the wider funnel, we believe we can build a much stronger acquisition system around what has already been proven.
There are three immediate opportunities. The next challenge gives us a deadline and a powerful acquisition event to build around. Current challenge customers are one of our most valuable audiences. And the existing database is a significant commercial asset waiting to be activated.
A scalable paid acquisition campaign across Google and Meta, supported by Klaviyo and retargeting — operating across two parallel routes: Waitlist Acquisition and Direct-To-Sale. The objective is to acquire challenge customers at a commercially viable CPA and build a repeatable model.
Customers completing the current challenge already know the product, know the brand, and have committed to making a change. Build the CRM and Klaviyo journey that moves those customers towards the subscription product. This is where customer lifetime value becomes significantly more important than the initial challenge purchase.
The business has built a significant database over previous challenges and campaigns — many of those people are currently dormant. Before paying to reacquire everyone from scratch, we should systematically work the audience already available. This is potentially some of the lowest-hanging commercial fruit available.
This gives us a clear top-of-funnel objective. Paid advertising, founder-led creative, lead magnets, tactical hooks and supporting content can all be used to drive prospective customers into the ecosystem.
Converting them is.
The value of the waitlist depends entirely on what happens next. That is where Klaviyo, nurture, remarketing and creative become critical.
We'll build a large audience of interested prospects ahead of launch and nurture them towards purchase — alongside targeting customers who are ready to buy immediately and progressively increasing direct-response activity as the challenge approaches.
Meta will be a major acquisition channel for the challenge. Creative will be structured around the audience and objective rather than relying on one type of content. As data develops, we continually move budget towards what converts.
Founder-led content will remain valuable — but we'll also test different hooks, customer stories, transformation-led creative, fitness-specific messaging, tactical offers and direct-response concepts.
We don't rely on one type of content. We structure creative around the audience and the objective, and let the data tell us what to scale.
Meta can create demand. Google allows us to capture people already looking for a solution. The two platforms work together.
Google also gives us another touchpoint for people who have already encountered the brand elsewhere and subsequently search for the challenge or product.
Meta creates demand. Google captures it. Together, they form a significantly more powerful acquisition system than either platform alone.
Getting someone into the ecosystem is only the beginning. The more intelligently we segment and nurture these audiences, the more value we can extract from every person entering the ecosystem.
Move interested prospects through a structured nurture sequence that builds anticipation, demonstrates value and drives challenge purchases ahead of launch.
Recover high-intent prospects who began the purchase journey but didn't complete — re-engaging them with the right message at the right moment.
Activate the audience already built across previous challenges and campaigns — moving dormant customers back into the ecosystem rather than paying to reacquire them from scratch.
Different customers need different messages. A cold prospect shouldn't receive the same journey as someone who has already completed a challenge. Someone finishing the current challenge shouldn't be treated like a brand-new lead.
There are customers completing the current challenge right now. They already know the product. They already know the brand. They've already committed to making a change.
"Do another challenge."
Treating every challenge completion as the end of the customer relationship rather than the beginning of something bigger.
"What's next?"
The subscription gives them a route to continue their progress, develop new goals and remain inside the ecosystem beyond the initial eight weeks.
This is where customer lifetime value starts to become significantly more important than the initial challenge purchase. Our immediate priority is building the CRM and Klaviyo journey that makes this conversion happen.

Early-access subscription offers
Beta campaigns and new programme launches
Before paying to reacquire everyone from scratch, we should systematically work the audience already available.
Paid retargeting can operate alongside Klaviyo to increase the number of touchpoints and bring more of that audience back into the ecosystem.
This is potentially some of the lowest-hanging commercial fruit available to the business.
The immediate objective isn't to scale it aggressively. It's to answer one critical question:
What Does It Cost To Acquire A Subscription Customer?
Acquisition cost alone doesn't tell us whether the model works. We also need to understand retention. If a customer subscribes for one month, the economics look very different from someone who remains for:
The beta campaign allows us to begin generating the data required to understand the relationship between:
CAC → Retention → Lifetime Value → Profitability
Once we know that, we can make informed decisions about scale. The current subscription price gives us one part of the equation. The beta gives us the rest.
As subscription data develops, we'll start to understand the average lifetime value of a customer. Once we have reliable lifetime-value data, we can determine how much the business can afford to spend acquiring a new subscriber while remaining profitable.
One acquisition model. A baseline understanding of subscription economics that gives us a starting point for confident investment decisions.
Another model entirely. Longer retention changes the allowable acquisition cost and opens up more aggressive paid acquisition opportunities.
The economics change significantly again. At this point, the subscription product becomes properly scalable — and we know exactly how aggressively we can grow.
A subscription doesn't naturally have the same urgency. The challenges solve that problem.
Instead of constantly needing to replace the entire customer base for every challenge, the journey becomes:
Challenge → Transformation → Subscription → Retention → Next Goal
The challenge feeds the subscription business. Regular, highly marketable acquisition events bring thousands of new people into the ecosystem — and then the system takes over.
Different customers have different fitness objectives. That gives us the opportunity to build separate campaigns and creative around different audiences — while bringing customers into the same wider ecosystem.
People looking to lose weight — the natural home of the challenge model and the core acquisition audience at launch.
Existing gym-goers, people looking to build muscle and customers moving into maintenance — a more experienced fitness audience with different messaging needs.
Customers looking for structured programming — a different creative and funnel approach that brings a distinct audience into the same ecosystem.
These audiences shouldn't necessarily receive the same message. But we don't need to solve all of that on day one. First, we prove the core model.
We want visibility across the entire customer journey — from the first touchpoint through to long-term retention. This information feeds directly back into the advertising and nurture strategy.
Lead → Waitlist → Challenge Purchase → Challenge Completion → Subscription → Retained Customer
That allows us to understand more than simply how many leads an advert generated.
If one creative generates substantially more paying customers than another, both Alleyoop and the advertising platforms need to know.
That allows us to stop scaling blindly and start scaling based on actual customer behaviour.
Full attribution is the foundation every subsequent recommendation is built upon.
When we identify a winning concept, we don't simply leave it running indefinitely. We build around it. One successful piece of creative can become multiple variations, hooks, edits and messages. The performance data tells us what to create next.
Which messages stop the scroll for cold audiences? Which messages convert warm audiences? Which messages re-engage existing customers?
Which people, which transformations, which narratives drive the strongest commercial outcomes — and how do we build more of them?
The performance data tells us what to create next. We continually identify winning concepts and build entire creative systems around them.
The objective is to enter October ready to scale rather than trying to build the machine while the launch is already happening.
Build the machine first. Then scale it in October when the launch is live and every pound of spend matters.
We increase investment behind the audiences, campaigns and creative that have demonstrated the strongest signals. And once the challenge begins, the next customer journey starts immediately: Challenge → Subscription.
Ultimately, everything comes back to commercial performance: How much did we spend? How much did we make? How long did the customer stay? Can we profitably acquire more of them?
Spend → Waitlist → Purchases → CPA → Revenue → Margin
Spend → Subscribers → CAC → Retention → LTV
Challenge Customers → Subscription Conversion → Retention → LTV
A shared WhatsApp group will keep communication fast between the team. Our account team will coordinate internally and ensure feedback, actions and requests are distributed to the relevant specialists.
Regular calls covering current performance, wins, challenges, tests, creative and immediate actions — covering: What happened? What did we learn? What are we changing? What are we scaling?
We'll work closely with Scott, Owen, Greg and the wider team around product, offers, creative and customer behaviour. There should be one joined-up strategy from acquisition through to conversion.
We aren't going to put a marketing number in a proposal and pretend paid advertising alone guarantees that outcome. The route to that level of scale needs to be proven through the numbers. But the model is clear:
Our responsibility is to build the marketing infrastructure capable of supporting that ambition.
£2,000 + VAT per month
Ongoing management and development of the Klaviyo and nurture ecosystem — maximising the commercial value of the audience being generated through all channels
Tiered fee scaling alongside monthly advertising investment
Management fee scales as spend increases — allowing Alleyoop to support the business as investment grows while maintaining the campaign management required at each stage
Our role is to maximise the commercial value of the audience being generated through paid media, organic activity, previous challenges and the existing database.
The objective is simple:
Increase the percentage of people entering the ecosystem who ultimately become paying and retained customers.
This covers management across Google and Meta, including: campaign strategy, account management, campaign builds, waitlist acquisition, direct-to-sale campaigns, subscription acquisition testing, retargeting, lookalike audiences, creative testing, audience testing, budget allocation, conversion optimisation, tracking oversight, performance reporting and scaling strategy.
At spend above £50,000 per month, the fee becomes: £4,000 + 15% of the advertising spend above £50,000.
The important point: we only move through these levels as the acquisition model demonstrates that further investment makes commercial sense. We don't scale spend for the sake of scale. We establish the CPA, understand conversion, understand customer value, then increase investment where the economics support it.
Alleyoop's responsibility is to connect those pieces and make the entire system accountable to commercial performance. We want to be judged on delivery. Not activity. Not clicks. Not impressions. Customers. Revenue. Retention. Profitability.
Launch the next challenge. Scale paid media. Drive 20,000 people onto the waitlist. Acquire at a commercially viable CPA.
Build the subscription. Fix tracking and attribution. Re-engage the existing database. Move challenge customers through the funnel.
Understand CAC, retention and lifetime value. Then increase investment where the economics support it — all the way to £1,000,000 revenue per month.
Build the acquisition engine. Build the nurture. Build the subscription journey. Prove the numbers. Then scale.
