From Revenue to Profit: How to Scale a Business That Actually Makes Money 

Most founders we speak to get stuck in the same trap. Revenue climbs, the team expands, the marketing budget grows – and somehow, the profit still isn’t there. 

In a recent workshop hosted by Alex Nelson, consumer growth specialist and advisor to over 35 consumer businesses globally, she shared the frameworks she uses to help founders bridge the gap between top-line growth and sustainable profitability. Her background spans corporate venture at AB InBev, private equity at Bain Capital, and hands-on advisory work with businesses including PerfectDraft, Hello Fresh, Birchbox and Goop. 

Two Goalposts 

Alex opened with a framework that reframes how founders should think about where they are and what to focus on next. 

The first goalpost is Product-Market Fit: customers want your product and will pay for it. Most founders reach this point and assume the hard work is done. 

The second is Profit-Market Fit: your cost structure works at an achievable scale. This is where a growing business becomes a sustainable one. 

Most businesses sit somewhere between the two. They have a product people want to buy but haven’t yet built the operational model that makes scaling it profitable. The danger is assuming that more revenue will solve the problem automatically. 

“Growing revenue without understanding unit economics doesn’t build value. It destroys it.” 

Not All Levers Are Equal 

The levers available to founders fall into two distinct buckets. 

The first is in your control right now: pricing, your LTV/CAC ratio, retention and repeat rate, and product quality as measured by NPS. 

The second requires scale or a structural event before you can fully optimise it: cost of goods, manufacturing, fulfilment, distribution leverage, and overhead. 

Alex’s advice was straightforward: fix the first bucket before scaling. Then know your plan for the second and start working on it early. 

The LTV/CAC Ratio 

Lifetime value to customer acquisition cost is the single most useful metric for understanding whether your growth engine is working. 

LTV = Average Order Value × Gross Margin % × Purchase Frequency 

CAC = Total Sales and Marketing Spend ÷ New Customers Acquired 

Two important points on the calculation. For LTV, always use gross margin, not revenue. Revenue-based LTV overstates the true value of a customer and will lead you to overspend on acquisition. For CAC, include all paid channels plus team time – not just ad spend. 

From Retail Price to Contribution Margin 

Before you can be confident your growth engine is working, you need to understand exactly where your margin is going. Alex walked the room through a waterfall formula every founder should be able to apply to their own business: 

1. Retail price (inc. VAT) minus VAT = Net Revenue 
2. Net Revenue minus COGS, fulfilment, and other selling costs = Gross Margin 
3. Gross Margin minus marketing (CAC allocation) = Contribution Margin 
4. Contribution Margin minus fixed costs = Net Profit or Loss 

The contribution margin is the unit-level test. If it’s negative, working on your fixed costs won’t save you. 

A Practical Example: Doubling Revenue While Improving Profitability 

Alex walked through a client she’d worked with for three years – a bootstrapped beauty DTC brand doing under £1M in revenue when they first started working together. The founder wanted to grow but wasn’t sure how aggressively to invest given limited cash. 

The starting unit economics looked like this: 

The first guardrail Alex set: only scale when first-order contribution was breakeven or positive. At 60% gross margin on a £36 AOV, the first-order gross profit was £21.60 – just above the £21 CAC ceiling. 

Then they worked on the cost structure. As gross margin improved, the CAC ceiling rose with it, giving the business more room to invest in marketing while still breaking even on new customers. 

The scaling rule was simple: set a monthly marketing budget against revenue and CAC targets. If both were hit, spend could increase by up to 20% the following month. The result: revenue doubled in 12 months, while profitability improved. 

LTV/CAC tells you whether your growth is healthy. First-order contribution tells you whether it’s sustainable. You need both. 

The Racecar Growth Engine 

For businesses looking to accelerate efficiently, Alex referenced the Racecar Growth Engine framework, which maps the four components that drive every growth model: 

1. Growth Engine – the repeatable loop that drives most of your growth: performance marketing, referrals, SEO, sales. 
2. Turbo Boosts – one-off accelerants that create spikes but don’t sustain: PR, influencer campaigns, seasonal promos. 
3. Lubricants – optimisations that help the engine run more efficiently: conversion rate, onboarding, pricing, retention. 
4. Fuel – the input that powers and scales the engine: capital, team, data, inventory. 

The diagnostic value here is in where most founders focus. They pour in more fuel — more budget — without asking whether the engine itself is working. Getting the lubricants right often delivers more growth than adding spend to a leaky model. 

On Churn, Habit, and Channel Strategy 

The session opened into broader discussion on a few recurring founder challenges. 

On high churn: if it’s a structural feature of your market rather than a fixable problem, don’t waste energy trying to eliminate it. Accept it, price accordingly, and build an acquisition model that works alongside it. Where you can, build in structured prompts – reminders, seasonal nudges, loyalty mechanics – that bring customers back without paid media. 

On channel strategy: for businesses selling across DTC, retail, and Amazon simultaneously, the unit economics look very different by channel. If pricing isn’t managed deliberately, customers will notice and arbitrage it. Design your product range and pack sizes to avoid direct comparison across channels and build fulfilment and platform fees into the model from the start. 

Alex used an example from her time at PerfectDraft. When their last-mile delivery partner changed its pricing overnight, cutting the maximum package weight from four kegs to three, the team didn’t absorb the cost. They redesigned promotions to incentivise three-keg purchases, set the free shipping threshold at that quantity, and eliminated the previous four-keg format entirely. Cost structure stabilised, customer pricing held, and most orders shifted to the new format. 

When you can’t control a cost, control the behaviour that drives it. 

Three Questions to Answer Now 

Alex closed with three diagnostics every founder should be able to answer immediately: 

1. Is your pricing realistic for a sustainable margin at scale? If not, that’s a product-market fit problem. Solve it before growing. 

2. Is your LTV/CAC above 2x? If not, you have a pricing, conversion, or retention problem. All of which is fixable before you spend more on acquisition. 

3. Do you know what it takes to get your variable costs to a healthy level? Does it require scale, a new supplier, or a structural partnership? What can you start on now?
