The most expensive mistake a SaaS founder can make is copying the growth playbook of a company that's further along than them. Series A companies shouldn't be running the marketing programmes of Series C companies. Companies with product-market fit shouldn't be doing what companies without PMF do. And companies at £1M ARR shouldn't be building the marketing infrastructure of a £10M ARR business. The stages of growth require different strategies, different investments, and different priorities.
This piece focuses specifically on the 1-to-10 journey — from initial traction to a point where growth is repeatable and the foundations for the next stage are in place. It's the stage I've worked in most intensively across my career, and it's the stage where I see the most wasted investment and the most avoidable mistakes.
The 0-to-1 Problem: What Not to Do
Before we get to 1-to-10, it's worth briefly addressing 0-to-1, because many founders make investments at the zero-to-one stage that they shouldn't — investments that slow them down rather than accelerate them.
Before you have genuine product-market fit — before you have customers who love your product, who'd be deeply disappointed if it disappeared, who are using it regularly and getting clear value — growth investment is premature. Not wrong, but premature. The signal that you should be focusing on finding PMF rather than scaling growth is that your retention is poor, your NPS is mediocre, or your conversations with customers reveal that they're using the product but not deriving the value you expected them to.
The most common premature investment we see at the 0-to-1 stage is content marketing. Teams hire writers, build editorial calendars, and start producing blog content at scale before they've validated who they're writing for, what their buyers actually care about, or whether organic is even the right primary channel for their business. This generates low-quality content that doesn't rank, doesn't convert, and creates technical debt (thin content, duplicate content) that takes months to clean up later.
Recognising the 1-to-10 Stage
You're in the 1-to-10 stage when you have demonstrable product-market fit — customers who love the product, retention that's good enough that the leaky bucket isn't undoing your acquisition efforts — and you're trying to build repeatable, scalable acquisition that can take you from a few paying customers to a meaningful number.
The defining characteristic of this stage is that you need to find your primary acquisition channel — the one channel where your unit economics work clearly and where you can invest more to get more, predictably. Most businesses succeed with one primary channel and one or two supporting channels. Trying to scale all channels simultaneously at this stage dilutes focus and budget, and produces mediocre results across the board.
The 1-to-10 Growth Playbook
The first priority at this stage is channel validation — running structured experiments to identify which acquisition channels have the economics to support your growth. This typically means running paid experiments across two to three channels simultaneously, with small but meaningful budget allocations, over six to eight week periods. Measure CAC, conversion rate to qualified opportunity, and early-stage retention signals from each channel. The channel with the best economics is your primary investment target.
Organic search is almost always worth investing in at the 1-to-10 stage, even though it won't generate meaningful pipeline for six to twelve months. The compounding nature of SEO means that investment made today pays dividends for years. The cost of not starting your SEO programme until you reach the 10-stage is paying a significant opportunity cost — twelve months of organic growth you'll never get back. Start building the content foundation and technical SEO infrastructure now, even if you're primarily reliant on paid for immediate pipeline.
Content at this stage should be highly specific to your ICP. Don't write for a broad audience. Write for your ten best customers — the ones who love your product, who are getting clear value, who refer others. What are their specific challenges? What questions do they type into Google? What would make their working life measurably better? Content that speaks directly to this specific audience will convert better than content targeting a broader market, even at lower traffic volumes.
The Critical Decisions at 1-to-10
Three decisions disproportionately determine whether companies successfully navigate the 1-to-10 transition. First, when to add headcount versus when to buy expertise. Hiring a full-time content writer before validating that content is a productive channel is a common and expensive mistake. Working with an experienced growth partner to validate channels and build the initial playbook before hiring to execute it is typically more capital-efficient.
Second, how to balance short-term pipeline needs with long-term channel building. The temptation at this stage is to allocate all budget to paid because it generates pipeline immediately, while deprioritising organic because it takes time. This is rational in the short term but creates a long-term trap — you remain entirely dependent on paid, your CAC stays high, and you're competing for the same increasingly expensive paid inventory as well-funded competitors. The right balance is to fund the short term with paid while consistently investing a meaningful portion of budget in building the organic engine that will eventually lower your CAC.
Third, how to price and position for growth versus for immediate revenue optimisation. Some founders discount heavily to close early customers, creating a pricing baseline that's hard to move away from later. Others price too high before demonstrating value, limiting their ability to close deals quickly enough to learn. Getting pricing and positioning right early is disproportionately impactful — it determines the economic model for everything that follows.
Setting Up for the 10-to-100 Transition
The most successful 1-to-10 journeys end with the right foundations in place for what comes next. Not just pipeline and revenue growth — but infrastructure, positioning, and channel diversity that makes the next stage of scaling achievable without rebuilding from scratch.
By the time you're approaching the 10-stage, you should have a clear ICP that's been validated by closed deals, a positioning that resonates with that ICP and differentiates you from alternatives, at least one content marketing programme that's beginning to generate organic leads, paid programmes with validated unit economics, a CRM and marketing automation setup that gives you visibility into pipeline by source, and case studies that demonstrate the specific outcomes you deliver. With these foundations in place, the 10-to-100 journey is about scaling what works. Without them, it requires rebuilding while trying to grow — which is much harder.
