Series A capital buys you 18-24 months to prove you can acquire customers efficiently, retain them profitably, and build a repeatable growth engine. This playbook shows you how to allocate marketing resources, hire the right people, and establish the metrics that get you to Series B.
The Problem
Founders confuse Series A with permission to scale prematurely
A $10M-$20M Series A feels like validation that it's time to scale everything — hire aggressively, launch expensive campaigns, and expand into new markets. But Series A is for proving the business model works, not for scaling it. Companies that scale before they've nailed unit economics, channel-market fit, and repeatable acquisition burn through their runway without building the foundation for Series B.
First marketing hires are either too junior or too expensive
Founders hire a marketing generalist at $80K who can execute tactics but can't build strategy, or they hire a VP Marketing at $250K who can strategize but is too senior to execute in a team of one. Neither works at Series A. You need a player-coach who can both set direction and do the work, and the hiring criteria for that person look different from traditional marketing job descriptions.
Channel experiments are run without a framework for evaluation
Series A marketing teams try paid search, content, outbound, events, partnerships, and influencer marketing — all at once, with no framework for evaluating which channels are working at what cost. Without a structured test-and-learn approach with clear success criteria and minimum viable tests, companies waste months and hundreds of thousands on channels that could have been eliminated in weeks.
Metrics complexity paralyzes decision-making
Startups either track everything or track nothing. Both are wrong. Series A companies need a focused set of metrics that answer the question investors will ask: can you acquire customers at a cost that supports your business model, and do those customers stay long enough to be profitable? Everything else is noise at this stage.
How We Help
We start with growth audit — evaluating where you actually are versus where your pitch deck says you are. We assess product-market fit signals, current customer acquisition economics, retention and churn patterns, and market positioning. This honest assessment determines whether you need to refine the model before scaling or if you're genuinely ready to build the growth engine.
Growth model development creates the quantitative framework for your marketing investment. We build a bottoms-up growth model that connects marketing spend to customer acquisition to revenue, accounting for payback periods, retention rates, and lifetime value. This model tells you exactly how much you can afford to spend on acquisition, what your target CAC needs to be, and how many customers you need to acquire monthly to hit your Series B milestones.
Channel strategy uses a structured test-and-learn approach. We identify the 4-6 most promising channels based on your buyer behavior, competitive landscape, and unit economics. We design minimum viable tests for each channel with clear success criteria and timelines. Channels that hit benchmarks get scaled; channels that don't get cut — no extended experimentation, no sunk cost bias.
Team design defines exactly who you need to hire, when, and in what order. We create a marketing team roadmap that matches hiring to growth stage — typically starting with a senior player-coach, adding channel specialists as you find channel-market fit, and building analytics capability once you have enough data to optimize. Every hire has a defined role, clear metrics, and a timeline.
Metrics architecture keeps everyone focused. We establish the 5-7 metrics that matter at Series A: CAC by channel, payback period, monthly retention/churn, pipeline generation rate, and revenue growth rate. We build the dashboard and reporting cadence that keeps your team focused and gives your board the confidence that marketing investment is producing predictable returns.
What we deliver
- Growth audit with honest assessment of product-market fit, unit economics, and scaling readiness
- Bottoms-up growth model connecting marketing spend to customer acquisition to revenue milestones
- Channel strategy with structured test-and-learn framework and clear success criteria
- Marketing team roadmap with hiring sequence, role definitions, and milestone-based timing
- Series A metrics dashboard with the 5-7 KPIs that matter for the next 18 months
Series A isn't for scaling. It's for proving the growth model works. The companies that reach Series B aren't the ones that grew fastest — they're the ones that proved they could acquire customers efficiently and keep them profitably. Build the model first, then scale it.
Our Methodology
Our 90-day Series A growth sprint starts with foundation assessment. Days 1-30 focus on growth audit, market analysis, competitive positioning evaluation, and growth model development. We pressure-test your assumptions about customer acquisition cost, lifetime value, and market size against real data.
Days 30-60 are strategy and infrastructure. We design the channel test-and-learn framework, create the team hiring roadmap, build the metrics dashboard, and develop the first wave of marketing assets. We launch initial channel tests with clear benchmarks and evaluation timelines.
Days 60-90 are execution and learning. We analyze initial channel test results, make go/no-go decisions on channel investment, refine the growth model with real data, and prepare the first marketing progress report for your board. By day 90, you have a validated growth strategy, active channels producing results, and the measurement infrastructure to optimize continuously.
How We Work
The first month is diagnostic and strategic. We deep-dive into your product-market fit evidence, customer data, competitive landscape, and financial model. We interview your early customers to understand why they bought and what almost stopped them. This phase produces the growth model and channel strategy that guides the next 18 months.
Month two is infrastructure and launch. We build marketing infrastructure — analytics, attribution, CRM, and content — and launch the initial channel tests. We help you write the first marketing hire job description and develop the interview process. We create the board reporting template that communicates marketing progress in metrics investors care about.
Month three is optimization and handoff. We evaluate channel test results, adjust the growth model with real data, and present the first quarterly marketing review. Most Series A growth engagements run 3-6 months with quarterly advisory check-ins afterward. The goal is to build the growth engine your internal team will scale.
- Validated growth model with proven unit economics
- Channel-market fit identification through structured testing
- Marketing team foundation with right-fit first hires

Frequently asked questions
How much does a Series A growth engagement cost?
Series A growth engagements typically range from $15K-$30K per month for 3-4 month projects. This is a fraction of the cost of a premature VP Marketing hire and produces the strategic foundation that makes your first marketing hire successful. The investment pays back through avoided waste — companies that skip the strategy phase typically burn 2-3x the engagement cost on channels and hires that don't work.
How long does it take to find channel-market fit at Series A?
With a structured test-and-learn approach, most companies can validate 2-3 channels within 60-90 days. Each channel test runs for 3-4 weeks with clear success criteria. The key is running tests with enough budget and time to get statistically meaningful results while cutting losers quickly. Without a structured framework, companies run unfocused experiments for 6-12 months and still don't know what works.
Should we hire a VP Marketing or use fractional leadership at Series A?
Most Series A companies should use fractional leadership for the first 3-6 months while they find channel-market fit and define the role their full-time marketing leader will fill. Hiring a VP Marketing before you know which channels work, what team structure you need, and what metrics matter is a recipe for an expensive mis-hire. Use fractional leadership to define the role, then hire someone to fill it.
What makes Winston Francois different from a growth marketing agency for Series A?
Agencies execute tactics. We build the strategic foundation and growth model that tells you which tactics to invest in. Most Series A companies don't need more marketing execution — they need the strategy that ensures execution is pointed in the right direction. We also help you hire and structure the internal team that will scale marketing beyond what any agency can do.
How do you measure whether a Series A growth strategy is working?
Five metrics: customer acquisition cost by channel, payback period, monthly retention rate, pipeline generation velocity, and revenue growth rate. If CAC is decreasing, payback period is shortening, retention is stable or improving, pipeline is growing, and revenue is accelerating — the strategy is working. We build the dashboard that tracks these metrics and present them in the format your board expects.
What if we haven't found product-market fit yet?
If you're pre-PMF, don't invest in growth marketing — you'll scale something that doesn't work. We'll tell you that in the growth audit. Instead, invest in customer development, product iteration, and finding the wedge use case where retention is strongest. We can help with positioning and customer research to accelerate PMF, but we won't run growth campaigns until the product retains users.
