Series A Funding: What It Is, What Investors Want, and How to Raise It
Series A funds a repeatable growth engine. Here is the metrics bar investors hold you to, why so many companies stall here, and what belongs in a Series A pitch deck.
In this guide
Series A is the rung where fundraising changes character. Up to now, investors have been buying potential: a founder, an insight, early proof. At Series A they start buying a machine. The question is no longer “is this working?” but “is this a repeatable, efficient engine we can pour fuel into and watch grow?” Answer it with hard numbers and you raise. Answer it with a story and you stall.
It is the third rung in our complete guide to startup funding, and it follows the product-market fit you found with seed capital.
What Series A is actually for
Series A funds the building of a repeatable growth engine. You have found what works; this round funds the people, systems and spend to do it again and again, predictably. Rounds typically run 3 to 15 million dollars and are meant to last around two years while you turn a promising business into a scaling one. Carta puts the median US Series A pre-money valuation near 49 million dollars, with founders giving up around 20% of the company. In Africa, Series A cheques are both smaller and far scarcer, which is what makes this step so hard.
The word that matters is repeatable. A seed company might have grown through the founder personally closing every deal. A Series A company must show that growth happens through a system: a marketing channel that reliably produces customers, a sales motion that others can run, a product that retains without heroics. Investors are underwriting the machine, not the founder’s hustle.
The metrics bar
This is where clean numbers stop being nice-to-have and become the entire conversation. Series A investors will hold you to a real bar. The exact thresholds vary by model and market, but the shape is consistent.
- Consistent revenue growth. Usually measured as recurring revenue (monthly or annual) growing steadily, month after month. Investors want a trend, not a spike.
- Clean unit economics. An LTV to CAC comfortably above three to one, and a CAC payback period under roughly twelve months. This proves each customer is genuinely profitable and that growth does not simply burn cash.
- Strong retention. Low churn, and for many models net revenue retention above 100 percent, meaning your existing customers spend more over time even before you add new ones. Retention is the foundation the whole engine sits on.
- Predictable acquisition. Evidence that when you put money into a channel, customers come out the other end at a stable cost. Predictability is what makes growth fundable.
- A model that reasons. Your financial model must connect and justify its assumptions, because at Series A investors will pull it apart.
If seed was about proving people love the product, Series A is about proving the economics of getting more of those people work, at scale and on repeat.
What belongs in a Series A pitch deck
The Series A deck is an investor-grade document that defends a spreadsheet. The classic ten-slide structure still holds, but every slide now carries evidence.
- Cover. Company, one-line positioning that says what you do and for whom.
- Problem. Tighter than ever, and validated by the customers you now have.
- Solution and product. The product as it exists, with real usage behind it.
- Traction. The centrepiece. Revenue growth over time, cohorts, retention curves. Show the trend clearly and explain any seasonality rather than hiding it.
- Business model and unit economics. ACV or ARPU, CAC, LTV, payback, gross margin. Label actuals versus projections honestly.
- Market. Bottom-up sizing tied to your actual go-to-market, not a slice of a global figure.
- Go-to-market. The engine: which channels work, at what cost, and why they scale. This is what the money funds.
- Competition. A fair map, including incumbents and the status quo, and your durable advantage.
- Team. The people who will build the scaling organisation, and the key hires this round funds.
- Financials and the ask. Three-year projections at a high level, the raise amount, use of funds by category, and the milestones the capital unlocks, ideally the efficient growth that sets up Series B.
The test for every slide is simple: does it help an investor believe the engine is real and repeatable? If a slide only sells vision, it belongs at seed, not here.
Why so many stall here
The step from seed to Series A is the graveyard of promising startups, and the numbers prove it: only 15.4% of the 2022 seed cohort raised a Series A within two years, down from over 30% for the 2018 cohort, according to Carta. The reason is structural. Seed money can produce growth that looks impressive but is not repeatable: growth bought by spending without real fit, or driven by a founder who cannot be cloned. That growth cannot survive Series A diligence, because the numbers do not hold up when an investor asks what it costs to win a customer who stays. The companies that clear the bar are the ones that used seed to build genuine economics, not just a bigger top line.
The African angle
In African markets this step is even harder, because Series A cheques are far scarcer than seed cheques and the economics are unforgiving. Customers are often price-sensitive, infrastructure adds cost, and if you raise in dollars while earning in local currency, a devaluation can quietly wreck the very unit economics an investor is underwriting, which is why managing currency risk is a Series A survival skill, not a footnote. The flip side is opportunity: a founder who walks into a Series A conversation with genuinely clean, defensible numbers stands out sharply, precisely because so few can. Disciplined pricing and working capital are often what make African unit economics clear the bar.
What good looks like
You are ready for Series A when you can show, not assert, that your growth is a machine: revenue climbing steadily, customers staying, each one profitable within a sensible payback, and a channel that reliably turns spend into more of them. When that engine is running efficiently and the question becomes how far and fast to scale it, you have reached the next rung: Series B.
FAQ
Frequently asked questions
How much do you raise at Series A?
Typically 3 to 15 million dollars. In Africa, Series A rounds often sit in the 5 to 15 million dollar range and are far scarcer than seed rounds, which is why the seed-to-A step is where many companies stall.
What metrics do Series A investors want?
Consistent revenue growth (often measured as monthly or annual recurring revenue), clean unit economics with an LTV to CAC comfortably above three, a CAC payback under about 12 months, strong retention or net revenue retention, and evidence that your customer acquisition is predictable rather than lucky.
Why do so many startups fail to raise Series A?
Because the bar jumps from "is this working?" to "is this a repeatable, efficient machine?" Companies that grew at seed by spending without real product-market fit or clean economics cannot show the predictable, efficient growth Series A investors require, and the round stalls.
What is the difference between a seed and a Series A deck?
A seed deck shows early proof and promise. A Series A deck must prove a repeatable model with hard metrics: cohorts, unit economics, growth efficiency and a working go-to-market engine. The burden of evidence is much higher, and vision alone will not carry it.
