Griffin's embedded finance market opportunity.
The Series A is where many startups stall. Raising a seed round on vision and early signals is one thing. Convincing Series A investors that you have found product-market fit and can build a repeatable growth engine is much harder. Many companies that raise a seed never make it to this next step.
This guide covers the pain points founders face when preparing for a Series A, the slides that matter most, and how to use our collection of 70+ Series A pitch decks to build yours.
What Series A investors look for
Series A investors are betting that the company can scale. They want to see that the early promise has turned into something real:
Product-market fit: customers who use the product, stay and pay.
Repeatable growth: acquisition channels that can scale predictably.
A clear business model: pricing and unit economics that make sense.
A team ready to scale: founders who can hire and lead a larger organization.
A large opportunity: a market big enough to support a venture-scale outcome.
The pain points founders face when raising a Series A
1. Proving product-market fit
Founders often feel they have product-market fit but struggle to prove it. Investors look for strong retention, organic growth, customer love and consistent usage.
2. The gap between seed and Series A
The bar for Series A is higher than many founders expect. A company can have promising traction and still not be ready. Founders need to understand where they stand and what evidence they still need.
3. Showing a repeatable growth engine
Early growth often comes from the founders' network or one-off efforts. Series A investors want to see channels that can scale with more investment.
4. Presenting unit economics with limited history
Founders need to show that each customer is profitable, or will be, even if the data covers a short period.
5. Building a hiring plan
The Series A usually funds the first big wave of hiring. Investors want to know who you will hire, in what order and why.
6. Timing the raise
Raising too early can lead to rejection. Raising too late can leave the company short on cash. Founders need to raise when their metrics are strong and still improving.
The slides every Series A pitch deck needs
Company overview. What you do and the key highlights in one slide.
The problem and solution. Brief, since investors will focus on the evidence.
Traction. Revenue, growth rate, customers and usage over time.
Product-market fit evidence. Retention cohorts, engagement, testimonials and referrals.
Go-to-market. Channels that work, their efficiency and how they will scale.
Unit economics. CAC, lifetime value, gross margin and payback period.
Market. A credible, bottom-up view of the opportunity.
Competition. Where you win and why.
Team and hiring plan. Current team and key hires this round will fund.
Financial plan and ask. Round size, use of funds and the milestones that will set up a Series B.
Seed vs. Series A: what changes
At seed, investors back the team, the insight and early signals. At Series A, they back evidence: retention, repeatable growth and a business model that works. The Series A deck is more data-driven, and every claim needs support.
Common mistakes in Series A pitch decks
Confusing early traction with product-market fit.
Showing total revenue without growth rates or cohorts.
Presenting acquisition channels that don't scale.
Leaving out unit economics.
Asking for money without a clear hiring and milestone plan.
Raising before the metrics are strong enough.
