Prewave's full supply chain risk management lifecycle.
By the time a startup raises a Series B, it has proven that customers want its product. The Series B question is different: can the company turn what works into a scalable, efficient go-to-market machine? Investors at this stage want to see a business that grows predictably, with the team and systems to keep doing it.
This guide covers the pain points founders face when pitching a Series B, the slides that matter most, and how to use our collection of 30+ Series B pitch decks to build yours.
What Series B investors look for
Series B investors are backing the scaling of a proven model. They focus on:
Predictable revenue growth: consistent performance over several quarters.
Go-to-market efficiency: how much it costs to acquire and grow customers.
Retention and expansion: customers who stay and spend more over time.
Team depth: leaders beyond the founders who can run key functions.
Category leadership: evidence the company can become the leader in its market.
The pain points founders face when raising a Series B
1. Showing that growth is repeatable
After a Series A, many companies grow quickly thanks to a few channels or large deals. Series B investors want proof that growth can be repeated and scaled.
2. Demonstrating efficient growth
Investors pay close attention to efficiency metrics, such as CAC payback, burn multiple and sales efficiency. Founders need to show growth doesn't depend on unsustainable spending.
3. Building a leadership team
Founders can't lead every function forever. Investors want to see experienced leaders in sales, marketing, product, engineering and finance, or a clear plan to hire them.
4. Expanding revenue from existing customers
Net revenue retention is one of the most important Series B metrics. Founders need to show that customers expand over time.
5. Preparing for tougher diligence
Series B diligence is deeper than earlier rounds. Clean financials, organized customer data and a solid data room are essential.
6. Defending the lead
Competitors are often raising too. Founders need to explain why their position is durable.

Series A vs. Series B: what changes
At Series A, investors want proof of product-market fit and early signs of repeatable growth. At Series B, they want a proven go-to-market engine, efficient growth and a leadership team that can scale. The deck becomes more operational and more focused on efficiency.
Common mistakes in Series B pitch decks
Showing revenue growth without efficiency metrics.
Relying on a small number of large customers.
Presenting a leadership team with no plan to fill key gaps.
Ignoring net revenue retention.
Using projections that don't match historical performance.
Arriving at diligence without clean data.
