The Series B Marketing Playbook

A practical guide to unlocking investment by turning growth into an investable story.

Series B is the first serious growth round, the point where a business must move from promising to provable, from a risky bet to something that can scale.

At Velocity B, we’ve worked with companies navigating this step, and it’s where many otherwise successful businesses stall, because they can’t prove their growth is repeatable, credible, and worth scaling.

In this practical guide, we focus on what investors are looking for and how marketing can lead in three key areas:

  • Narrative – making the company easy to understand 
  • Execution – building a repeatable revenue engine
  • Proof – demonstrating credibility and real market traction
