SDR & Outbound Sales for Series B Companies

Series B means you're scaling aggressively — which means marketing complexity goes up exponentially. Multiple channels, a real team, and board-level accountability.

Scaling aggressively with a larger team. Marketing must operate with process, accountability, and predictable revenue contribution.

At the Series B stage, your marketing priority should be: Multi-channel demand gen, account-based marketing, and marketing operations maturity. At Series B, we focus on marketing operations maturity: multi-channel attribution, account-based marketing programs, and the reporting infrastructure that keeps the board confident and the team accountable.

⚠️ The Series B Marketing Trap

Series B companies often lose marketing efficiency as they scale — adding headcount and spend without the operational rigor to maintain unit economics. Growth without discipline burns cash fast.
