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.
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.
We deploy autonomous AI agents to automate prospecting, personalize outreach at scale, produce content, and run always-on marketing workflows.
We don't apply a generic playbook. Every Cactus engagement is calibrated to your stage, runway, team size, and growth objectives. For Series B Companies, that means maximizing the leverage of every marketing dollar while building the foundations that compound as you grow.
