GrowthMode Marketing and similar B2B demand generation agencies are good at what they do - building content programs, running account-based marketing campaigns, and generating MQLs for B2B companies. The question is whether an agency relationship is what your company needs, or whether you need a marketing executive who owns the whole picture.
The distinction matters because agencies optimize for deliverables. A fractional CMO optimizes for revenue. Agencies report on content produced, campaigns launched, and leads generated. A fractional CMO reports on pipeline created, CAC trends, and revenue attribution. These are different accountability structures - and they produce different behaviors.
Agencies are accountable to their scope of work - the deliverables defined in the contract. If the contract says "10 blog posts and 2 campaigns per month," that's what you get. Whether those deliverables drive revenue is often outside the accountability structure.
A fractional CMO is accountable to the same outcomes a full-time CMO would own: pipeline growth, CAC, marketing-sourced revenue, and the quality of the demand generation function. These are business outcomes, not deliverable counts.
If you have a marketing leader who owns the strategy and needs execution resources, an agency like GrowthMode can be excellent. If you don't have that strategic leader, hiring an agency first is putting execution before direction - and it rarely works at the ROI you expect.
Many of Mark's clients use this model: Mark provides strategic direction as fractional CMO, and a specialized agency like GrowthMode handles execution in specific channels. This gives you the best of both - senior strategic leadership who knows what to build and how to measure it, plus specialist execution capacity without full-time headcount.
