Demand Generation
Outsourcing Demand Gen: When It Works
Agencies fail at demand gen 80 percent of the time. Here is the 20 percent of cases where they work.
Outsourcing demand generation to an agency is the most common early-stage shortcut and the most common failure mode. The reason is structural: demand gen requires deep knowledge of the ICP, the product, the buyer, and the competitive landscape. An agency cannot build that knowledge in 90 days, and most engagements end in 6 months.
The 20 percent of cases where it works: paid media execution (Google Ads, LinkedIn Ads, programmatic) where the agency has technical depth and you provide the strategy and creative; specialized channels (podcast advertising, sponsored newsletters, OOH) where the agency has unique relationships; or interim coverage when an in-house demand gen leader has just left and you need bridge execution while you hire.
The 80 percent of cases where it fails: full-funnel demand gen ownership without an in-house demand gen leader, content production without an in-house content strategist, ABM execution without in-house sales alignment, or first-year demand gen at an early-stage company. In all four, the agency cannot succeed without context the company has not yet built.
If you are considering outsourcing demand gen, the test question is: 'Do we have someone in-house who can write the brief, judge the work, and own the outcome?' If yes, an agency can amplify them. If no, the agency will fail. Hire the in-house person first. Then decide what to outsource.
