Request a callAgency or in-house demand generation: a side-by-side comparison
By Hojabr Sattari. Updated .
An in-house team gives you product depth, continuity and control; a specialist agency gives you senior skills across channels, platform experience and speed without hiring. Most enterprise teams do best with a hybrid: in-house ownership of strategy, messaging and sales alignment, and an agency for specialist execution such as paid media, Demandbase or 6sense operation, marketing operations and GEO, all reported in one pipeline view.
At a glance
| Criterion | Specialist agency | In-house team |
|---|---|---|
| Time to productive | Weeks | Months to hire and ramp |
| Breadth of skills | Paid, ABM platforms, ops, CRO, GEO in one team | Usually a few generalists or one specialist per hire |
| Product and customer depth | Builds over time with access to your team | Deep from day one |
| Cost structure | Monthly retainer, flexible | Salaries, benefits, tools, management time |
| Continuity risk | Contract changes | Turnover and vacancies |
| Best use | Specialist execution and platform operation | Strategy, positioning, sales alignment |
What in-house teams do best
Positioning, product knowledge, relationships with sales and long-term ownership of the brand are hard to outsource. These should stay in-house whatever model you choose.
What agencies do best
Specialist skills that are expensive to hire one at a time: paid media across several platforms, Demandbase or 6sense operation, CRM attribution, CRO testing and GEO. An agency that has run these for many enterprise teams brings patterns you would otherwise learn slowly.
How to make a hybrid work
- One owner inside your team for priorities and decisions
- Shared weekly review with marketing and sales
- Reporting from your CRM, not the agency’s dashboards
- You own every ad account, dataset and document
Which one fits your team
Choose Specialist agency when
- You need senior specialist skills now
- You run several channels or platforms
- Hiring would take months or a full team is not justified yet
Choose In-house team when
- The work is core, continuous and specific to your product
- You can hire and retain specialists
- Volume justifies dedicated full-time roles
Frequently asked questions
Is an agency cheaper than hiring?
For specialist skills across several channels, usually yes, because one retainer replaces several hires plus their tools and management time. For a single continuous role at high volume, hiring can be cheaper over time.
Will an agency work with our in-house team?
A good one should. PlanConversion often runs one program, such as ABM or RevOps, alongside in-house teams and other agencies, with shared reporting.
