Option A
In-house marketing hire
Full-time employee, dedicated to your business
Option B
Specialist agency
Outsourced team with cross-client experience
Background
The trade-off is depth vs breadth, cost vs capacity, and culture vs accountability. A great in-house marketer goes deep on your brand and integrates with operations. A great agency brings cross-industry pattern recognition, faster execution, and access to specialists you'd never hire individually.

Brand-led business where founder is the marketer

Frequently asked questions
What about hiring freelancers instead?
Freelancers work for narrow scopes (a logo, a one-off campaign). For ongoing growth requiring strategy + execution + accountability, an agency or in-house hire wins.
Can we use an agency to bridge to an in-house hire?
Yes — many of our clients start with us, learn what they need from a hire by watching the work, then bring an in-house director on with the agency continuing on execution.
How do we vet an agency?
Ask for case studies in your industry, talk to two reference clients, audit their own marketing, and require a clear monthly scope with measurable KPIs.
What if we want a small in-house team and you handle the heavy lifting?
Common and effective. We work with several clients in this hybrid model — their marketing coordinator owns content distribution and operations; we own SEO, web, and CRM.
How long should an agency engagement last?
Most growth marketing engagements need 6–12 months for organic and CRM to compound. Quarterly reviews and clear opt-out terms keep accountability healthy.
