A retainer is a monthly fee paid to an agency or consultant for ongoing services — buying a defined scope of work or number of hours each month. Retainers provide predictability for both sides: the client knows their budget, the agency can staff appropriately. Well-structured retainers define outcomes and deliverables, not just hours. The common failure mode: retainers that become 'hours for tasks' without strategic direction — you get execution without intelligence.
For example, a $15K/month marketing retainer might cover: fractional CMO strategy (5 hours/month), SEO content production (4 articles), LinkedIn management, paid campaign management, and monthly reporting — a defined package of outputs.
Our retainers are outcome-oriented — we define KPIs at the start and connect every deliverable to pipeline and revenue impact.

An embedded agency model means the agency team functions as an extension of your internal marketing team — not a vendor, but a partner with deep context, shared Slack channels, and attendance in team standups.
Performance Marketing
Performance marketing is any advertising model where payment is tied to measurable results — cost per lead, cost per acquisition, revenue share — rather than flat media fees.
