Build and handover vs a retainer agency

A retainer agency runs your outbound for you every month, and pipeline stops when the retainer does. A build-and-handover practice like ours builds the system inside your tools, trains your team and hands it over, so it keeps working after we’ve gone.

When a retainer agency is the better choice

A retainer agency is likely the better choice if:

  • You’re running outbound for the first time.

  • You’re an early-stage startup.

  • You’d like an agency to run everything for you on retainer.

If that’s you, we’re not the right fit.
