Give each provider the same ideal accounts, relevant roles, business problem and meeting definition. Clarify exclusions, existing opportunities and which responses should go directly to your team.
An agency may provide human research, outreach, market expertise and relationship access. AI software may automate parts of research and engagement while your team manages the process. An AI-native managed service may combine automation with operational ownership.
Do not compare labels. Ask who handles inaccurate data, replies, scheduling, no-shows and follow-up, and how you will see their work.
Count subscription or service fees, setup, internal management and review time. Report booked meetings separately from meetings held and accepted opportunities. Inspect a sample of conversations to assess buyer experience.
For long sales cycles, use early qualification indicators and later revenue reviews rather than promising immediate financial ROI.
Orbb is an option when the workflow should use existing networks and the provider should help coordinate the introductions. Compare it fairly with agencies and agents that also offer relevant access or execution capabilities.
