Comparison
AI SDR vs a lead generation agency: who does the work, who owns the accounts and what you control
A lead generation agency runs outbound for you and delivers meetings. An AI SDR is software you run yourself, or have an agency run on your behalf. Choose an agency when you want the work done and have budget for a service. Choose Sellinger when you want to keep the accounts, the data and the conversations in your own workspace.
