A dedicated Sales Development Rep is the traditional way to handle inbound leads. But between the $50-80K annual cost, limited hours, and ramp-up time, many businesses are finding that AI instant callback handles the speed-to-lead problem more effectively - and at a fraction of the cost.
Even the best SDR cannot call a lead within 60 seconds of every form submission. They are on other calls, in meetings, at lunch, or simply off the clock. Research from Velocify shows that calling within 60 seconds produces 391% more conversions than calling after just 2 minutes. Every minute of delay costs you conversions - and an SDR will always have delays.

SDRs excel at complex, multi-touch outbound sequences and relationship-driven enterprise sales where a human touch over weeks or months is essential. If your sales cycle involves deep discovery calls and custom proposals, an SDR adds real value.
But for the initial speed-to-lead response - making sure every inbound form lead gets a call within 60 seconds - AI callback is faster, cheaper, and more consistent. Many teams use both: AI callback handles the instant response and qualification, then passes qualified leads to your human team for the deeper conversation.
