AI SDRs slash CAC by automating prospecting, personalizing outreach, and qualifying leads in real time. Instead of paying $2,500–$5,000/month for human SDRs to handle repetitive tasks, AI SDR platforms like LiBingo deliver the same outcomes for $29/month.

The ROI is clear: faster pipelines, lower costs, and higher conversion rates. For founders and sales leaders, AI SDRs are not just a cost-saving tool—they're a growth multiplier.

Why CAC Matters

Customer Acquisition Cost (CAC) is the total expense required to acquire a new customer. High CAC kills growth, especially for startups and mid-market companies.

Traditional outbound sales relies on manual SDRs, expensive data subscriptions, and fragmented tools. AI SDRs change the equation by automating repetitive tasks and consolidating workflows.
