AI cold calling vs human SDR: which is better?
Short answer: AI cold calling wins on cost, volume, and consistency. Human SDRs win on complex discovery and relationship building. Most modern teams run AI for top-of-funnel volume and humans for late-funnel deals.
Key facts
- Cost: AI is roughly 10-20x cheaper per hour of conversation.
- Volume: AI runs unlimited parallel calls without hiring.
- Consistency: AI never has a bad Monday.
- Nuance: Humans still win on multi-thread enterprise deals.
When to use AI
High-volume outbound, inbound triage, appointment setting, cart recovery, and after-hours coverage.
When to use humans
Six-figure ACV enterprise deals, complex procurement, or highly regulated categories.
The hybrid model
AI qualifies and books, humans close. This is the most common setup in 2026.
