Voice agents for sales: the BDR that doesn't sleep
Vapi, Retell, and Bland.ai built the voice infrastructure. The product layer, voice-first SDR for the long tail of small teams, is open.
Why now
Voice TTS / STT crossed the human-grade bar in 2025. The remaining work is the workflow: who to call, what to say, how to follow up. That's a CRM-shaped problem on top of a voice runtime.
The idea you could build today
Twilio number per rep. Pull leads from a CRM. Call list, talk script, escalation rules, follow-up cadence. Connect via Vapi / Cartesia for the voice itself. Per-conversation pricing.
Build stack
- ·Vapi or Cartesia for the voice runtime
- ·Twilio for the phone rails
- ·Anthropic Claude or GPT-class for the script
- ·Postgres for the call ledger

Frequently asked
What about Vapi / Retell / Bland?+
They're the infrastructure layer. The product layer, the workflow that picks who to call and what to say, is where the next category leaders ship.
