Side-project voice agent closes first client at $5k/month

Read original全职后端开发者业余做 voice agent，给催收呼叫中心试用后以 $5k/月签约首单客户。Agent 通过 SIP 外呼、问候、语音转文字、分类意向并做热转接。试用期后直接按替代人工成本报价，客户未砍价。
Business model
A full-time backend developer built a low-latency outbound voice agent after hours. After a free trial with a collections call center, they quoted $5k/month based on human-agent replacement value and the client accepted without negotiation. The agent dials via SIP, greets, classifies intent and warm-transfers.
Call/collections use cases have countable value (labor saved, better connect-to-conversion). Ordinary builders can trial with one local operator then charge monthly—good fit for technical freelancers.
Workflow
- Pick a countable-value scenario (collections, appointment confirmations)
- Ship a demo voice agent and offer a free trial
- Price monthly against the client’s current human cost
- Tune silence thresholds and logic from real calls
- Replicate to similar clients
