入站线索资格审查 Agent 在不增加 SDR 的情况下将 Demo 预约量提升 3 倍

The Problem

A B2B SaaS company was converting only 2.3% of inbound form fills to booked demos. The process: prospect fills form → SDR manually reviews → SDR calls or emails within 24–48 hours → books demo if qualified. 60% of prospects never responded to the SDR's outreach — they'd already moved on or signed with a competitor.

The Agent Solution

They replaced the form with a conversational AI agent that activates immediately when a prospect shows high intent (demo request page, pricing page, or returning visitor). The agent:

1. Asks 4–6 qualification questions in natural conversation
2. Scores BANT criteria (budget, authority, need, timing) in real time
3. For qualified prospects: shows live calendar availability and books directly
4. For unqualified prospects: offers appropriate resources and sets nurture sequence
5. For borderline cases: schedules a brief human call with full qualification context

Results

• Form fill to demo booking conversion: 2.3% → 7.1%
• Demo volume: 45/month → 139/month (+209%)
• SDR time on qualification calls: -68%
• SDR time on actual selling conversations: +94%
• Lead response time: 48 hours → 90 seconds
• Demo no-show rate: -31% (better-qualified leads show up)

The Conversation Design

They tested 12 conversation flows. The winner asked qualification questions in the context of helping the prospect, not screening them: "To show you the most relevant demo, can you tell me how many people on your team would use this?" vs. "How many employees does your company have?" Same information, 3x higher completion rate.
