**1) Why “Requested callback” is high-value** - It’s an explicit buying signal: the lead asks for human contact, not passive browsing. - 这是明确的购买信号：客户主动要求人工联系，而不是被动浏览。 **2) Why AI keeps this lead in C Pool** - Day 7 predicted score = **2**, far below C→B threshold **60** (and prior cumulative score = 0). - AI 评分为 2，远低于 C→B 的 60 分门槛（此前累计分为 0），因此暂不升级。 **3) Nurturing actions triggered** - Create a **sales follow-up task** for the success team within 24h. - 触发销售/成功团队 24 小时内跟进任务。 - Send a **short discovery email + calendar link** to confirm needs, budget, timeline. - 发送简短需求确认邮件与预约链接，确认需求、预算与时间表。 - No full B2B proposal yet: keep it **lightweight** until profile data strengthens. - 暂不发完整 B2B 方案，先轻量培育，等画像数据更充分再推进。 **4) Path to a 100-unit distribution inquiry** - Callback request suggests real intent; quick human response can **qualify volume + distribution scope**. - 回电请求说明真实意向，快速人工响应可确认采购数量与分销范围。 - If discovery confirms multi-seat/training rollout, AI score rises → C→B upgrade → proposal + follow-up tasks → **100-unit distribution inquiry** conversion. - 若需求确认涉及多席位/培训铺开，AI 分数上升 → C→B 升级 → 方案与跟进任务 → 转化为 100 套分销询盘。
