$1.8M Pipeline Revived from 8,000 Dormant Leads with a Conversica AI SDR
A three-person SDR team had 8,000+ dormant MQLs in Marketo that nobody had time to work, with an estimated $2M+ in pipeline going cold. SiyaSphere deployed Conversica as an AI SDR that held two-way email conversations and handed hot replies to human SDRs within 15 minutes. In 60 days it re-engaged the whole backlog, booked 187 meetings, and revived $1.8M in pipeline with zero SDR hours.

The challenge
- 8,000+ MQLs in Marketo had never been contacted or had gone cold.
- The SDR team was fully consumed by current pipeline, so manual re-engagement was impossible.
- The CMO estimated $2M+ in potential pipeline sitting untouched.
What we built

Brand-aligned AI persona
Configured a Conversica AI agent with a brand-aligned persona and personalised conversation threads.
- 2
Targeted re-engagement trigger
Enrolled every lead inactive for 90+ days with a Marketo engagement score above 40, focusing AI effort on leads with real prior interest.
- 3
Two-way conversations
Let the AI hold natural email conversations and answer common questions until a lead showed buying intent.
- 4
15-minute human hand-off
Routed hot responses to human SDRs within 15 minutes through a Salesforce task plus Outreach sequence enrolment.
Results
- 8,000 dormant leads re-engaged in 60 days with zero SDR hours
- 6.3% re-engagement rate (504 conversations started)
- 187 meetings booked through AI hand-off
- $1.8M in pipeline re-activated
- 30+ SDR hours per week redirected to new pipeline
Key takeaway
AI SDRs perform best on volume humans can't reach, like dormant backlogs, while humans own the conversation once intent appears. A fast, automated hand-off is what turns AI replies into meetings.
