What is Letterdrop?

Letterdrop is a lead‑intelligence platform that aggregates signals from public conversations, competitor activity, and job changes to surface high‑intent prospects. The tool delivers real‑time alerts when a target starts a sales cycle with a competitor, a champion moves companies, or a lost deal reopens, enabling timely outreach.

Sales and marketing teams can convert these signals into automated outbound sequences with AI‑generated message drafts, then track responses and conversation flows directly in their CRM. Customizable signal rules allow users to pull data from government filings, RFPs, satellite imagery, and other external sources, enriching account scoring and prioritization.
