Missed leads from churned interest — automated follow-ups via email & SMS

Many B2B and B2C sellers lose a material share of near-conversion prospects when interest churns—industry estimates suggest 20–40% of marketing-qualified leads go dark before a sale closes—leaving predictable, recoverable revenue unclaimed. This problem is acute for the 4,000,000 SMB and mid-market organizations in the $24.0B addressable martech/CRM spend (roughly $6,000 ACV each) that lack the engineering resources to capture server-side signals and run compliant multi-channel re-engagement at scale. The product would be an automated follow-up platform that captures first-party intent server-side, enriches and persists contactability, and runs orchestrated email and SMS/WhatsApp sequences with AI-driven copy and subject-line variants to maximize reactivation rates. Core features would include consent-first phone capture, trigger rules for churn events, automated A/B and multi-armed bandit testing, CRM/CDP integrations, and ROI dashboards that tie reopens to pipeline and revenue lift. Timing favors entry: cookieless pressures are shifting budgets toward server-side capture and first-party data strategies, large language models make rapid, personalized creative cheap to produce, and SMS/WhatsApp is seeing renewed marketing ROI as carriers and platforms stabilize rules and delivery. That confluence—plus a $24B addressable market—means companies will pay for turnkey solutions that demonstrably recover revenue within 30–90 days. To stand out you must combine robust, privacy-compliant server-side capture, low-friction integrations (HubSpot/Salesforce/CDPs), and an LLM-driven creative engine that optimizes per-contact messaging while billing on engaged contacts rather than seats. The challenges are real: competition is high, deliverability and carrier compliance (TCPA/GDPR) require ongoing engineering and legal investment, and success will hinge on clear, fast pilot outcomes that prove incremental LTV to prospects.
