Multi-channel conversational AI with per-client knowledge bases, automated follow-up, and agency-scale deployment infrastructure
Small and mid-size service businesses share a common failure point: they miss leads. A customer sends a message on Instagram, Facebook, WhatsApp, or calls and gets voicemail — and by the time someone responds, the lead has moved on. Manual follow-up is inconsistent. There is no qualification logic. No system ensures every lead gets worked the same way. This problem exists at every individual business, but the structural challenge was different: how do you solve it for hundreds of businesses simultaneously? Each client has different services, different pricing, different FAQs, different brand voices. A generic chatbot cannot answer client-specific questions. A per-client custom build cannot scale economically. The agency needed a platform that delivers intelligent, per-client conversational AI across every messaging channel — deployable to a new client in minutes, not weeks — and sustainable at margins that support a growing agency business model.
A multi-tenant SaaS platform spanning the full engagement lifecycle: Inbound Message Flow: every inbound message across all four channels routes through a single path — webhook reception, orchestration, per-client knowledge base query, a single GPT call returning structured JSON (lead classification + response text), and reply delivery on the original channel. Per-Client Knowledge Bases: each client gets a dedicated vector store. When a client uploads a PDF or URL (price list, FAQs, service areas), the system automatically handles chunking and embedding. Every AI reply queries that client's context before responding. Lead Classification Engine: every inbound is automatically classified as HOT, WARM, or LOW with the CRM pipeline updated simultaneously. Missed-Call Text-Back: when a call is missed, an SMS fires within seconds containing a personalized message and booking link. If no reply, a follow-up sequence activates at 20 minutes, 2 hours, and 24 hours. Tiered Product Architecture: Tier 1 (Engagement System) covers multi-channel AI messaging, missed-call response, lead qualification, and automated follow-up. Tier 2 (Growth System) adds review automation, no-show reduction, old-lead reactivation, customer win-back, and pipeline automation — all running continuously with zero monthly administration. Agency Infrastructure: landing page, Stripe billing integration with setup fees and recurring charges, automated onboarding flow, and a master deployment snapshot that makes a new client operational in under 15 minutes.
