Executive Summary

Small and medium businesses that rely on WhatsApp for customer inquiries—roughly 50 million firms globally—regularly lose leads that arrive after 7 PM because staff are offline or messages are triaged manually, resulting in lower conversion and frustrated buyers in markets where messaging is primary. These missed interactions are concentrated in retail, services, F&B and local commerce where immediate conversational responses materially influence purchase decisions. You could build an LLM-driven after-hours assistant that runs on the WhatsApp Business API to conduct multi-turn, natural conversations, qualify intent, capture contact details, provide product information, schedule callbacks, and pass a concise lead summary and score to CRM or morning staff. Core capabilities would include language detection for priority markets, vertical templates, compliance with WhatsApp policies and a lightweight admin dashboard for agents to review and escalate. This market is attractive now because conversational commerce adoption is rising, LLMs make natural multi-turn automation viable, and API commoditization lowers integration friction; together they support a $12.0B TAM (50M businesses × $240 ARR) with a market score of 92/100 and revenue potential rated 90/100. That said, WhatsApp policy constraints, API and model inference costs, and the need to demonstrate measurable conversion uplift versus simple autoresponders are practical risks. To differentiate in a medium-competition landscape you’ll need verticalized models and onboarding that deliver fast time-to-value, rigorous A/B evidence of conversion lift, hybrid human escalation and strong privacy/SLA commitments—assets that are defensible through accumulated training data and workflow integrations rather than generic chat behavior. The main execution challenges will be keeping unit economics healthy across languages and markets while navigating platform rules.
