How We Built a Multi-Industry WhatsApp AI Agent in Israel

How We Built a Multi-Industry WhatsApp AI Agent in Israel At AI Buddy , we've deployed AI agents for 200+ Israeli businesses — real estate agencies, dental clinics, law firms, gyms, and beauty salons. This is the technical story of how we built a WhatsApp AI agent that works across all of them. The Problem: WhatsApp Is Israel's Business Channel In Israel, over 90% of business communication happens on WhatsApp. Not email. Not web chat. WhatsApp. This means: Leads come in at 11pm asking about services Customers expect responses in minutes, not hours A 3-hour response time loses 80%+ of conversion opportunities One person can't respond fast enough at scale The solution isn't "hire someone to watch WhatsApp 24/7." It's an AI agent that handles the entire conversation flow autonomously.
