What they did
MarcoKueks, who runs a small AI agency and is not an engineer, built a WhatsApp agent for a tutoring company that books calendar appointments. He used Struere, a platform he built to handle the recurring WhatsApp-to-calendar-to-database plumbing. That let him spend most of the two days on the client's booking logic.
How it went
It shipped in two days for a $5K fee. Six months earlier, the same job took a week and a half, including days fixing messages that arrived but never triggered a booking.
Worth knowing
The speedup came from reusing a platform he had already built after repeatedly paying developers for the same stack, not from starting fresh.
Try it yourself with n8n
Build a workflow that takes incoming WhatsApp messages for [business name], asks the customer which [service] and what time they want, checks [Google Calendar name] for openings, and books the slot. Send a confirmation back to the customer. Test it with a few fake bookings and show me the results before turning it on for real customers.
