Twilio/AWS: a few years ago I began to see how relevant and powerful Twilio was for sending SMS notifications, IVR (phone routing), Voice and Chat. I built an SMS platform for a large electrical company in the Bahamas for billing notifications. I have added new features and built my source code out to handle WhatsApp and into other marketing needs. I have also recently built an SMS system for a local gym that connects Autopilot which is a bot that acts and feels like a real person answering questions. I am finding that this tool or AWS Lex can handle many things that a low level sales person may handle which for a small business not having the money to hire extra people, a bot could save thousands of dollars in salaries by having a bot handle many of the common questions that are asked. The end product could be a web chat, SMS message or even Facebook Messenger.
