In this course, you will learn how to build powerful Voice AI agents using VAPI and potentially save a business +$300K/year.

Using a real life example, we'll design an Agent to manage inbound calls for restaurant reservations. Whether you're a business owner, an automation agency, or an entrepreneur looking to streamline customer interactions, this course provides practical, hands-on training to implement AI-driven solutions with a real-life example that’s directly applicable to your business.

Why this course when you can find all resources online?Indeed, however would you understand it and be able to execute as fast? Consider the time you'll need to search, and learn it as you go, in an unstructured way, from many mentors with different approaches, that will take you countless hours with no accountability at all. If you see the ROI of this course, that gives you a step by step structured path straight on point, to help you get what you need in just a few hours, than this is for you.We all trade time, money, and expertize. If you don't have the expertize or money but you have the time, please do the research online. If you don't have the expertize and no time to waste, then this is for you.

We’ll begin by guiding you through setting up your VAPI account and creating a simple yet powerful Voice AI chatbot capable of handling reservation inquiries, confirming bookings, and providing key information like restaurant hours and location. You’ll learn to customize the bot to handle customer queries efficiently, allowing it to respond accurately and professionally in real-time.

The course also covers integrating Twilio, the leading communication API for voice and messaging, to manage call handling for your reservation system. We will show you how to set up inbound call routing, automate responses, and seamlessly interact with customers without the need for human intervention.

You’ll then explore Make, a versatile automation tool, to design workflows that connect your Voice AI with other systems such as CRM tools, customer databases, email notifications and much more. This powerful integration ensures your restaurant's communication system runs efficiently, saving you time and effort while enhancing the overall customer experience.

ROI Perspective: see it like this, one AI Voice agent can handle 10 concurrent calls, and it's on 24/7. We're talking about 10 people per shift to do the same. In a 24/7 rota, you'll need at least 3x the work force to cover the entire day, holidays, days off, sick days and whatnot. Ultimately, this means that 1 AI agent can replace 30 people in a Customer Support Team with just one phone number and has no mood variations, and can be trained as you get more data, and it can follow business guidelines strictly.

In terms of return on investment (ROI) taking as for this example that each human agent is earning $1,250 per month, this totals a monthly cost of $37'500 to cover 30 salaries plus other expenses to the business, roughly and depending on the country and business needs, of course.  If a business can reduce the team size to 9 to audit, oversee and update the systems, and take some of the calls when human interaction is needed, we're talking about saving $26'250 every month or +$300k/year, for that specific team. That's how significant AI can be, when well integrated into a business.

With the Voice AI agent handling reservations autonomously, you save money, reduce errors, and increase efficiency—allowing your team to focus on higher-value tasks, such as customer experience enhancement and business growth. The potential cost savings make this an excellent investment that can pay for itself in a short period, all while improving customer satisfaction and operational efficiency.

By the end of this course, you will have the skills to set up a fully operational Voice AI system that can handle inbound calls, manage reservations, and provide seamless customer service—boosting your operational efficiency and reducing staff workload. Whether you’re managing one restaurant or scaling to multiple locations, you’ll have the tools to create a more efficient, automated reservation system that works 24/7.Either you want to learn and apply this to your business, or create these AI agents for other businesses, this course is for you.

Enjoy the ride.

With the new VAPI update, we need to reassess the way we send data to our knowledge base. As of now, the previous method seems to be bugged, we'll keep it there in the course, until we have a confirmation that it is deprecated. I believe that they'll find a way to keep it and to connect it to Trieve, by allowing us to create a dataset and then upload files in it.

Meanwhile, we have to do it, directly on Trieve and then connect that dataset to our VAPI account, so we can then attach the knowledge base to our assistant.
