Introducing the Founderz Fellows: our first AI-powered mentors
At Founderz, we believe that online education should be personalized. That's why we've created Fellows, virtual AI mentors who accompany students in real time.
We are hearing more and more about AI agents. It sounds like something futuristic, but the truth is that we use them in our daily lives without even realizing it. From virtual assistants on our phones to the systems that recommend what to watch on streaming platforms, artificial intelligence agents are closer than we think.
In this article, we are going to answer questions clearly and simply, such as: what are AI agents, what are the different types, and how do they work?
AI agents: what are they, and why are they getting so much attention?
An AI agent is, in essence, a system capable of perceiving its environment, processing information, and making decisions to achieve a specific goal. They are not just programs that follow orders, but tools that have a certain degree of autonomy to solve tasks.
Imagine you ask your phone to find the best route to get home. The device not only interprets your request but also analyzes real-time traffic, calculates alternatives, and suggests the fastest option. That is a simple example of how an AI agent works.
The difference with traditional software is that the agent is not limited to executing fixed instructions. It adapts its response according to environmental conditions and available data. And that is the key to why they are so useful in a changing world full of information.
Types of AI Agents
Within the category of AI agents, we find different classifications, depending on their level of autonomy and complexity. Let’s review some of the most notable ones:
Reactive agents
They are the simplest. They respond to immediate stimuli, without having memory or the ability to learn from past experiences. A good example is programs that detect spam in emails: they analyze each message and classify it in real time.
Model-based agents
In this case, agents have an internal representation of the world. Thanks to this, they can make more elaborate decisions and anticipate consequences. For example, a self-driving car doesn’t just react to the car in front of it; it also “understands” the context of the road.
Goal-based agents
In addition to processing information, these agents pursue specific goals. They can evaluate different scenarios and choose the action that best gets them closer to their objective. A route planning system for deliveries that optimizes time and fuel consumption would be a good example.
Learning agents
Perhaps the most interesting: these are the ones capable of learning from experience and improving over time. This is where many of the current developments in machine learning and deep learning are found.
AI Agents: examples we use without realizing it
Although it sometimes seems like an abstract concept, the truth is that AI agents are already integrated into numerous aspects of our daily and professional lives. Some examples are:
- Virtual assistants like Siri, Alexa, or Google Assistant.
- Content recommenders, from Netflix to Spotify.
- Customer service systems that automatically answer basic questions.
- Search engines that adapt results based on history and preferences.
- Productivity tools that suggest how to organize a calendar or prioritize tasks.
And in the business world, AI agents are increasingly common in helping with decision-making, data analysis, and even the detection of financial fraud.
How do AI agents work?
To understand it simply, think of three basic steps:
- Perception: the agent collects data from its environment (sensors, cameras, microphones, or digital information).
- Processing: it analyzes that information using algorithms, prediction models, or internal rules.
- Action: it responds autonomously with the most appropriate decision.
Of course, this entire process can be more or less complex depending on the type of agent. The most advanced ones even include an additional learning step, where they adjust their models as they receive new information.
Why are AI agents so important?
AI agents represent a leap in how machines interact with people and their environment. Among their main advantages are:
- Automation of repetitive tasks, which saves time and resources.
- Improved efficiency in sectors like logistics, healthcare, and finance.
- The ability to personalize, offering experiences tailored to each user.
- Decision-making in complex environments, where humans may be limited by the amount of data.
According to a report by McKinsey & Company (2025), the adoption of AI-based systems could generate an economic impact of up to $4.4 trillion annually worldwide. A significant portion of this potential is directly linked to the development of AI agents.
The role of AI agents in innovation and training
Talking about AI agents not only means understanding how they work, but also preparing for a future in which they will be increasingly relevant. Companies need professionals capable of designing, implementing, and supervising these types of systems.
In this context, programs like Founderz’s AI and Innovation certificate program become a key opportunity. Our program allows professionals from different sectors to acquire the necessary skills to work with these technologies in a practical way, understanding not only the technical aspect but also their impact on innovation and business.
How to start exploring the world of AI agents?
If you are interested in learning more about the topic, we recommend a few steps:
- Familiarize yourself with everyday examples of AI agents and reflect on how they already influence your daily life.
- Read about the different types of agents to understand their differences and applications.
- Explore open tools that allow you to experiment with AI models in simple projects.
- Invest in training, as knowledge will be the key to differentiating yourself in a constantly evolving job market.
AI agents have ceased to be a futuristic idea and have become a reality that accompanies us in multiple areas of daily and professional life. Understanding what they are, how they work, and what types exist is a first step to appreciating their impact on the present and the future.
Furthermore, specialized training is essential to make the most of their possibilities. If you want to take the leap and prepare for the challenges of innovation, our AI and Innovation certificate program can be an excellent starting point.
