The week of December 15-23, 2025, showed that AI agents are becoming one of the most exciting and important technologies in the world. AI agents are different from regular chatbots like ChatGPT because they can do more complex jobs and make decisions on their own. They learn from information in a company's systems and can handle tasks that would normally take a person a long time.

One of the biggest announcements came from PolyAI, a company in London that specializes in AI that talks on the phone. PolyAI raised $86 million from major investors to help large hotels, casinos, and other businesses use AI to answer customer calls in many different languages. The company already works with famous hotels like Marriott and Caesars Entertainment. With this new money, PolyAI will make its AI better at understanding what people want and will expand to more countries around the world.

Mindoo, a healthcare company in Antwerp, Belgium, received €5 million to build AI agents that help in hospitals. The goal is to reduce the amount of paperwork and routine tasks that nurses and doctors have to do so they can spend more time with patients. This shows how AI agents are not just useful for business and money, but also for helping people stay healthy.

Ankar, a company in London that helps with legal work, got $20 million to grow its AI agents that handle patents and intellectual property. This money will help the company expand into the United States and hire more workers. Patent work is very complicated and requires reading through thousands of documents, which is exactly the kind of job AI agents are great at doing quickly and accurately.

Another exciting development was Unconventional AI raising $475 million to build special computer hardware designed specifically for AI agents. This shows that investors are willing to spend huge amounts of money because they believe AI agents are the future of technology. Runware, a company in San Francisco, also raised $50 million to make AI work faster and better across different systems.

According to research, there are now over 1,000 different agentic AI products that companies can choose from. These tools help with everything from writing computer code to managing money to serving customers. The report mentions that companies like Salesforce have sold 18,000 different Agentforce deals, which shows how quickly businesses are adopting this technology.

Big companies like Capital One and PepsiCo are already using AI agents to do real work. Capital One created an AI agent called Chat Concierge that helps people buying cars. This AI asks questions about what kind of car they want and sets up appointments with salespeople. The results have been amazing—the AI makes people 55% more likely to buy a car. At first, the AI was a little slow, but Capital One made it 5 times faster by building their own special version.

PepsiCo is testing AI agents in three areas: helping with technology and data work, answering customer questions, and making employees' jobs easier. The company found that both customers and workers are excited to use the AI agents. They also discovered that AI agents were better than expected at testing software and finding problems that humans might miss.

Experts say that even though companies are moving quickly, most of them are still in an early stage called "pilot mode." This means they are testing AI agents before using them for everything. A research company called Gartner predicts that by 2028, AI agents will make 15% of everyday work decisions in companies. This shows that AI agents are still new, but they will probably become much more common in the next few years. Companies need to be patient and take time to learn how to use these tools the right way, but the results so far show that AI agents can help people work faster and better.
