This weekly update shows that AI agent startups are having a very busy time getting money from investors. These companies are building smart computer helpers that can do tasks without people telling them what to do every step of the way.

The biggest news came from Sierra, which raised $350 million at a huge $10 billion company value. Sierra was started by two famous tech leaders who used to work at big companies like Google and Salesforce. They make tools that help other businesses build their own AI agents. These AI helpers can answer customer questions, search the web, and do support tasks.

Sierra's tools are special because they let companies make sure their AI agents always give the right answers. For example, a bank can make sure their AI helper always explains loans the same way. This helps prevent the AI from making mistakes or saying wrong things.

Identity checking for AI agents is becoming very important. Vouched raised $17 million to solve this problem. As more AI agents start working on websites and doing tasks like booking trips, businesses need to know which agents they can trust. Vouched makes tools called "Know Your Agent" that check if AI agents are real and safe.

Vouched also keeps a big database of AI agents so companies can look up information about any agent that visits their website. This is like having a background check system but for computer programs instead of people.

Building systems for AI agents is also getting lots of money. Kite raised $18 million to make the basic computer systems that AI agents need to work properly. Kite used to be called Zettablock and they have experience building big computer systems. Now they're making special systems just for AI agents.

Kite made something called "Agent Passport" which gives AI agents their own identity cards. They also made an "Agent App Store" where AI agents can find and pay for services they need to do their jobs.

Meeting helpers are getting smarter too. MeetGeek got €1.6 million from investors in Europe. Their AI helper doesn't just write down what people say in meetings. It can actually join conversations, turn talks into organized information, and connect with other business tools. The company has over 4,000 customers in more than 100 countries.

Recall.ai raised $38 million to help other companies build products that understand conversations. They make tools that developers can use to access recordings and information from meetings, phone calls, and computer screens. Their system processes huge amounts of video data every day and helps over 2,000 companies.

Data analysis is getting AI agents too. Isotopes came out of hiding with $20 million in funding. Their AI agent named Aidnn can answer business questions using normal language instead of complicated computer code. The company was started by someone who helped create Hadoop, which was a big data technology from years ago.

Isotopes lets business managers ask questions about their company data without needing to know how to use complicated computer programs. The AI agent can gather information from different places like finance apps and customer databases, then give answers and make reports.

International competition is heating up. From China, DeepSeek is working on new AI agents that will come out by the end of 2025. These AI helpers will be able to do multiple tasks for people with very little instruction. They will also learn and get better based on what they did before.

DeepSeek wants to compete with American companies like OpenAI. This shows that making AI agents is becoming a global competition, with companies from different countries trying to build the best AI helpers.

All of these funding rounds show that investors believe AI agents will change how businesses work. Instead of people doing repetitive tasks, AI agents will handle customer service, data analysis, meeting notes, and many other jobs. The companies getting money this week are building the tools and systems that will make this future possible.
