10 emerging companies to see from the Y25 Demo day
Y Combinator, one of the most startups in Silicon Valley, held its experimental day in the winter of 2025 on Wednesday, where the latest batch of 160 startups. Some successful startups in Silicon Valley – including Stripe, Airbnb and Reddit – have started in the YC batch.
Today, YC’s latest startups focus on building the next big thing in artificial intelligence. In this batch, we have noticed a sudden number of startups that create tools to reinforce AI agents for other companies. Instead of building artificial intelligence agents, these startups build support tools. There is no shortage of companies that build artificial intelligence agent tools today, but managed to stick to the crowd.
There are some honorable signals that did not make this list completely, but they are still able to attract our attention. There is Optifye, a startup that builds programs to manage factory workers and has been involved in social controversy a few weeks ago. There are also artificial societies, which runs the simulations of Amnesty International to test the success of LinkedIn’s leaflets in a simulation version of your network.
YC has always accepted some eye -catching companies, but below startups that we believe are worth paying attention to in YC W25.
What do you do: A remote post -applications programming interface
Why is it a favorite: One of the main reasons that Waymo has succeeded in spreading independent robots is that humans can seize a vehicle remotely if someone stumbles. I took the same idea, remotely, and building a platform applied to all agents of artificial intelligence. It says abundantly that her application programming interface allows her to arrest when artificial intelligence agent fails, and one of his human operators is allowed to intervene and control.
What do you do: Artificial intelligence agents allow browsers to navigate
Why is it a favorite: Likewise, the use of the browser went earlier this week because the Chinese Amnesty International agent, Manus, used the open source tool to click on the site lists and fill the models on browsers. QUINTUPLed daily downloads, tell one of the founders Techcrunch. Since artificial intelligence customers describe the web like an Openai operator, it seems that the use of the browser provides a convincing open source tool.
What do you do: It replaces the work of hard grades with artificial intelligence
Why is it a favorite: Teaching assistants (TAS) are the backbone of any modern university, quietly for professors and doing other works. But rating the piles of frequent leaves may not be the best use of TA time when students can teach directly. Gradewiz was founded by Cornell Tas, which publicly announces that they “hate the grades”, Gradewiz uses AI tools to automate the task so TAS can benefit better than their time.
What do you do: Robinhood for Pokemon Cards
What is preferred: MISPRINT has a great origin-her co-founder, Eva Hergeit, has left her job in Goldman Sachs to sell full-time Pokemon cards, reaching $ 40,000 per month. Now, Herget and its co -founder launched a platform for selling cards and other holdings that allow users more likely to be treated with stocks, using the BID/ASS system. It is not a small market: $ 3.5 billion of Used Pokemon Cards is sold every year, says MISPRINT.
What do you do: Artificial intelligence is used to find the best Vapi programmers
Why is it a favorite: The “VIBE coding” with the help of AI is all anger, as a YC partner recently said that a quarter of the YC startups have a 95 % symbol of artificial intelligence. But coding with AI is not just fraud: it is a skill in itself. Nextbyte says it helps companies find the best “programmers” thanks to the artificial intelligence model that displays corresponding questions for programmers ’test skills to take advantage of artificial intelligence.
What do you do: Amnesty International Reproduction for Zoom calls
Why is it a favorite: Who did not emerge in a meeting to enlarge with a bad condition of bed hair or barely hidden parallel pants? Pickle solves this by allowing you to “clone” the perfect version yourself and put this individual that consists better on the screen, and the lips synchronize your voice in the actual time. As one team (mostly), we really hope that the pickle – which says that more than 1500 users are paying so far – can withdraw this amount.
What do you do: Artificial intelligence agents to automate restaurants
Why is it a favorite: We have worked enough jobs waiting for tables to know that the restaurant management is not an accurate science. Restaurant stocks are often managed in Google leaves, including a lot of connection and email with suppliers. Rebolt tries to automate some of this work with artificial intelligence agents, and the company says it is conducting pricing discussions with the parent company of Burger King.
What do you do: Roomba for weeds on the farm
Why is it a favorite: Herbs kill farms, but removing these herbs is a difficult task that requires a lot of human work. The Red Barn Robotics, founded by the leading Apple hardware, is a robot of weeds, which is called “The Field Hand”, is 15x faster than humans and a quarter of the price. The company has already signed $ 5 million in Lewis for the upcoming growth season.
What do you do: Ancient clothing market sponsored by Amnesty International
Why is it a favorite: If you have been shopping for old clothes online, then you know that it may be an enormous experience. There are a lot of options, and it is difficult to evaluate quality. Retrofit AI is used to sort thousands of old menus and create a market based on current trends. In addition, their website looks great.
What do you do: Independent periodic boats
Why is it a favorite: The autonomy is hot in the defense technology at the present time, from the “AI Fighter Pilot” from SHIELD AI to the independent Sarat Military Factory from Saronic. Splash adopts small periodic boats that independently wander the borders of the sea. The startup says it has already wandered 200 miles in the San Francisco Bay area and demands a wonderful group 800 miles.
