One of the commonest accelerators of startups in the Silicon Valley, Y Combinator, organized on Wednesday the Demonstration Day of the Winter 2025, showing what its latest party 160 startups is cooking. Some of the most successful startups of the Silicon Valley – including Stripe, Airbnb and Reddit – began in the YC party.
Today, newer startups are focused on building one other great point in artificial intelligence. In this party we noticed a surprising variety of startups creating tools improving agents and other firms. Instead of building their very own AI agents, these startups build support tools. There is no shortage of firms building AI agents tools today, but they managed to knock down from the crowd.
There are several honorary references that have not fully created this list, but we still managed to attract our attention. There is Optifye, a startup that builds a factory management software and has been involved in social controversy a few weeks ago. There are also artificial societies that work AI simulations to examine how well your LinkedIn posts In the simulated version of your network.
YC has at all times accepted the eye -catching company, but here are the startups, which we think is value listening to in yc W25.
What does it do: API for agent teleoperation
Why is this favorite: One of the key the explanation why Waymo managed to implement autonomous robotaxia is that individuals can handle the vehicle remotely if someone ever gets stuck. It took the same idea, teleoperation and built a platform that applies it to all AI agents. Abundant claims that his API lets you catch when the AI agent fails and allows one of the human operators to enter and take control.
What does it do: Let AI agents move in browsers
Why is this favorite: Accidentally, the use of a browser has turn out to be popular at the starting of this week, because the Chinese agent AI, Manus, used his Open Source tool to click the site menu and fill out forms in browsers. Daily download downloaded to twenty-eight,000, one of the founders said TechCrunch. When AI web browsing agents, resembling Openai operator, seem to make use of a browser, seems to supply an attractive Open Source tool that permits them.
What does it do: Replaces the tedious work of artificial intelligence assessment
Why is this favorite: Didactic assistants (TA) are the spine of every modern university, quietly assessing documents for professors and performing other grunt work. But assessing piles of repetitive documents might not be the best use of time when they will directly teach students. Founded by Cornell Tas, who openly declares that (*10*), gradewiz uses AI tools to automate the task so that TAS can higher use its time.
What does it do: Robinhood for Pokémon Cards
What is favorite: Miprint has a nice story of origin-her co-founder, Eva Herget, left work at Goldman Sachs to sell Pokémon cards full-time, earning $ 40,000 per 30 days. Now Herget and its co -founder have launched a platform for the sale of cards and other collector items that allow users to treat them more like wrestling, using the BID/ASK system. This is not a small market: $ 3.5 billion in Pokémon cards is sold every yr.
What does it do: uses artificial intelligence to search out the best atmospheric codes
Why is this favorite: The “atmospheric coding” supported by AI is rage, and the partner YC recently said that a quarter of YC startups has code bases that are generated by 95% AI. But coding assisted by AI is not only a scam: it is a skill in itself. NextByte claims that it helps firms find the best “atmospheric codes” because of the AI model, which supplies interviews with questions testing the skills of coders during the use of artificial intelligence.
What does it do: AI clone for zoom connections
Why is this favorite: Who didn’t come to the meeting with enlargement to work with a bad case of hair from or barely hidden pajamas pants? Pickle solves this, allowing the “clone” the perfect version and placing such a higher composed person on the screen, synchronizing the lips to the voice in real time. As (mainly) a distant team, we actually hope that Pickle – who says that he has over 1,500 paying users so far – can do it.
What does it do: AI agents for automating restaurant management
Why is this favorite: We worked enough work to know that restaurant management is not a exact science. Restaurant inventory management is often performed in Google sheets and includes many IE phones with suppliers. Rebolt is attempting to automate some of those works with AI agents, and the company claims that it is in conversations about valuations with the mother company Burger King.
What does it do: Roomba for weeds on the farm
Why is this favorite: Weeds kill farms, but removing these weeds is a difficult task that requires a lot of human work. Red Barn Robotics, founded by the former Apple Hardware guide, claims that his weed robot, which he calls the “hand of the field”, is 15 times faster than a man and a fourth price. The company has already signed $ 5 million in Loi for the upcoming vegetation season.
What does it do: Vintage style clothing market, run by AI
Why is this favorite: If you’ve got ever bought vintage clothing online, you know it could possibly be an overwhelming experience. There are many options and it is difficult to evaluate quality. Resrofite uses artificial intelligence to sort hundreds of Vintage lists and creates a market based on current trends. In addition, their website looks great.
What does it do: Autonomous patrol boats
Why is this favorite: Autonomy is now hot in defense technology, from “Shield AI”Fighter AI pilot“For the planned autonomous Saronic war factory. Splash builds small patrol boats that autonomously patrol sea borders. The startup claims that he has already passed 200 miles in the San Francisco Bay area and claims that there is an impressive range of 800 miles.
