Christmas came early for the Y Combinator. The renowned Silicon Valley Accelerator has AI Agent Startups at the top of their wish list, and the startup community was distributed.

When Y Combinator issued a callout earlier this year, software that essentially allows more founders to build so-called “agent” AI to think of tasks independently – all entrepreneurs were the ears. According to Accelerator's startup directory, out of 144 companies in YC's Spring 2025 batch, there are 70 build agents. Many of the spring batch startups showed off their technology at YC's demo day on Wednesday.

Each batch brings together hundreds of early stage startups for a three-month sprint of product development and mentorship in San Francisco. Tens of thousands of people will be applied, and only a few will be reduced. YC invested $500,000 in every selected company, and its alumni roster includes success stories from Stripe, Airbnb, Doordash, Coinbase, Instacart and more.

2025 was when YC first ran its spring cohort, which ran from April to June.

YC Partners said they are particularly keen on startups exploring new and creative ways to leverage artificial intelligence for their first spring batch. From cybersecurity to consumer fintech and healthcare, many of the startups that cut cuts have applied Agent AI across the industry.

We dig into YC's Spring 2025 cohort and found 10 AI agent startups that will revolutionize each industry. To represent the spread of startups across the cohort, we selected many startups YC, divided into B2B, two healthcare startups, one FinTech, Consumer, and Industrials.

From technology teaching new tricks to teaching old robots to agents that help consumers apply for the best mortgage, we'll show you some of the most exciting agent startups in YC's first spring batch.
