About the batch

The batch will take place in-person at YC's campus in San Francisco. It starts with a 3-day, in-person kick-off and features weekly meetups in San Francisco. For more information, please read our FAQs.

During the batch, we invite eminent people from the startup world to speak. The founders of Airbnb, Stripe, Doordash, and Reddit often come back to tell the inside story of what happened in the early days of their startups.

Every company works with a dedicated YC General Partner, who gets to know them well and can help with a wide range of issues.  Every YC general partner is a successful startup founder themselves, has advised hundreds of startups, and works closely with a small group of startups they personally hand-select every batch.  YC companies are in a direct slack channel with their partner and meet weekly during the batch.

Similar to how many universities have a house model, each YC batch is actually several small, autonomous groups of companies. You go through YC as part of this small group of companies, have dinner with them each week, and build both personal and professional relationships. Many founders build lifelong friendships with the founders in their group.

During and after the batch, we introduce founders to people who can help with any challenge. Often, this means founders of other YC companies. Today, The YC alumni community is one of the most powerful communities in the world, and its members have a strong commitment to help one another.

Towards the end of the batch, we help companies raise additional funds by introducing them to YC’s extensive network of investors.  

YC doesn't end after 3 months. We continue to help founders for the life of their company, and beyond — and so does the YC alumni community. Read more here.
