Applying to YC? Study these applications first.
YC Insights holds the reconstructed application of every company on this page, filterable by batch, industry and country, next to 60,000+ investors who fund startups like yours.
About this list
This list is part of Round Funded, an investor database and outreach platform for founders. It covers 60,000+ active VCs, angels, family offices and accelerators with verified contacts, lets you send pitches from your own Gmail, and includes a free Data Room for your raise.
Frequently Asked Questions
How many Y Combinator companies are in San Francisco?
This directory lists 2,743 YC companies in San Francisco, out of 6,207 across every batch since 2005. The count updates when the directory is refreshed, and every one of them is on this page with a link to its public profile.
Are the YC applications on these pages real?
No. YC keeps submitted applications private. Every application linked from this list is a reconstruction: the real YC form questions, answered from the company's public data. The Company section is free on each page; the rest opens in YC Insights.
Which companies on this page are best known?
Airbnb, Algolia and Amplitude lead the table above. YC marks 46 of the 2,743 companies here as top companies, its own list of the highest-valued and highest-revenue alumni.
How do I use this list when applying to YC?
Pick five companies on this page whose product is closest to yours, read their reconstructed applications side by side in YC Insights, and note how each answers the same question. Then write your own answers to that standard.
Where does this data come from?
From YC's public company directory, refreshed by batch, with each company's status, industry and location as YC reports them. Round Funded adds the reconstructed application and the founder profiles; nothing private is published.
