Frequently Asked Questions

How many Y Combinator companies are in the Winter 2011 batch?

This directory lists 45 YC companies in the Winter 2011 batch, 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?

DrChrono, Fivestars and GOAT Group lead the table above. YC marks 4 of the 45 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.

What is Round Funded?

It lists 60,000+ active investors with verified contacts, filtered to recent investment activity, and lets founders send personalized pitches from their own Gmail, track replies, and share a free Data Room.
