YC is run by startup founders who have built exactly what they wanted when starting and growing a startup.

The most experienced partners

Each founder is assigned a dedicated group partner who has mentored hundreds of YC companies. They have more data on what it takes to build a successful startup than any other early stage startup advisor. These group partners read applications, interview companies, and mentor startups throughout the batch. You can access them in person, over email, and on Slack.
