Y Combinator is the most prolific startup accelerator in the world, having funded companies that collectively are worth over $600 billion. For investors, tracking YC startups is one of the highest-signal deal sourcing strategies available. Companies that emerge from YC have been vetted by a world-class selection process, received intensive mentorship, and have access to the most powerful alumni network in tech. This makes YC companies a natural starting point for VC deal sourcing.
The typical YC company raises its seed round within weeks of Demo Day, often oversubscribed. Angels and seed-stage VCs who want access to the latest YC batch need to move fast and come prepared. A comprehensive YC database helps investors pre-screen companies before Demo Day, research founders' backgrounds, and understand the competitive landscape in each sector.
Beyond seed investing, tracking YC alumni is valuable for Series A and later-stage investors looking for proven companies ready to scale. Our database lets you filter by status to find top YC companies that are actively growing. Whether you're preparing for the next YC Demo Day or sourcing later-stage deals, our YC companies database gives you a complete view of the Y Combinator portfolio.
VCBacked provides verified founder contacts for YC companies and 4,150+ startups overall.
Browse YC companies by batch, industry, status, or location. Use filters to find companies matching your criteria.

Y Combinator has funded over 5,000 startups since its founding in 2005. Our database tracks the vast majority of these companies with batch information, industry classification, team size, founder details, and current status. New companies are added after each YC Demo Day.
A YC startup is a company that has been accepted into and completed the Y Combinator accelerator program. YC invests $500,000 in each company (as of recent batches) in exchange for 7% equity. YC startups go through an intensive 3-month program culminating in Demo Day, where they pitch to hundreds of investors.
The most successful YC startups include Airbnb (valued at $75B+), Stripe ($65B+), DoorDash ($50B+), Coinbase ($15B+), Instacart, Reddit, Dropbox, and Twitch. YC's portfolio includes 7 companies valued at $10B+ and dozens valued at $1B+ (unicorns). Browse our top YC companies page for the full list.

Investors track YC startups because Y Combinator has the strongest track record of any accelerator for producing high-growth companies.
