Our formula for success
YC is run by startup founders who have built exactly what they wanted when starting and growing a startup.
Investor network
YC companies have raised $85 billion dollars from the best investors in the world. Our founders have access to the YC Investor Database with profiles and reviews for more than 50,000 startup investors.
YC Alumni
YC founders get to benefit from the collective wisdom of over 9000 YC alumni through Bookface, our private social network for finding advice, intros, and potential customers.
Hiring Network
Through Work at a Startup and HN, we help our founders hire the small number of early engineers and other team members critical to finding product market fit.
Top YC Companies
We put founders' interests first
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.
Exclusive deals
YC founders have access to over 1000 deals from leading software companies. Every YC company gets free credits or significant discounts worth in excess of $500,000.
Private social network
YC founders get to benefit from the collective wisdom of over 9000 YC alumni through Bookface, our private social network.
No Board Seat
We don't take a board seat. We don't demand 20% of your company. We don't take weeks/months to decide to invest.
No Hidden Fees
We don't charge fees. We don't require decks, business plans, or MBAs. We don't tell you what to do. We only offer advice.
The best written advice
YC founders get to benefit from our collective experience funding 5000 companies across almost 20 years with extensive documentation.

"At YC, we were challenged to do things that don't scale – to start with the perfect experience for one person, then work backwards and scale it to 100 people who love us."
