Frequently Asked Questions

Is this the real SINAI YC application?

No. This is a reconstruction: the real YC form questions, answered from SINAI's public data (launch notes, founder backgrounds, product description). It shows how a company like SINAI would present itself to YC, not the text they submitted. Y Combinator does not publish most applications.
