>Lying to YC partners is a waste of time. They won't ask for the money back, so tell them everything. All startups are chaotic shitshows. They know. They invented the phrase.
Most (all?) startups have broken things. Mine did and I tried to hide them at first. But I guess YC is at a point that, after thousands of startups, they've seen most of the patterns and just want to help you fix them. They'll help you no matter in what shape your company is.
Also, some startups plainly lie about their metrics, but those rarely get accepted to YC, from my limited experience.
That seems highly verifiable. You should only lie about things that will be hard to find out like how many women you ever slept with.
