Consider this as a strong sign that YC is looks for companies that are an "easy sell" to VCs (the same holds for products that such companies produce). You can easily guess why they want that ...
This is not (necessarily) a contradiction: they are interested in founders who can easily be marketed. ;-)
They would invest in mass produced bottled Himalayan air if they thought it would turn a quick buck.
You don’t need a product or a capable team, you just need a shiny yuppie team, an easily marketable idea and then keep selling it to greater fools that will invest in Series B / C.
I do wonder how much money has been lost by Series B / C investors in this fundamentally broken market but then again mostly likely Series B / C investors are too rich and well connected to be effected by downturns, so it balances out itself.
