* after getting funded by YC. This deck without the YC stamp would probably not be sufficient for serious investors for a variety of reasons: Missing market size, addressable market, and market growth, doesn't answer the question of "why now"? (whereas why this and why you is answered). It isn't a bad deck but let's be honest here.
VCs who will fund you already agree there's a potential market and are willing to make a speculative bet based on patterns like data + open source that have worked in other investments. Market numbers tend to be more or less imaginary at this point.
