Is waiting to see a term sheet from a lead investor enough of a move to mitigate concerns about optics? I'm not too familiar with the series A process - is the round basically over by that point? Or is there still work to do in assembling the rest of the syndicate or an opportunity for the term sheet to be revoked? It seems like no matter what, the continuing desire of an early investor to participate on follow on rounds is a strong signal to future investors about the company (especially if it's a prominent early investor like YC) - and there will be a lot of incentive to acquire that sort of information before the funding round is finalized.
