To your point: when YC interviews companies, they are mostly very early stage and pre-revenue. What YC cares about is how much money they could make if everything goes right, and whether the team is capable of making everything go (close enough to) right over the long term. The current financial picture has minimal bearing on that. Obviously, to the extent that it does have a bearing, YC is smart/experienced enough to consider that. But again, you can glean this from a conversation better than an accounting document.
