I can only speak on behalf of my model (#3), but that's meant entirely for companies who want better visibility in their existing operations. Say, they want to figure out how much cash they have in the bank in 6 months, or can they afford to hire 3 more ppl next quarter.
Personally, I have found it hard to work with pre-revenue companies, especially if they come to me with a plan to hit tens of millions in revenue in just a couple of years since launching. Maybe a small percentage of them do, but given how many don't make even a single dollar I've tried to steer clear of pre-revenue startups. Companies with real revenue and growth seem to be a much better fit.
