How to Build the Future with Sam Altman

I think it's actually the opposite: if there's a good founder/investor relationship, the investor is an extended part of the team, is sometimes on the field (helping close job candidates or doing customer intros), and is often trying to help from the side-lines. Not all founder/investor relationships are this good, but some are.

To use your analogy, the founders are football players, and investors are somewhere between "football fan" and "football coach", but probably a lot closer to coach than fan. It's true that neither coaches nor fans are actually on the field playing the game, but coaches have way more insider info. For example, they watch players practice and have a deeper understanding of what each player can and cannot do, they know which players might be nursing injuries, how to motivate different types of players, etc. That doesn't mean a great coach could be a great quarterback, but I think lots of players would agree that a great coach knows a lot about how to become a better football player despite not being a football player themselves. (And to extend the analogy, I think coaches are good at helping players improve despite the fact that some players might lie or make excuses or paint rosy pictures or whatever.)

I think you're conflating "impressive" and "successful." I would say that based on the numbers you've given, Reddit is an impressive company (it's hard to get any company to that level of private investment and internet fame!), but it's not necessarily a successful company yet.

Being that Reddit's valuation is solely attributable to private investment and not revenue generation (so far), the only sound way to judge whether or not it is a financially successful company is based on its potential return to investors.

By the standards of most VCs in tech, a $500M exit is suboptimal, which will result in either a modest return or just getting their money back. This is not good for a firm's "batting average" when they're trying to beat the SPY with a ten year fund. They need to cover their losses (which, indutry-wide, represents approximately all of their investments), their staff and business continuity costs, their management and performance fees and still beat the market. Modest returns aren't helpful in that regard.

You also have to consider the likelihood that Reddit will transition into a mature business that can exist profitably on its own, without continually receiving significant infusions of cash. If it can't find a way to navigate out of "tech adolescence" it's not really a successful company. The last numbers I read indicated that Reddit has achieved an annual revenue of $8-10M, which is an annual return of >= 2%. Considering that the S&P's average annual return is about 7%, you could earn $10M on $500M by sticking it into an index fund and literally burning the other $25M you would have generated by doing nothing.
