For starters, in any early stage startup I'd discount by 90%+ just because it's a startup, entirely irrespective of whether I like the idea, and what investors think.
It wouldn't suprise me if the estimated value of those is negative. I.e. your wage will be lower due to "wage dumping" by gamblers. I did not find amy stats on the median or average payout.
This shall be printed in block letters in a red frame ahead of most Paul Graham essays about milk, honey and richies in startup land.
He and VCs push theirs agenda because he has hundreds of bets, while founder has one.
They play different game and are quite quiet about it.
But, yes, people ought to go into it understanding which game they're playing, and understanding that your odds are different. Not least because it might make a difference in how you judge advice from your investors.
(There's also only one decision I regret us making due to investors being too willing to take risks; in retrospect I was firmly proven right but whether the board vote going the other way would have made a financial difference in the long run I can't say)
It sucks to see "your" (at this point it did not at any point feel like it was "mine") company selling for huge amounts and get nothing or near nothing, but it's worth people understanding that a large-sounding exit does not automatically mean it represents a success.
E.g. in this case the last round in 2015 apparently valued them at over a billion. Going from a $1bn valuation to a $465m exit is not great...
It's easy for people to think these terms were onerous, but if they could get $275m (the size of the last round) at those terms they likely could've still have found significant investment at less onerous terms if they wanted less risk. They chose to take those investments.
Taking VC cash is very often a game of deciding whether you want to gamble it all on faster growth or take less risk for less cash, but with the additional caveat that the investors you take on often will cheer for the "gamble it all" option as they have many parallel bets while you as the founder has one.
I've taken VC money several times and been part of early stage VC funded startups several times (including a VC), and I wouldn't rule out doing so again at some point, but it's important to go in understanding that the VC's incentives and yours are different, but if they are too different, then taking VC money might not be right for you, and that's fine.
