If one startup in five "succeeds" and the average return is 5M after 5 years of work, then the expected annual "salary" is 200K. Not a completely unreasonable figure for investment banking (I have no clue what the real numbers are. Plus, not everyone can work in wall street or do a startup)
If that's the case, then a startup would be similar to a lottery ticket. Do it for the thrill, do it for the experience, but don't do it for the money.
I suspect if you look at the new inclusions in Forbes 400 list over the past 10 years, that list (of deltas) would be dominated by Finance. This is not a good thing.
Only one post-Bubble company (Facebook) currently looks like it has a good shot at making its founder a billionaire. Compare to newly minted finance billionaires Steven Cohen, James Simons, Peter Thiel (also the founder of PayPal, but he made his billion in finance, not software), Ray Dalio, John Paulson, Kenneth Griffin and dozens more.
However, you could do a crude back of the envelope calculation now, based on average exits for series A funded companies. I believe the average (again, dominated by the big wins) is on the order of $100m. If you assume founders have 10% at exit, that's $10m. Currently 20-25% of YC funded cos raise series A. So if you ignore startups that don't raise series A (which could be an increasingly large mistake), you get a lower bound of $2m to $2.5m per founder.
Interesting. I'd never done that calculation.
The bogusness of it, of course, is evident from the fact that your expected value is so dependent on the performance of the other startups we accept. If 100% of the startups we funded went on to raise series A, the expected value would jump to $10m. And of course we have no idea how well YC funded startups will do compared to series A funded startups in general.
Side question: You seem more aware of YC contribution to startup performance. Does this mean you see YC more as competing with other investors and less with graduate programs (I think I recall you mentioning that on some old thread).
If the really big exits are dominating the figures, then that will make the odds of your startup "solving the money problem" seem larger than they really are.
But for a back-of-envelope calculation this could be a pedantic quibble.
Present value for $2.5m received in 5 years using a 15% rate (say you are accounting for high risk) is about $1.2m.
Solved?
Is that counting all the series A funded companies which never exit? $100M sounds about right to me as an average exit size, but only after excluding non-exits.
