Notwithstanding as written YC's description seems to match exactly what these companies are doing:
> Most people either pick individual stocks and bonds and expose themselves to high volatility, or pay very high fees to mutual fund managers and lose to the index anyway. Most people are also non-experts when it comes to portfolio rebalancing and tax optimization.
> This seems to us like something software should help solve. We’d like to see new services that make it possible to invest in super low-cost index funds (in a normal account or a retirement account), do some customization around individual stocks, and otherwise set it and forget it.
