An IPO provides 1) a fundraising opportunity 2) a liquidity event 3) an opportunity to fulfill contractual obligations

One of the conditions of their recent debt financing was that they IPO within a certain time frame. If they believe that they don't need additional funding at the moment or can get better terms then they are simply fulfilling criteria #2 and #3 with their unique IPO. I imagine Spotify can get decent debt financing terms b/c they have such a steady and predictable source of revenue (though not necessarily profit).

Since Dropbox is making a big push into enterprise, they are hiring a ton of high touch enterprise sales people - who can't scale in the same way an engineer can.

So majority of the brokers have brick and mortar operations that can't afford to compete on price. That leaves only the online brokers. Then the next step is to build a brand that attracts customer trust/loyalty, which is what Robinhood seems to be doing and to build a really nice experience which they do with their slick apps. Once customers (generally young ppl who are first time investors) are invested in the Robinhood platform, then Robinhood can up sell them on additional features/services (margin, options, API access etc). So sure Etrade could compete on price (I doubt they would want to since it would immediately hit the bottom line vs a new company not depending on broker fees), but if you look at it from a long term perspective eliminating broker fees is just step 1.

The long play is that it actually doesn't cost significant money per trade at an institutional level. The only reason the other major brokers charge you money is because it covers their brick and mortar retail costs (e.g. Scottrade) and it adds to the bottomline (e.g. Etrade). So Robin Hood is actually just giving this surplus to the consumer instead of keeping it for themselves, and building a user base / brand in the process. Eventually once they have enough users, they will start to up sell you for other services (e.g. checking/savings, margin trading, options trading, check writing etc).

True, but all major retail brokers sell their order flows to HFTs (e.g. Etrade used to sell its order flow to Citadel), so this is nothing new

True, but all major retail brokers allow investors to trade on margin (and charge you interest on it), so this is nothing new.

All the major retail brokers sell their order flow, so you generally eat this cost no matter who you use. In addition, the hidden cost is fractions of a penny on the dollar (so still better than the $5-7 a regular broker charges per trade anyways).

"The future is wireless!"

Since you buy the house upfront for cash and hold 10% on the corporate balance sheet, isn't that a significant price & liquidity risk taken (in addition to the usual startup risks)? Because the time at which that house is eventually sold and at what price is somewhat unknowable, how do you mitigate that risk? Overall, I think what you guys are doing is very cool - wish you the best of luck.
