Hi, and congrats on the launch!

I'm curious about how this service compares to, say, the offerings of zero expense mutual funds from Fidelity of Schwab? I guess there's a lot more variety since I don't think those brokers have 50+ indexes.

Have you found or might expect to find liquidity issues or spread costs with fractional shares? I imagine that if you have an account with, say, $3000 that is trying to implement S&P500, the portfolio will me mostly if not exclusively fractional shares.

About positioning, I don't think I'd be the target audience since I just buy and hold $SPY, $VOO, $IVV. If you could convince me that I could implement, say, S&P 500 and be cheaper, more tax effective than holding those ETFs, that would be something interesting!
