IANAL, but I would guess that "optional maturity conversion" means the investor can choose to convert at those terms if the two-year window expires without a prior conversion being triggered. So if the startup doesn't raise a $1 million financing round in the first two years, the investors can grab 3% of the company at their option.

It would be strange if the company would get to choose when the investors' debt converts.

Yes, it's the investor option to convert upon maturity into Series AA, not the company option to force conversion.

OK, so in practice, what happens if the company can't raise a round? Do they just return what they can to the fund and close up the doors?

The note stays outstanding. Generally speaking, there's no good reason for the investor to want to convert into equity, as debt is better in a bankruptcy situation.

Some companies might return money to investors before shutting down.
