I am going to disclaim this, by stating upfront that I have no fundraising experience. I think what I would do if I were in your shoes, would be to squeeze the roadmap, I do not think anyone would be willing to put down 500k and then wait 4/6 months before the product is even launched.

I would look for a launch in the next month.

To draw on a successful example I seem to remember twitch raised a similar sized seed, but launched 3 products in the first year before launching twitch.

Actually, I would tweak this advice a bit. Launch now as in today if that's feasible.

Thank you for thinking about this and trying to help.

I wholeheartedly agree with you in spirit. If I could launch today, I would. If I could build a launch-able version of this, by myself, in a month, I would. Sadly, though, neither of those situations are the situation I'm actually in.
