Love the entrepreneurial spirit! Financing, marketing, go-to-market strategy. Geon you're a beast!
The business model is ambitious, and may disrupt the usual way of things. As a veteran enthusiast, it's usually preferable to purchase a full kit for full coverage all boards.
But, if we're talking about growing this hobby, then selling 60% boards and $39 GMK kits is going to rope a lot more people in. This is an opportunity to offer higher quality keycaps at more reasonable price points.
My 2 cents is that we need more quality GMK sets in this world and less dye-sublimated clone caps. GMK needs to be able to switch up their offerings so that they can step up their game and compete in the marketplace too.
