Having read most of your websites, as your blog suggests: I am absolutely crazy.

More to the point I am in awe of what you have accomplished on your own. Curious as to how you funded the work to date. The book value of your work, equipment procured and product development costs would have to be very substantial.

I perceive Gemini Stimdeck as being a valuable, but very niche product. I'm not surprised that VCs are disinterested. High production costs and small highly specialised market. That is the exact opposite of being a potential unicorn.

Have you considered going down the aquihire path? Have you explored the option of selling the IP, etc to your former employer or one of their competitors?

Whatever you do, don't rush. You have created very valuable IP and deserve to profit from your years of dedication to your vision.
