> I'm building Fullstack AI for Defense

Yeah, I think this could be taken to a billion-dollar idea within a couple of months, if the implementation is decent.

Full-stack would probably mean, in context, something from Palantir-style data-mining and aggregation, through logistics/legal/command/etc., all the way to autonomous systems operating on the front lines.

I don't think that anything of this sort actually exists yet? I imagine it could exist, though, especially in smaller countries that feel threatened, and which have fewer layers of bureaucracy, e.g. Estonia.
