Can you clarify why you have no employees/outsource/freelancer/etc ?
I would want to focus on that because it looks like you could invest something like 10k/mo (or ~5k/mo if you offshore) for some time and actually have less work to do in the future - the features will already be build, forever.
* Starting engineering at FAANG/other large companies
* Management at startup
In my experience, in case of large companies, if you go well on the interviews for a higher role (senior/mgmnt) you may hear "we like you but you don't have experience working at this scale". This doesn't mean you don't get an offer, just that it may not be as high as expectations.
Adding to your list:
* Checking crunchbase to see which companies recently raised money -> most of them start hiring immediatelly after and there are thousands of them
* If the company is not a giant, FAANG like, and you know some of their stack (by reading blog posts and such) you can contribute to some OSS they use and bring that up on your resume/interview. This is more spearfishing than throwing a net, but it helps if you have known 'targets'
