Have an idea, now what? Collaborators?

I'm a long-removed tech guy, now attorney, that has been itching to get back in to some kind of technology-adjacent startup. I have an idea that I think solves an existing legal-adjacent problem and is just mundane enough to potentially be successful - two traits I have historically found common in most successful enterprises.

As an attorney I'm a solo practitioner and, to be frank, I'm kind of tired of "going it alone." With this project, I think I could probably muddle my way through it myself, but I'd prefer to collaborate with someone that can pick up the slack when I have to put it down, etc.

Now comes the question ... what do you do in these situations? Where do you look? I have a robust network of legal professionals, but few tech folks. Do you get something started and then just try to bring someone on in a traditional hire fashion? How do you find folks to work with that are outside of your network when you can't bring any guarantees?
