Ask HN: Where does one find a remarkable designer co-founder?

My partner and I have worked together for while now, both in grad school and on our startup projects. We have a reasonable amount of industry experience and get along very well. We're both rather technical, each focusing on different parts of the stack, both decent at hustling and customer development (although we've only done the latter for a limited amount of time, so we're still learning a lot as we go)

We are somewhat lacking from the design standpoint: our web / graphic / interaction design is at best "meh". The best solution out there will unfortunately often fall flat if presented inadequately. At this stage we believe in keeping the team to at most 3 people, and that we would be at the strongest with an additional designer-founder.

We would love to find a 3rd founder (SF area, although remote could work) who would take full ownership of the aesthetics of any project we undertake. He/she would own everything, from the logo of the product, to the optimal screenflow, to the pitch deck, to the MVP video. Nobody already knows everything, we certainly learn a lot as we go, but it'd still have to be someone extremely competent and flexible.

Where do we go about finding this unicorn? I feel like the problem is that as techies we're stuck in the universe of developers, with very little intermingling with the art people. It's similar to when business people complain about never finding available developers to work with (I, for example, know tons, but that's because most of my network is made of developers).

Are there online hangouts for that kind of folks? Meetups? Anywhere else where we could locate someone like that?

Thanks a lot!
