Ask HN: How to Find a Growth / Marketing Business Partner?

As a software developer, I've had hundreds of ideas and never really launched anything meaningful, in fact most of my products I've started never saw the light of day.

I've decided to build 12 lean side projects in a single year. I would like to find someone who has experiencing with user acquisition to partner up 50/50 on these.

I'm a bit of an introvert and have Autism, so meeting people is always a challenge for me.

My question is how would you as a dev find a partner in growth and marketing to launch businesses with little to no startup capital for marketing?
