How to look for a technical co-founder?

I found co-founderlab to be a very useful platform. Although, it also depends on the skillset and location preference if you have any.

One of the best methods I've found is posting the job description on HackerNew's monthly "Who's Hiring" thread. I was a fairly technical solo founder and needed help with a niche application in the tech stack. I just created a post with our elevator pitch, #'s on early traction, and general stage of the business and was overwhelmed with emails. Of the submissions, I hired 2 extremely capable engineers, one of which who previously worked at a major competitor and the other with two previous SaaS exits. The best part is it didn't cost a dime, and my post was even upvoted to the top of the thread which massively helped with long-term visibility.

There are quite a few websites out there to put in touch people with ideas and people with dev skills. Some of them are listed on PH as well like Find A Maker where I found my last cofounder. But to be honest I really think PH would be the best place to help for this! We have this great community of makers and people with different skills and ideas at the same place, that would be perfect. A while ago I begged @rrhoover to implement it but I don't think it's on the way... maybe one day!
