Ask HN: How do I find a cofounder?

TLDR; I am technical, built a product myself last weekend, cold emailed 100s of potential users n got 3 users already (so crazy i love it :D).

1 of the 3 users absolutely loves (not likes, loves) the product. It solves a very core niche problem for the blue collar industry. He loves it to the point he already referred to his friends in the industry and we got on a 1 hr call today, he wants more features. soooo many more.

As exciting as this is, plssss tell me how can I find a cofounder? everything seems to be moving fast and i wanna move faster. YC cofounder matching is cool but what other options do I have?

Any tips from ppl who've been in this position would be super duper appreciated!

Love ya'll HN community! <3
