"As a visionary who clearly doesn't mind getting her hands dirty and has design skills you seem like every tech co-founder's dream! I'm honestly surprised you had difficulty finding a tech co-founder before launching."

The difficulty wasn't in finding a tech cofounder — I had one back in the day, went through a whole "interview" process with people from my original post that got on HN. The problem was knowing someone long enough to feel comfortable with them and finding the right person for the industry, especially since I'm working in the weddings industry which is generally uninspiring for a lot of devs. So it ended up with me working solo for over a year, and the right person approached me, which worked way better.

"I'm dabbling with the idea of becoming a tech cofounder for someone, so I'd like to know what were the criteria that you looked for in a tech cofounder and how did you finally find one?"

Personality and fit with you and the company is number #1. Fit within the current needs of the company was #2. Right skillset wasn't considered (hell, if I can pick it up, someone who specializes in software development certainly can.) But definitely finding someone who you can work with is the most important, because if things go badly, you can work together on a new idea if you jive well together.

What would you say about trying to identify a potential co-founder's underlying motivation (money, experience, small team/flexibility, fame, actually caring about the market, etc.) for joining a start-up?

I'm actually asking from the perspective of a technical person who finds it hard to trust/gel with potential non-tech founders, but I thought perhaps you had some thoughts :)
