What if you're not looking for a technical co-founder? If I could find someone who (a) had a good idea of the Real Estate Technology landscape and (b) has relationships with local Brokers, I would drop everything and start my "next big thing" tomorrow.
I'm being honest. While I'm hoping to meet anyone that resembles a co-founder for that idea, I'm already working to build a business in a different industry. I'm not waiting for "just the right time", I just have some ideas in my mental queue that necessitate competent industry partners, and some that don't.
