Starting a tech business in the UK, should you find a co-founder in the US before going live? Or should you wait for the business to mature, and then find a partner in the US?
You'll find a stronger partner in a second country if you have metrics to prove you have a working business model. Decide what those metrics should be; set them as your business goals.
Start reaching out to US contacts and let them know these goals and send them regular updates showing the progress you are making. As the gap narrows between where you are and where you are heading you'll pull contacts into your story.
Those contacts will lead to others. And eventually, you'll find your US partner.
That would depend on your business, and your team?, and probably a few other things. How about posting a few paragraphs about your business?

Zeeshan - if you are planning on selling to Americans, then yes, you need to think about having an infrastructure here that understands the market. Starting a tech company without a sales/marketing oriented person, no matter where you are located is a big problem. You need to test your concept first and make sure that you are building something that people want.
Not knowing anything about your business, and your potential US expansion plans, I would generally not recommend finding a US partner before going live. One option for now may be to engage with some US advisors to help determine the market potential and market size in the US while focusing on establishing your initial presence in the UK or elsewhere.
If you are interested in benefiting from a Global EIR accelerator type thing, then you might just go for any co-founder, not necessarily a US based one. But you might need to have a team before you pitch. You don't need to worry about what stage you're at, live or not. They will look at the team first.
