But...what are you bringing to the table? There's 27 million software engineers. Let's say 99% of them are trash. That means there's 270,000 amazing engineers this mythical sales-machine-with-a-big-audience Founder could partner with.
Do you have any successful exits?
Have you built [Saas, B2C, Hard-tech] from the ground-up yourself before?
Have you built & managed a team of engineers?
Have you ever fundraised before? Do you have any connections?
Do you have any audience?
Do you have any product design taste?
Etc.
And let's say you do tick all those boxes. Then that's maybe an even bigger problem. Because if both of you are so amazingly talented and in-demand, are you really going to stick to it when the going gets tough (which it will)? Especially with a 500k/yr do-nothing middle management FAANG gig as your opportunity cost?
What's most likely is neither of you will tick most of those boxes, and it won't actually matter, because the market and your product's fit will weigh much heavier on your success. Better to pick a co-founder with some of those qualities that you already know and have a good level of trust with. You can absolutely figure out the rest.
