I'm wondering how you view technical cofounders. Is it the passion for CS that defines a technical cofounder? Or just someone who has the ability to hack stuff together, and later manage a technical team?
Dreaming of algorithms doesn't make you understand customers, help you get funding, or help you build a great team. If you love your customers, and build something they will fall in love with, the rest will follow.
OP, I think as long as you can build what you're trying to build and it's solid without serious issues, you're good enough. Most founders will end up hiring more technical people on to help with complex algorithms and such down the road. Not every technical founder have say, a PhD in Machine Learning for example, to build a complex semantic search engine (random example). As long as you're confident in your code to an extent to get the company up and running and be able to lead a technical team, you're probably good enough to call yourself a technical cofounder.
