Without much more detail than this, they don't sound like cofounders. If they're waiting until you launch to go 100%, then you're assuming all the risk right now.

Again take with a grain of salt, bc I have no context, but , if there's one you think is clearly the best, that you like working with them, get them to be a cofounder and make them go all in. They can do lots of manual work to validate the idea/product (ie manually do things you'd like your product to do). If there's noone you could see doing this, then their role is probably not going to grow that much when there is a 'product'.

Also: the product will never be done, and framing launch as a binary event doesn't help you (or your potential cofounders). It's all just a continuous spectrum of trying to cover as much scope/utility as possible for your users, and using a product to try to automate that. After 7 years, you'd be shocked how much stuff my sales cofounder does manually that we had framed as a 'required feature for launch'.
