Have you had a conversation with him about it? The co-founder relationship's not the same as an employee/er relationship. Maybe he feels like you're bossing him around and he's unhappy about that. Maybe something is going on in his private life that's distracting. Maybe he's just bored - after all, finishing a project is paradoxically more difficult from starting one.

In the absence of information from him, do you think that it's worth finishing the product? You could almost certainly find a freelancer to finish it, but that's going to take cash that could be invested elsewhere.

I'd talk with him before contacting a freelancer, though. Unless you're planning on butting him out completely, he could see this as you going behind his back.

I have had a conversation. He thinks the product will 100 % be a failure and therefore finishing it is a waste of time, but I think that conclusion is far from certain and am actually very excited to launch it. Unfortunately, I have failed to convince him otherwise.

Have you guys tried gathering committed users (and not just interested users or people who casually say they like the idea) prior to launch? It's the easiest way to know whether or not there is a chance it might work depending on how many people are even excited about the idea genuinely. Not to mention this should be a step you guys should do regardless rather than wait for a finish product to find customers.

How many hours of work does he estimate it will take?

[purpleclock]

He refuses to give me an estimate...this is worrying me as well.

Cut him off. You need someone who will do what they have committed to do, not someone who lets their feelings and emotions control them.
