Even if you want to build a scalable/fundable startup, stop looking for a cofounder. It's needy and the wrong motivation. Start working on the project get help from the smartest people you know / can find. Get their help in any capacity you can. You're more likely to find a cofounder indirectly through on this path than in an overt "cofounder search". Plus you'll actually be making progress.
