Work in the same physical space. Setup a nice place where you can both work together, if at all possible. That's probably the only way you're going to really sync up on effort. It builds empathy and camaraderie that remote work can't. It's worth whatever it costs. Realize that there's probably no startup in the history of man where work was truly 50/50. I bet Brin/Page have their own little bitter grudges with each other about the amount of effort they put in at various times. I know that was the case for Gates/Allen and Jobs/Woz. Some level of resentment may be unavoidable. If you can succeed in spite this you won't care. If you fail you'll blame it on this (but you'll probably be wrong). It may be hard, but for the success of your company it's important that you learn to overcome things like this. If you have to do 75% of the work to be successful so what? You probably couldn't have done 100% of the work, so that 25% was necessary. Even if you gave up 50% equity it was still a good deal. The most important thing is that you succeed -- not that everyone contributes the same amount of effort. Startups are all about facing reality as it is and this is part of reality.
