Is he really lazy, or is it just the committing hours that is bothering you?
His committing hours can change significantly than your hours particularly if he is facing challenging software implementation problems. When you get such problems (and they come one after the other in a startup) the important issue becomes fixing that royal problem rather than when or how much time you are spending on it. Those become the details. If he focuses %100 on the problem fixing, when you commit definitely tends to become less and less important.
You may say, we have some communication to do in the same hours, well sometimes also it even helps to cut communication so he can figure out and finish the job.
This is for someone who is really committing his efforts though. If he's not solving any problems then best thing to do is fix the business rather than your co-founder (i.e. quit or make him quit)
