Please please please communicate with your co-founders! Communication is absolutely necessary for your continued survival and success. Do not avoid talking about the issue because it's uncomfortable. Rather, you need to face it head on.

My co-founders and I are constantly discussing uncomfortable but important company issues. We've built up enough trust such that we understand everyone has the company's best interests in mind. Sometime we get upset while having these conversations, but the long term result is always better.

We also have regular 1-on-1s with all of our employees, and one uncomfortable question we always ask them is: "what is the worst part about working here?" Then, we fix it. Our rational is that if we can always fix everyone's worst problem, then everyone will be very happy in the long term.

On a semi-related note, I'm sorry to hear that your co-founders aren't working as hard as you. That's unfortunately a terribly common issue, and it's exacerbated by the fact that they don't appreciate the technical work that you do. I wish there was some easy way to fix that, but I fear that that along with the lack of communication among you will spell doom for your company.
