I also want to mention our equity is split three ways evenly with no vesting.
Woah. Never ever do that again. You've given away the one tool that is used to deal with the issues you list.
Not to mention no VC will touch you until you include vesting. But may be you've no plans to raise funding.
Now on to your question, I would begin by making sure that they are assigned goals that are as challenging as yours. If you feel they can help with growth, make that an official part of their day to day job. They will either succeed or fa at it. They will either work hard to achieve it or not make an attempt. Either case, when you make it "official", its good for everyone and gives everyone clarity.
