A year into a startup, your product is built and you have some traction. You see signs of growing discontent in your co-founder so you confront him to see what's up. And then he drops an issue I don't know how to address... he doesn't think the equity split we both happily agreed to a year ago isn't fair.
How would you deal with this?
This is a tough situation to deal with. You and your co-founder need to have a heart to heart talk and get everything out in the open. Only then would both of you be able to work something out.
While none of us know the full situation, here are some questions I would ask myself:
I think you can pragmatically handle this situation and avoid ending up with grudges that could potentially tank a good startup.
Most often than not, it's about making the other person feel like they own the company -- even if they have less equity than you. The same goes for employees as well. Make them feel like they own the place and they start to value the vision more than drawing a larger salary.
