My Cofounders Are Dead Weight—Should I Ditch Them?

This is my first time building a startup.

I’m building a startup that’s getting investor interest, but my two cofounders are basically interns—slow, inexperienced, and super protective of equity. I’m doing most of the work while they take weeks for basic functionality and refuse to let anyone else in.

The company isn’t registered yet, and I’ve found someone far more capable and motivated. Thinking of cutting ties and starting fresh with them. Am I being ruthless, or just making the right call? Anyone been through this?
