He is committed and we seriously believe in that opportunity. But my co-founder is already 40 years and has been working the last 15 years. He already cut back to just over 20 hours to be able to contribute more to the startup. And we do not have enough money to just quit our day-jobs. I do appreciate working with my co-founder and he does push the project forward. But since I do 80% of the work, I would appreciate a full-time partner.
