We decided to build a cloud-based appointment and calendar management system for beauty salons, dietitians and private clinics. I am a senior backend and database developer, and my friend is a UI/UX designer. Right now, we both plan to dedicate 15-20 hours a week alongside our day jobs to release the first working version within 6 months.
We haven't incorporated yet but we want to sort out the equity split right from the start. My friend wants to be involved not just in design but also in marketing later on, and suggested a 50/50 split. However, it seems like deploying the software server maintenance, SMS integrations, and ongoing customer requests will all fall on my shoulders long-term.
How should we balance equity copyright, and code ownership between us? If one of us leaves the project down the road, who gets to keep the designs or the codebase?
