Looking for some advice here -I'm a non-technical jack-of-all-trades who can handle marketing, design, sales, etc. A few months ago, I approached a friend who's quite strong as a developer to collaborate on a side project that has positive feedback from the early user research I've done. We agreed to split equity evenly.However, they have not contributed over the last few months (no line of code started), despite me checking in and reporting my progress. When I ask, they say they are busy with work, which is understandable as we both have full-time jobs in tech. However, last week when I ask them if they were still interested continuing at all, they insisted that they were but simply couldn't find the time.What gives? I'd rather them tell me upfront if they weren't interested in continuing, instead of dragging out for who knows how long. I'm also tired of checking in every few weeks with no updates.Any advice for how I should handle this situation?(Background: We both work in Silicon Valley for FANGA)
