1) Total hours dev worked so far: 100, hours likely left 50-100. 2) Partner and I invested $30k so far 3) We have experience in software team management so we had a pretty good idea of what we needed from a backend dev for phase 1. 4) He is not full-time or even part-time, more like contractual basis as per his convenience. 5) We always ask for his input/suggestions, but doesn't really show it. 6) We work on Saturdays/weeknights, because my partner and I have to get money to put into the startup (and pay our devs). 7) Not expecting free work or sympathy, just expecting fair work at a fair price. 8) Dev has stated that once we get funding he'll be "more into the project" 9) Everyone has vesting options, so he'll still get something if we part ways.
I know non-tech founders get bad reps on HN and I understand each dev likely has a horror story that has developed a bias that we ask for too much in return for too little - I can't change that about HN.
I'm merely asking for two questions: 1) What would you do in my shoes? 2) How do you add another key employee/founder if we transition? As in, you've put all this time it's hard to gives the keys to the castle to a newcomer.
