I have a start-up with 2 partners. One year in. All 3 of us have been full-time on development. Pre-revenue. One more person has planned to join us since initial planning began with the plan to be 25% equal split. The three existing partners put in $20k each, no salaries paid. Q1: What would be the best method to calculate the value that partner 4 needs to buy in with? Q2: We need cash to advance development. One partner and the soon-to-be are willing to provide it, about $100k each. What would be the best way to handle the cash infusion in terms of equity or loan, and how to value sweat equity of the partners not providing additional cash at this time? Thanks!
