IMO, having been involved in a co-founder dispute, in hindsight the issues were not at all petty and reflected major differences in attitudes and long-term goals of the co-founders. They SEEMED petty at the time, because people, specifically young people, tend to do a poor job of identifying core causes for interpersonal disputes. One risk of investing in young founders is that this sort of thing will happen at a higher rate than if they were older, but for a number of reasons that PG has discussed at length, the pros of generally investing in younger founders trump the cons relating to emotional immaturity.
