During my university years my boss (current, not at the time) asked if he could pitch an idea for those in class who wanted to listen instead of going on 15 min break, I think at this point he was going to pitch to investors and wanted the practice. Two or so years later I reached out to him, asking if anything had come of it (I mean he did quit a stable job at Uni to do this, might as well check up on him) and if they were looking for a summer intern and/or part-timer. Luckily everything was going well (except that startups are never smooth sailing) and I got offered an internship. A year later and I am set to work there full time at the start of September. The lesson I took away from it all was to make effort to stay in touch with people.
