These are great questions. In the fundraising example, the mentor wouldn't watch the pitch in full, but instead answer specific questions around a pitch, for example what valuation cap to set, KPIs to highlight, when to raise and from whom etc. The typical interaction goes beyond just one question and answer. The duration of each response is capped at 3 minutes but a mentor can respond with multiple recorded messages. The biggest reason we haven't started offering live calls yet is because of scheduling challenges; that said the asynchronous format is just a start and we are thinking about other formats and features for future releases.
