Another significant mistake was originally budgeting close to 400k for the 1000-attendee event. It was impossible to raise that much money for this kind of event in only 5 months. Like, really, really impossible. Over time the budget shrank and shrank, until we figured we would only need $100k to pull this off. However, it was too late to focus our fundraising work effectively — we should have started off in March with a target of $100k, not $400k.
