How valuable is building a high-quality (for-profit) event app for future EA conferences?
There are 6 eag(x) conferences a year. this number will probably increase over time and more conferences will come up as EA grows- I'd expect somewhere between 80-200 EA-related conferences and related events in the next 10 years. This includes cause-area specific conferences, like Catalyst and other large events.
A typical 2.5 day conference with on average ~300 attendees spending 30 hours = 9,000 man-hours would be a range of 720,000-1,800,000 man hours over 10 years.
