What if the winning hackers win at two of your events, and are funded for two different companies but aren't interested in the problem after the weekend - except for the running around money.
Is the money in the form of 'a gift which could be used to run a company for a couple of months'?
Who would collect the money, just one of them in their bank account?
Who monitors the teams afterwards - or is that just up to the your sponsor/the investor?
Basically, I like the idea - but I'd be tempted to use it to allow me space to concentrate on my primary software idea more, rather than a 3 day event health hackathon solution. As an investor, I'd be worried that I'd be 'herding cats' getting three teams of three random people (for example) to continue a project they don't genuinely care about and eventually have just lost that money.
How do you plan to address these concerns?
