Honestly, hackathons are all about bullshit. I've attended to several hackathons and won several price(AT&T, Angelhack, ...).

And the more you bullshit the more you get close to the win. You even can win without coding, you only need a great talk with a great use case.

Hey guys - OP here:

We thought we'd share some things we did at AngelHack London. Before attending, I scoured the nets for posts like that and thought the community might appreciate this.

It's also shameless plug for our hack Penny :)

Thanks!
