How I built a Her-inspired hack in 24 hours

On January 24th of this year I had the fortune of attending hackTECH in Santa Monica, CA. Having been raised in LA, I thought it would be the perfect opportunity to invite my little brother Sam and his friend Matthew to come hack with me. I had been to 22 hackathons at that point and considered myself to be a hackathon veteran.

Sam, Matthew, and I arrived to hackTECH late Friday afternoon and started brainstorming ideas. We walked by a few of the sponsor tables to get an idea for some of the API prizes that were being offered. Lob and Microsoft caught my eye and I pitched them the idea of a Windows Phone app that lets you dictate and send postcards to your friends. I had just seen the movie Her earlier that week and was inspired by the main protagonist's job in the movie. For those who haven't seen it, Theodore is basically a love guru who writes heartfelt letters for strangers
