Mine isn't particularly exciting or inspiring, but somebody has to be first to respond. I'm working on a mobile optimized, Bitcoin powered MTurk company called Labl (<a href="https://labl.ml" rel="nofollow">https://labl.ml</a>). I have a few reasons:<p>1. This is my first company, so I figure starting with something simple and low-capital would be nice (not interested in capital, currently a student, etc). Most of my concerns are with litigation and running a business in general<p>2. I like Bitcoin, and I figure an easy way to increase adoption is to make it lower friction to earn. Contractor payments are only done in Bitcoin for the time being, client payments are done through Stripe. Having both options for both types of users is on the list<p>3. I'm a numbers guy, and it seems like there are a lot of interesting optimization opportunities running any automated platform at scale<p>The general plan is to be a platform of new reasons to pay people over the internet. We have more interesting ventures along the "find reasons to pay people" line, but are finishing this up first to test drive our infrastructure.<p>NOTE: Sign ups are broken right now, should be fixed at some point
