For a period of 4-6 weeks, you will receive on a weekly basis a list of several optional marketing, PR or writing tasks you can choose from. Some of them don't require too much time, and some a bit more. Among the tasks are email marketing, social media marketing, pitching reporters, offline marketing and more. For each task, there will be a different result-base bonus.
The job probably requires 5-15 hours/week, depends on the tasks.
We are a startup (backed by Y-combinator, among the first investors of Airbnb, Reddit and Dropbox and the most prestigious startup accelerator in the world). 14 weeks ago we silently launched our iOS app, Bits (think 'Who's Line Is It Anyway' meets Vine). Here're a few examples to content people created using Bits: http://getbitsapp.com/m/5CNjaRtr0ToP http://getbitsapp.com/m/T5gBe82W6J1e http://getbitsapp.com/m/HCbd2ZuA0dV
