Analyzing AngelList Job Postings, Part 1: Basic Stats

Last month, I used AngelList data to analyze the technologies that startups use. After getting positive feedback on my analysis, I decided to dig into more AngelList data -- this time looking at job postings.  There is a lot of job posting data available via API, and Joshua Slayton from AngelList was kind enough to send me some additional data that is not available via API.  

This series will consist of two separate blog posts:

Part 1: Basic stats about popular startup locations, job titles, vesting schedules, etc. [Full disclosure: this is the least interesting/actionable post in the series]

Part 2: Salary and equity benchmarks. By role, company size, etc.

Preliminaries

I took a snapshot of all jobs on AngelList on August 31st, 2014. There were 12610 jobs posted at the time.

Please note that this is an analysis of companies found on AngelList, which creates some expected biases. For example, the data will be biased toward earlier stage startups, and away from startups in non-English-speaking countries.
