> Reddit IIRC was 6 employees until they were spun out of Conde Nast in 2011. (Some of those early employees are on HN; maybe they can correct me.)

I wasn't that early, but I was probably in the first 30 employees, depending exactly how you count things.

There are start dates for most of the early employees in this file that used to power the (now removed) "team" page on the site: https://raw.githubusercontent.com/reddit/reddit-plugin-about...

The "new" field in that file is YYYYMM data for when each employee started (though, looking through it right now, some of these definitely aren't correct, but they're reasonably close at least). Figuring out when people left is a little trickier, but estimates around a few significant dates:

* Acquired by Conde Nast (Oct 31, 2006) - 4 employees

* Independence from Conde (Sept 6, 2011) - 12 employees (including 2 redditgifts from that acquisition the month before)

* $50M funding round announced (Sept 30, 2014) - 58 employees (many working on redditgifts/redditmade)

* Steve Huffman returns as CEO (July 10, 2015) - 69 employees

* $200M funding round announced (July 31, 2017) - 230 employees

And they've said that they're aiming to get to 300 by the end of 2017.
