I wonder why they don't keep statistics on jobs created o rev generated, will be interesting to see quantifiable impact created by the YC community.
This happens during YC (no pointless meetings) and afterwards (no burdensome data reporting requirements).
To put this in perspective, SalesForce employs ~12,000 (4x that) and has roughly the same market cap ($30b).
IMO, if I were YC I wouldn't be touting this number (nor am I indicating that they do currently). What's probably more important is how many new markets have been created, and therefore jobs, due to YC companies. A number which will be extremely difficult to measure unbiasly. Otherwise, this simply reinforces the notion that software is eating the world and developers are paid too much.
