The top comment of any Hacker News post about a large tech company (announcing an IPO, layoffs, etc.) is often "what do all those people do?"

I know this is a very tired topic, but does anyone have any good blog posts or articles about "what exactly is it that you all do?" Yelp having 6000 employees. I'm not surprised, I'm not mad. I just want to understand.

We were curious as well, and wanted to see what job functions were most common at some of the largest tech companies in the United States. In order to show a mix of companies with different business models, customer bases, and types of products, we analyzed the current employee bases of Yelp, Twitter, Dropbox, Pinterest, Stripe, Palantir, Slack, Snowflake, Coinbase, and Robinhood.

All data comes from LinkedIn, so it's self-reported by employees and certainly not perfect. However, there are interesting variations that show up, from the sales heavy organizations at Snowflake and Yelp to the finance heavy organizations at Coinbase and Robinhood.

We graphed the percent of employees by function for each tech company below.

Feel free to shoot us an email at with any questions about the data.
