Let's consider the few ways Indeed makes money:

• Premium job listings
• Allow employers to access resume database
• Targeted ads
• Indeed hiring events

So let's look at tech stack since Indeed is a platform company. Each of these streams are pretty distinct and will require different tech infrastructure. Each tech stack will have unique front/mid/backend requirements. A lot of work will sit here on the shoulders of the tech team on finding the most cost-efficient method to scale this to millions of users. People are also accessing this platform via different means (mobile/web) so this adds on to complexity.

And who's going to sell the services? You're going to need Sales & Marketing teams to think of customer funnel strategies to get these employers onboard. Once they are onboard, you're going to need people to service these accounts. These companies can be considered the supply side of the equation.

But which employer is going to upload their job listing or pay to access resume database if there's no prospective employee browsing or uploading their resumes? You're going to need another similar team here to take care on the demand side. There needs to be a lot of work done to get people convinced that uploading their resume and job searching on Indeed is going to be worth their time.

Recruiting is also one of those things that can turn into a complete shitshow with cross-region regulations. Indeed obviously doesn't only operate in the US, so just imagine the amount of countries it wants to sell into, and the different amount of employer regulations it needs to keep abreast on. The team here needs to be very, very solid to avoid regulatory risks.

Want to run a multi-national business? Better make sure your corporate functions are solid too then. Here lies your unsung heroes, finance folks, office ops, HR, the people making sure your IT equipment are available and functional when you're working from some remote place on the planet... list goes on.
