Ask HN: How many businesses/startups run on Cloudflare?

We all heard multiple stories of launching on AWS or GCP but wondering if its same to launch a business on the cloudflare platform. They are chepaer to run compared to AWS/GCP and I dont hear too mmuch about this and wondering if there is something I miss. In this particular case, I can even refer customers who want private cloud to create a cloudflare account which would save them money relative to their private cloud on AWS/GCP. Looking for any experience or guidance on this
