Mozilla has ~700 employees just to keep an ailing browser on life support. Brave has ~250 employees, but they're building largely on Google's core engine, so they're getting a ton of engineering for free.

Browsers are massive. I'm pretty sure the complexity is exceeding the complexity of the Linux kernel. You can pull off heroics with fewer people, but if you want to build a company that brings in revenue, has a security team and a privacy team... all of sudden, it's a pretty big enterprise.
