The browser has become the application runtime for most purposes today, including in the enterprise. It's also on the front-line for most security threats as its functionality relies on parsing & executing untrusted and potentially malicious code safely.
It's the perfect place for security features, enforcing policies and productivity improvements. The Enterprise™ spends huge amounts of money on (often dubious) security products and productivity tools and their complexity sometimes even exceeds browsers. A paid browser that offers better security, supports policies such as restrictions or data loss prevention and productivity features (such as ad blocking, reader mode, an easy automation API) would definitely have customers.
