I'd like to correct you on that, Oscar is not just a pretty design smacked on-top of an insurance company. It's the entire insurance stack redesigned from the ground up.
Algorithms and ML are all heavily used in analyzing member data to improve the lives of people.
We're engineering systems that give us real-time feedback on the insurance system as a whole, rather than the usual "30-60 days". Building a claims system from scratch is not an easy feat.
If you'd like to learn more about what we're doing i'd be happy to demo it for you.
Don't be fooled by our pretty and simplified website. It's all of the hard engineering efforts that you don't see that make the simplified experience possible. :)
