18F is basically a contracting agency, run by and for the government. They basically take on work that's assigned to them by the USDS. The USDS does work as well, but typically more with a leadership and policy role.
Here's more info on how we came from the Presidential Innovation Fellows program: https://18f.gsa.gov/2015/03/20/one-year-in-and-looking-forwa...
I'm an 18F employee.
(I also work at 18F, and I highly recommend it)
Morale is really high. Culture and work/life balance is super important to the team and to management. People feel compelled to tweet about how much they like their job. I haven't worked at a startup, but many have and are happy to be here. There are plenty of government frustrations, but the size of the impact of our mission greatly outweighs any day to day annoyances. For me, the best thing is that when there is a problem, whether it's management, bureaucracy, or technology, the attitude is to address it openly and head on. And 18F has a group of really smart people, so those problems rarely last very long.
It's the best job I've had - I have autonomy, flexibility, and the ability to make an impact on a daily basis. It's really nice to think about how many people you reach on a daily basis. The problems you get to work on are challenging and complex - I'm learning new things every day.
I came from the journalism world, not a startup - so I can't speak to whether it's similar. I will say this: We have a "Yes, how can I help you do that?" philosophy, which I find refreshing and really delightful.
For example, right now I'm working on an onboarding Slack bot (code: https://github.com/18F/dolores-landingham-bot) that will help acclimate new employees to 18F. Got the idea. Threw it around. Everyone liked it. We're building it. And then we plan to write up how we did it, so others can use it too.
That's the best feeling - sharing what you learn, and not being afraid to go public with every bit. Happy to say more.

I wouldn't say it's a philosophical difference. We're definitely tackling the problem in two different ways, but that's not because either group thinks the other is wrong, it's because this is a big problem that requires attacking it from many angles.
