Uber is pretty bloated in the engineering department, because they are suffering from NIH syndrome, and had to implement custom solutions for everything. They could certainly be much leaner in that regard.
I work on a SaaS product, we have a really small team. Accordingly we can't afford a lot of NIH when it can be avoided.
I talked to a semi-competitor and they noted they built a thing, we have that thing too ... 24 different devs on that project and they do have some extra features ... but it took them 9 months of 24 devs (not all full time granted) and my boss and I hammered it out in a week.
Our customers are using it, meanwhile they haven't sold it to anyone.
Now I'm sure there are advantages to their work but as far as what it does ... pretty much the same thing as far as core functionality goes :O
The amount of cycles NIH can scoop up is astounding.
