Not necessarily it has to be 5-20 people. it could be a team of 100-200 people too. But "~100 developers" that you mentioned, can not be small or mid-tech companies, until half or more than half of the developers are useless. 100 developers in one company have potential to built the next billion dollar product and literally change the world. As you can see, some one just mentioned, FB has 250 developers ( https://www.quora.com/How-many-software-engineers-work-at-Facebook/answer/St-Peter-6 https://www.quora.com/How-many-software-engineers-work-at-Fa... ) and some people do have mentioned they have approx 700, 900, or .... But, important factor is - they have only 25K employee (source: https://www.statista.com/statistics/273563/number-of-facebook-employees/ https://www.statista.com/statistics/273563/number-of-faceboo...) across world. There are more than 80+ office of Facebook world wide (source: https://www.facebook.com/careers/locations/ https://www.facebook.com/careers/locations/), so even if you distribute employee evenly on all places - you will have approx 300 employees - each location. My point is, if you were working in a company where 100 developers are creating product, than you were either at wrong place or judging the company wrong - one of them has to be true based on my research and opinion. I do not want to offend any one with my post, I am just pointing the fact based on my research, please leave a reply, If my research above is wrong or misleading.
