We put together a map that shows where YC companies are from. It’s based on the location of the founders before applying for YC. As a founder and previous YC applicant, I know how daunting the application process can be, especially, when you are far away from San Francisco. Now that I work for YC, I wanted to help build it.
Let us know if you have any feedback
Would it be possible to break down the US startups by state? It'd be great to connect with local people, if possible.
How exactly do you collect that data?
I see at least one company which is off.
Edit: Actually it looks like you're missing all of S05.
When I click on a country in map, the text listing should show the name of the country and not just the flag. Flags are great but I would rather read "China" than seeing the flag since a lot of us may not know every flag in the world.
The top 5 are :
United States: 1062
I'm surprised India has more presence than China considering how much the news talks about places like Shenzhen.
If you can't pitch in fluent English and you can't hire someone to help you (due to the resource constraint of your early stage startup), how can you be properly evaluated by YC or other Silicon Valley VC firms?
Another possible reason may be easy to access local capital in China.
I'm sure a lot of founders are still Chinese, just that they are coming from the USA (or other countries) before applying to YC.
(Micro-nitpick: The color scale is a little bit confusing. Darker = more startups; but USA [1,062 startups] and Canada  both have #597b9f as color, even though there's a one-thousand-company difference)
I noticed an error: Flutterwave and New Incentives are supposed to be in Nigeria not Niger.
Niger is above Nigeria (the darkest country in Africa).
E.g. our company (not YC alumni) is incorporated in Delaware and based in Mountain View, but both founders are Polish and half of the employees are in Poland. On such list, we would come up as USA company. Probably quite a few companies have the same effect.
Slight nitpick - I really wish click to drag panning and mousewheel/pinch zooming was supported on the map. Navigating the map was a bit of a chore - mostly for smaller geographically sized countries.
For some reason my YC profile had a non-existent website listed (awaaz.mobi). I have changed it now to zipphone.com (not hosted, since the company was acquired), and changed the email to email@example.com.
I think the founder of Greplin/Cue was from Jerusalem
