Xellow LLC is based in San Francisco, California. It was launched in 2010 by Johnson Huynh (founder).
Over 40 million Americans move to another city every year. That's what happened to me in 2007 when I decided to move from Canada to California. When I first landed in San Francisco, I had no idea what people do here for fun. Here I am in one of the most sought after tourist destinations and bored out of my mind. So my first stop, a hotel lobby.
I asked what a tourist would enjoy in the city. What I got in return was a tourist map.

Here's the hotel, and here's all the attractions around you.

And that's when the lightbulb hit.

Create a website that pinpoints your location and shows all the attractions around you.

With the rise of smart phones, Xellow.com is better than a map? How?
You get the attraction’s info on demand including :
address, contacts, description, comments, reviews, coupons, and photos.

Xellow also allows you view all the events happening around you right now. Let’s pretend you’re in Paris with your family and you want to find some entertainment within walking distance. Food festivals? Lookout spots? Indoor skydiving? All this information is a few clicks away. You'll end up doing stuff you didn't know you liked.
