Airbnb

YCombinator

Book accommodations around the world.

Founded in August of 2008 and based in San Francisco, California, Airbnb is a trusted community marketplace for people to list, discover, and book unique accommodations around the world — online or from a mobile phone. Whether an apartment for a night, a castle for a week, or a villa for a month, Airbnb connects people to unique travel experiences, at any price point, in more than 33,000 cities and 192 countries. And with world-class customer service and a growing community of users, Airbnb is the easiest way for people to monetize their extra space and showcase it to an audience of millions. No global movement springs from individuals. It takes an entire team united behind something big. Together, we work hard, we laugh a lot, we brainstorm nonstop, we use hundreds of Post-Its a week, and we give the best high-fives in town. Headquartered in San Francisco, we have satellite offices in Dublin, London, Barcelona, Paris, Milan, Copenhagen, Berlin, Moscow, São Paolo, Sydney, and Singapore.

Shred Video builds automated video & photo systems that allow…

Shred Video, a new startup launching out of Y Combinator, allows users to take footage from their iPhone, GoPro or drone and simply match it with a song from the user’s iTunes library. That’s all. Shred Video does the rest of the work. Taking into account the acceleration of the camera itself, Shred Video can pin-point the moments of action for surfers, snowboarders, skaters and other acceleration-based sports to highlight all of the coolest clips in your footage. And beyond that, Shred Video matches those epic moments with the beat-drop of the song.

Revolutionising the way travellers discover, plan and book a trip

At Tab, we’re revolutionising the way travellers discover, plan and book a trip. The Guide lets travellers find and book anywhere — with helpful recommendations from friends & local experts, rather than bland listings with endless reviews. Planning your trip should be a joy, not a chore! We help people to travel responsibly, by booking direct instead of using traditional booking sites. Travellers get the best price and they help local businesses avoid unnecessary fees. Travel experts, content creators and the friends you always ask for recommendations can use The Guide to showcase their favourite places to stay and things to do. When you book one of their recommendations, you’ll get a discount from the business and they receive bonus credit to say thanks. The Tab platform gives independent tourism businesses the tools to improve their online presence, be discovered, take direct bookings — and also to take payments. Our payment platform is uniquely designed for tourism businesses, handling over 100 currencies natively, and every payment type securely and easily. As travel returns after a difficult period, it’s time for a fresh approach. That’s why we’re building a social commerce platform for tourism — helping to spread the benefits of tourism far and wide, and helping travellers make the most of their precious time abroad. We're headquartered in London, and backed by Y Combinator (the investors behind Airbnb, Dropbox and Stripe).
