We help get compensation for air passengers that have experienced delayed, cancelled, and overbooked flights. We make the claim process much faster, easier and less painfull because the airlines won't. We love new challenges! As a start-up, we’ve been through it all and thanks to this our AirHelpers have developed the skills to deal with it all, and more, all while remaining passionate about what we do – helping ordinary people – as flight delays can happen to anyone. What helps us continuously develop, is our combination of talent, passion and persistance. What makes us different? Every single one of our employees can make an impact on the future of AirHelp – come up with an innovative idea – and we’ll help you implement it at AirHelp. This is an experience you can gain in very few places! If you’re looking to develop new skills, make an impact on not only global business, but ordinary, everyday travellers, and take risks developing and implementing new projects – what are you waiting for? Come join us today! With a variety of departments to choose from: tech, product, legal, finance, human resources, customer service (and the list goes on!) - you don’t have to narrow your horizons, just take your pick.

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.

Nanotechnology-enabled coatings for automotive and defence sectors

Alchemy is a nanotechnology company based in Kitchener, Ontario with core operations in the automotive and defense sectors. Automotive - With the widespread adoption of ADAS systems in new vehicles, the cost of replacing a windshield in new vehicles has tripled to $1500+. We have developed a windshield protection film product line called ExoShield to help vehicle owners protect their windshields. Our ExoShield GT3 film is sold through 400+ aftermarket installers and car dealerships in 56 countries that carry and install it for vehicle owners. For Jeep Wrangler and Ford Bronco owners (google: broken windshield club), our ExoShield ULTRA DIY kits are available via our website and dropshipping partners. Defense - Over the last 3 years, we have been working with the Canadian Armed Forces to develop an infrared camouflage technology. We have received two contracts from CAF to develop our technology. Our solution has the ability to be integrated into the uniform directly (adding just 5-10g of weight vs. 600-18,000 kg of weight for other alternatives), has outperformed all existing NATO alternatives in multiple CAF field trials, and is receiving support from major elements of CAF for our next contract. This technology can also be adapted for other individual camouflage integrations (face paint and individual nettings) and for mobile camouflage applications (vehicle nettings and vehicle paints).
