TANGObuilder logo

TANGObuilder

TANGObuilder automates structural engineers jobs.

Today the building design process is cumbersome and expensive. Architects submit their design to structural engineers for validation. Engineers need to design all structural elements such as walls, columns, and beams to ensure the structure will not collapse and complies with regulations. The structural engineer needs four to six weeks to generate the initial solution. The engineer will submit his proposal to the architect and then engage in an extensive back and forth discussion until they agree on a satisfying solution. TANGObuilder generates the building structural design in real-time, cutting six weeks of the overall process, and reducing material usage by 30%.

TAXA Biotechnologies

We enable cheaper, faster, and better genetic engineering of plants.…

The TAXA platform has been specifically designed to enable anyone to perform metabolic engineering of plants without stepping into a lab. We provide access to protein engineering, DNA assembly, transient experiments and stable transformation as a service. The best thing is that anything "Powered by TAXA" is designed to be free from expensive regulatory approval, meaning the products are available for sale or distribution to consumers in the United States immediately after they are developed. For a detailed list of the experiments which can be run on our platform please see the Services page. Our vision is a world where bio-engineering is as easy and commonplace as mobile application development is today. Game-changing technologies, like genetic engineering, should not be the exclusive preserve of large corporations and a wealthy elite. Democratizing the tools of creation enables anyone, anywhere, to genetically engineer plants and will unleash a wave of creativity to power an environment where ultimately what we create is limited only by our imagination. The TAXA platform is our next step in the realization of that dream We are also the team behind the first synthetic biology crowdfunding project, raising $484k on Kickstarter to make real glowing plants: www.glowingplant.com

Tab

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).
