Zipline was founded to create the first logistics system that serves all humans equally. We design, manufacture and operate the world’s largest instant logistics and delivery system that is used by businesses, governments and consumers. Zipline is transforming the way goods move, from powering Rwanda’s national blood delivery network and Ghana’s COVID-19 vaccine distribution, to providing on-demand home delivery for e-commerce, to enabling healthcare providers to bring care directly to U.S. homes. The technology is complex, and includes autonomous, electric drones, but the idea is simple: a teleportation service that delivers what you need, when you need it. By transitioning to clean, electric, instant logistics, we can decarbonize delivery, decrease road congestion, and reduce fossil fuel consumption and air pollution, while providing equitable access for billions of people. Zipline operates on three continents (North America, Africa and Asia) and in seven countries - Rwanda, Ghana, the U.S., Nigeria, Japan, Kenya and Côte D’Ivoire. Zipline has made more than 540,000 deliveries to real customers, and currently completes one every 90 seconds. Zipline has flown 40 million autonomous commercial miles, delivered almost 5 million products (including more than 8 million vaccine doses). Zipline has two delivery platforms - a long-range system, Platform 1, and its next-generation home delivery system, Platform 2. Our drones are what people see, but they are only a small percentage of what we do. Behind each delivery is a complex network of airspace deconfliction tools, inventory management, fulfillment software, warehousing, performance management, cold chain storage, and more. Zipline’s instant logistics system is a trusted partner for businesses, governments and consumers, and currently supports the medical, health and retail sectors, delivering blood, vaccines, COVID supplies, prescriptions, e-commerce items, products that support human and animal health, and food.

For many organizations, the most valuable asset is their data. Whether source code, product designs, customer records, financial results, or pricing models, every organization has information they don’t want to get in the hands of competitors, sold on darknet marketplaces, or exposed publicly. Keeping that data safe has been a challenge, until now. Cyberhaven gives organizations the tools to safeguard their data from theft or misuse. In the process, we’ve become the standard for Data Detection and Response (DDR), the category we helped create.
