Blood products, with their short shelf life and critical role in emergency care, present a formidable logistical challenge in remote regions. For Zipline, a commercial drone delivery company founded a decade ago, this challenge became the foundation of a transformative mission. From its base in South San Francisco, the firm has built a network capable of transporting vital medical supplies across Africa, the United States, and beyond. Its recent milestone—the 1 millionth commercial drone delivery—was marked by the transport of two bags of IV fluid from a distribution center in Ghana to a local health facility.
The company’s origins trace back to a period of intense field research. Co-founder and CTO Keenan Wyrobek emphasized the human-centered approach that guided their early work: “If you want to create technology that’s going to fundamentally impact people, you don’t start with technology at all. You have to start with people.” Over two years, the team mapped areas of greatest need, studied healthcare supply chains, and engaged directly with doctors and patients.
A pivotal moment came during a conversation with a public health graduate student in Tanzania. The student had persuaded doctors to text him whenever they lacked the resources to treat a patient, recording the outcomes in a spreadsheet. When sorted, the most frequent result was death. Wyrobek recalled, “It was one of those moments where we realized, if we had drones and people could text us, we could just send them whatever they needed. That stuck with us.”
Finding no suitable off-the-shelf aircraft, Zipline embarked on designing its own drone—waterproof, tailored for medical payloads, and assembled and tested in the United States. Eighteen months later, the company launched its first operational service in Rwanda, delivering blood to hospitals. Partnering with an expert in blood handling, they recruited hundreds of graduate students to donate blood for research into delivery effectiveness. The success of these missions quickly led to requests for vaccines, pharmaceuticals, and other critical supplies.
Within two years of signing its first agreement with the Rwandan government, Zipline expanded to a second distribution center, extending service to smaller health facilities. Four additional centers followed, enabling nationwide coverage. The company then moved into Ghana and now operates in five African countries.
In 2021, Zipline’s U.S. operations gained momentum. Initially delivering personal protective equipment, the company began transporting pharmaceuticals and consumer goods for a Walmart in Pea Ridge, Arkansas, near the retailer’s headquarters. Expansion to Dallas followed. In 2022, deliveries commenced for Intermountain Health in Utah.
Engineering advancements continued with the development of a second drone platform in 2023, designed for shorter distances and direct-to-home service. This platform supports Zipline’s growing work with restaurants and retailers, broadening its customer base beyond healthcare. Contracts now include more than 20 U.S. organizations such as Cleveland Clinic, GNC, Sweetgreen, Panera, and MultiCare Health System.
Wyrobek noted the operational efficiencies gained through scale: “As we build more drones, it improves volume, while driving costs down.” The company’s reach has extended to collaborations with the U.K.’s National Health Service and entry into Japan in 2022.
Cost reductions have been significant. Wyrobek stated that some companies have cut expenses by half. A 2022 study in The Lancet reported that hospitals reduced blood supply waste by 67% through Zipline’s delivery model. These figures underscore the engineering and logistical precision underpinning each flight, from aerodynamic design and payload security to route optimization and regulatory compliance.
For engineers and technologists, Zipline’s trajectory illustrates the integration of aerospace design, robotics, and supply chain innovation into a cohesive system. The drones themselves must balance range, payload capacity, and environmental resilience, while the distribution centers act as high-throughput nodes in a responsive network. The result is a scalable infrastructure capable of delivering life-saving materials in minutes, reshaping expectations for unmanned aerial logistics.
