Our take
Zipline is reinventing how the world moves goods - one flight at a time. What started as a bold idea to deliver life-saving medical supplies by drones has grown into the world's first logistics network designed to serve everyone, everywhere. From rushing blood and vaccines to remote clinics, to dropping off everyday essential for Walmart customers, Ziplines's autonomous drones are proving that fast, reliable delivery doesn't have to be limited by roads or geography.
Zipline has an edge over potential future competitors as the company has thousands of hours and over 35 million miles of flight to prove the system is safe and effective. It’s also one of the first companies to receive a full commercial operating certificate, putting Zipline in a strong position to continuously branch out to other markets.
The unicorn company operates globally and has signed its first government contract with Rwanda to provide up to 2 million drone deliveries by 2029. Beyond government partnerships, Zipline has its sight set on everyday consumers, preparing to launch commercial deliveries straight to individuals houses. With its Walmart collaboration expanding and even Chipotle orders taking to the skies in Texas, Zipline isn't just redefining delivery - it's aiming to reach every corner of commerce, with a future that looks as bright as its ambitions.
