About Keller Rinaudo

Keller Rinaudo Cliffton, co-founder and CEO of Zipline, has been discussing the company's expansion and the economics of drone delivery. In December 2025, Zipline announced a $550 million partnership with the U.S. State Department to expand its delivery service across countries where it already operates. Cliffton said the U.S. was seeking new ways to engage in these countries and help save lives while accelerating local economies and benefiting the U.S. economically. He also stated that the fully burdened unit economics of Zipline's systems are falling below the cost of using cars for deliveries, a shift he described as happening "quietly" in the summer of 2026. Cliffton has emphasized that Zipline's drone is only about 15% of its autonomous delivery system, with the rest encompassing inventory management, air traffic integration, and engineering systems such as a dual flight computer failover protocol. He noted that Zipline has flown 140 million autonomous miles with zero safety incidents. Cliffton has also described the company's goal as approximating teleportation, saying that if a logistics system automated delivery and reduced the cost to near zero, it would fundamentally change how people live. He projected that Zipline expects to grow to a million deliveries a day in the next couple of years, while noting that even at that scale, the company would still serve a tiny percentage of the overall market.

Look up in the sky. It's a bird. It's a plane. Zipline. Zipline. Zipline is reimagining logistics. Completely revolutionized the African health and supply chain industry. And I'm a huge huge fan of the company. I've been following this for the last couple of years.
It's not heavy.

Keller Rinaudo0:29
When I think about what we're trying to do at Zipline, we're just trying to approximate teleportation. I grew up watching science fiction. Logistics should feel like teleportation. It should be that magical.

We fly to your home and we stop over your house. So that's the moment where we transition off the wing onto the hover props. The aircraft stays up there and then the droid comes down on a zipline and delivers what you ordered. One of the most pivotal moments in my career was when I was at SpaceX and we did the first rocket landing and the parallel that I felt here when we did that first delivery and it's an opportunity you don't really get very often in your career.

One of the hardest design challenges of the Zipping Point system was how can you reliably take things in random packages and deliver them? And now Zipline is entering an entirely new era.

Keller Rinaudo1:28
The implication of Zipline is access to everything for everyone. I'm Keller Rinaudo. I'm the CEO and co-founder of Zipline. We had this really simple, naive idea, which was that somebody is going to build that for outside the warehouse. That vision wound up being a lot more complicated than we were expecting. It also wound up being illegal for the first decade of our existence. We had to operate outside the US doing life-saving use cases before we were able to bring the technology finally and start serving Americans. I think it only really became real when we signed our first customer meeting the Minister of Health in Rwanda at the time. We were saying we'll deliver medical products to every single hospital and health facility in the country and she basically said shut up just do blood. So we actually focused the first contract we signed was for 21 hospitals to deliver just blood transfusions. And the reason this is important is that it turns out 50% of blood transfusions are going toward moms with postpartum hemorrhaging. 30% are going to our kids under the age of five. And so it's a super important product for family health. You know, when we launched in 2016, we were super naive. We really didn't know what we were doing. And in fact, for the first 9 months, we only delivered blood to one hospital as we were trying to just prove that the technology could work reliably. Seeing the first delivery happen for the first customer in a way that was like, wow, there's so much we have to figure out, but we just saved that person's life. I think that's where it felt really real and it felt like there was a moral imperative to scale this to every other human on Earth. Yeah.

Marcus1:28
Hey, my name is Marcus. I lead operations at Zipline. I didn't know what Zipline or who Zipline was at all. I had no idea. Once I like got to know the company, once I got to know the tech, I immediately realized I have to work at this place. Yeah. Here, let's go over here. I'll show you there. The whole point of the aircraft is that we take off vertically, then we can what we call transition into fixed wing flight. And then we fly only on the wing. It's actually really cool. So the propellers that are on the hover motors, we turn them into the direction of the aircraft flying. And if you can imagine, so these here, these are the hover props. They will align with the aircraft in a straight line. And then this motor will tilt up and this is the only thing that powers the aircraft in fixed wing flight. Platform one is a fixed wing aircraft only. Platform one delivers in a way that we parachute it out that then with the wind drifts to where it needs to be. Though we got really good at projecting where that goes, it still is not precise enough for what we need in more dense urban areas. So the whole point of platform 2 is that there's the droid, the secondary aircraft inside the main aircraft. So this thing stops midair. We launch from our site with something loaded in it. We fly to your home and we stop over your house. So that's the moment where we transition off the wing onto the hover props. The aircraft stays up there and then the droid comes down on a zipline and delivers what you ordered.

I'm Kyle Monia. I've been at Zipline for 2 years now. I lead our application and enterprise software organization. I was at SpaceX before this and so I knew I needed a mission that really resonated with me for me to make any kind of switch. And when I saw that Zipline was now on the brink of launching platform 2 in the US to be able to go globally, be able to enable delivery of whatever you need whenever you need it, could we do it? I knew all the systems that I had been building, it's something that could really help Zipline.

Slo I'm on the new products team.
G
Gregor4:48
I'm Gregor. I do industrial design. With our precision delivery platform, right? That has this pod that comes out of the ground and the drone that stays way up high. We nailed the delivery half of that product and we needed to find a way to delete the construction project, delete the permitting, delete the space required that eliminated a whole bunch of sites where we wanted to be able to deliver from the zipping point was an answer to that question of how can we not require any space or construction and enable anybody to deliver with the system.
Z
Zipline Employee5:15
I like the latch and handle on the front of the droid, right? Like you need a handle that's comfortable to use. You also don't want this to become undone during flight. And you also want it that if I click this, it clicks both sides. We have actually redundant latches here. The two of them act independently, but the design is such that they both act at once, and we actually sense that it's closed.
K
Keller Rinaudo5:36
Platform 2 is designed for home delivery. And a home delivery opens up a whole bunch of new significant technological challenges. Not only do we have to fly in 100% of weather, but we need a system that can hover when it's docking, as well as when it's delivering. We need a system that can deliver in a super super accurate way. We typically want to be able to deliver with like dinner plate level accuracy to somebody's home. Additionally, we need it to be incredibly quiet cuz we're now flying in like really really busy neighborhoods where we want to be quieter than a car delivering a similar package. Package delivery in the US is one of the most competitive markets on Earth. It's not like you get to build a product that is super duper expensive that customers are willing to pay, you know, $100 a delivery for and you're actually competing against cars and human beings and systems that are at massive scale. Platform 2 had to find its way to this intersection of like product experience, safety, unit economics. If the internet automated moving information around and reduced the cost to zero, what would it mean if a logistics system automated delivery and reduced the cost to near zero, you fundamentally change the way that you live your life. And in fact, that's what we're seeing with so many of these customers in Dallas where it's like reconfiguring how they think about ordering, how they think about grocery shopping, how they think about food and cooking at home, how they think about how they get their prescription or how they engage with a healthcare system. All these things are going to change if you actually build autonomous delivery.
Z
Zipline Employee6:55
The zips themselves fly completely autonomous. So, they will go, they will sense if there's anything that may be an issue. They'll know to go back and dock themselves. They'll know if they need to abort the missions. They figure all of that out on their own. And that's really what you want, right? We want that real-time sensing. We do have flight operations who are there to just ensure that there are no issues that come up that are surprises because safety is so important to us that we need to just make sure that there is something and the flight controllers, they can go and say, 'Oh, I see some aircraft is doing something strange in this area. I'm not really sure what it is. Tell the zip to go dock.' One of the reasons we're able to do this so quickly, is because we built a great partnership with the FAA where we make sure the systems that are in the loop, especially with with no humans, those are incredibly safe. We know how to iterate that really quickly and being able to make sure the FAA is comfortable with that. Also, for engineers, we make sure they really have this extreme ownership where they can see a problem and solve that problem.
My favorite way to think about it is I'm always picturing this thing delivering in my backyard with my kids playing. We have a lot of rigorous things we do to say we're ready from a safety perspective. In particular teams that analyze the data and look at all these systems. So like nothing hits through the cracks. If someone's worried about something, we get all over it. We go we go improve that that reliability to keep pushing that bar up.
This is our hardware in the loop lab where we have our drones fully assembled minus the body parts. Reliability or safety is like a Swiss cheese. Each layer of safety or reliability and something will only fail if all the holes in the cheese line up. We have a layer in software development. Continuous improvement layer, software in the loop, hot wind loop, the reliability in the loop. Then we have a test layer, the test sites that at the test sites we have multiple layers in there where on purpose we try to make the aircraft do something it shouldn't be doing and we see how the aircraft behaves. We know early in the development phase and we don't find out in commercial operations.
There's no packaging requirement. That little pod could come down and deliver something in no packaging whatsoever, which is obviously another part of the future we want to live in is a packaging free future. One of the hardest design challenges of the zipping point system was how can you reliably take things in random packages and deliver them? And I love these examples. So Gregoire has got a blueberry, you can deliver a tray of cups, you can deliver random food packaging, whatever you've got, and then will reliably transfer it into the pot.
If we can pick up a blueberry without crushing it, we are golden. Like we we can probably deliver anything. What started as a joke was like, wow, actually we can. Yes, we can.

Keller Rinaudo9:26
So, recently we hit 2 million flights. The amount that we've accomplished in 2 years is amazing. And I think it speaks to what an amazing company that Zipline is and the people who we have working here who are so empowered to be able to solve problems and get through first principles engineering. Like what do what problems do we need to solve? How do we keep building? How do we keep learning? We ultimately over the next couple years expect to grow to a million deliveries a day. That's kind of like the next thing that we're targeting. But at a million deliveries a day, you're still only serving a tiny percentage of the overall market. When you have a system that customers can just get things delivered in just a matter of minutes and it's very, very affordable and it's safe and it's predictable, customers consume a lot more of that service. We actually see a lot of customers throughout Dallas are ordering every single day from Zipline. The big realization is man there are 5 and a half billion instant deliveries happening in the US every year right now just you know traditional delivery platforms and if you were to extend the customer behavior that we're observing in Dallas right now to the rest of the US there would be 50 billion instant deliveries happening the only way we're going to get that kind of scale and that kind of efficiency is through AI and robotics but the good news is those kinds of services are not just going to save hundreds of thousands or millions of lives. You're also going to save people huge amounts of time. You're going to save people money, give people time back to spend with their families, their loved ones, do the things that really matter in life as opposed to being like stuck in traffic or walking back and forth in stores.
For any problem or in any industry in the world, there are like a thousand reasons something will not work and a thousand reasons to not even try. In fact, the more you're an expert in the thing, the better you understand all the reasons that the thing won't work. You have to both be naive because you have to have a poor understanding of all the reasons a thing won't work because those things will discourage you from doing it. You also have to be contrarian enough that you'll ignore all the experts who tell you you're a complete idiot and you're wasting your time and you shouldn't try. So I think you know the more important the problem, the more experts will tell you with complete conviction that you are going down the wrong path and it will not work for all these different reasons, whatever it is. Zipline was a pretty big vision. This idea of building an automated logistics system for Earth that would serve all people equally. There were a thousand reasons it wouldn't work. We kind of had to be willing to to some degree we had to be naive of all the things that were hard about it that wound up being really hard. And we also had to be contrarian enough to ignore all the global experts who were telling us we shouldn't even try. And what's really been exciting is this last year we were looking really at the the zero to one, right? Like can we make this happen? We had so much customer demand when we actually went we knew like we had something. So now looking at this next year we're going from one to thousands, right? Like orders of magnitude jump. We're now thinking about how do we change our systems to not just be the scrappy things you experiment at the beginning but systems that can actually scale.
Z
Zipline Employee12:07
One thing I always say is that if you join the company and you come with a idea in your field of expertise it will probably have an 80% improvement somewhere in the company and that is not because we're we don't know what we're doing. That is because we're so early in our scale phase as we're prepared for the hypers scale that is starting like next year. That is what makes the pace happen.
K
Keller Rinaudo12:26
This has always been our culture. I think as the company grows, our objective is to like you try to avoid the bureaucracy. You avoid the consensus decision-making. You avoid the kind of like risk off legalistic posture of like let's just make sure we don't screw up. It's like that's not the goal. The goal is to build products that are extraordinary and that requires risk. It requires failure. You have to believe in people who are early in their careers. You have to give irresponsible levels of responsibility to a lot of different teams and then trust them to keep trying until they ultimately build something great. Crazy is that over nine years of partnering with the government going from that very first contract just serving one hospital we've now expanded to 50 then to 100 then a thousand today's zipline serves almost 5,000 hospitals and health facilities day in and day out 24/7 365 we also just announced our new national scale partnership in Rwanda not only do we now serve every hospital and primary care facility in the country and we deliver every essentially the entire medical public healthcare supply chain is delivered autonomously We're also now adding many new use cases and we're bringing platform 2, the next generation technology to Rwanda for the first time. So 9 years in and the partnership is still growing exponentially fast, adding new use cases and essentially just becoming national scale infrastructure in today's age now where AI is just improving more and more. We're bringing AI more into developer workflows, into our products to be able to really just move so much faster and really like solve these problems so much faster. And so I say it it is so exciting where we are now because I think these next few years are going to be they're going to be pretty crazy and I'm actually not sure what to expect. But being able to bring all of that to Zipline and for what we can enable here, I think that's a future I'm really excited for.

Host14:12
We have been trying to make this episode on Zipline for 3 years. Ever since I started out S3, when it was just me and a camera going around filming people, I was emailing Denton from Zipline saying that we wanted to have them on the show. And every quarter he would say next quarter, next quarter, next quarter. And I kind of thought it was just like a no, we don't want to do it, pushing us off. But really, it's cuz they wanted to get their their V2 platform ready to show off. And in that time, they were in the middle of testing. And now after 3 years of waiting, we finally got to feature them. What was what was it like for you guys? Follow me up.
R
Reporter14:40
It was so inspiring. I mean, I had like a very special relationship to covering this company. I had pitched and written a story about them nine years ago when I was an intern at Business Insider. And um at that time I remember thinking like, 'Wow, this is such a cool company. It's so sci-fi feel.' And now that we actually got to visit them and see what they're doing and bringing it to the US is pretty epic.
H
Host15:00
Zipline is is in a unique situation where they are a startup building a very novel technology, a UAV delivery drone that's never been done before, but they're doing it in a very heavily regulated safe environment of aviation of traditional aerospace.
R
Reporter15:13
Cuz they're still regulated by the FA. Right. Exactly. Like like when I walked realized, oh, each of their drones has a unique tail number. I realized, wow, each of these drones is a unique registered aircraft with the FAA. This isn't just some rogue thing.
H
Host15:23
But it's getting beyond visual line of sight is like pretty hard cuz for context, you're a pilot. You fly for real, right? And like like BV loss is not like a easy thing for a company or an autonomous company to get. Right.
R
Reporter15:33
Exactly. And that's a completely novel thing that FA is trying to figure out. And Zipline is like in that process of like figuring out what does that actually look like in the regulations.
H
Host15:39
Yeah. I'm not aware of anyone else that's actually delivering real customers in Texas with active systems doing BV loss operations the way that is up by
R
Reporter15:46
Exactly. Which is nuts.
H
Host15:47
And it is amazing they've been able to do that while still maintain this incredible safety record while also maintaining like incredible levels of innovation and speed. Yeah.
R
Reporter15:55
Um, they're so effective at their size. That's what's so shocking. Exactly.
H
Host15:59
I felt that they all carried this early startup mentality which is like we're going to continue to take risks. were going to continue to like operate and give irresponsible levels of responsibility to all of their employees.
R
Reporter16:12
Yeah. Like that just doesn't feel like a thousand person like dude dude in his laptop like looking at like debugging a thing just feels startupy versus like the stove of company that they are.
H
Host16:21
Exactly. If you had to take one thing that you learned from making this episode, what do you think that it was?
R
Reporter16:25
They keep this idea of wanting what they're creating to feel like magical and like sci-fi. They want logistics to feel like teleportation. When you're founding something, it's very easy after three, four, five, six, seven, eight years to start trailing off and almost like soft retiring. But I did not get that sense from the co-founders at all. They seem more locked in and and refreshed than ever, which is I think it's hard to do. What Zipline originally started was not the drone delivery company they are today. Yeah.
H
Host16:53
They started with this crazy vision of wanting to provide medical care and medical supplies to these very remote rural areas.
R
Reporter16:59
Yeah. Um, and the beautiful thing is that they've done that and they realized, oh, the technology we have goes way beyond just this one application. They took that technology and they the vision that they have with that and they let it grow into this massive thing they now have here in the US with this with this drone delivery while simultaneously still also doing this whole medical vision in Africa like this they're they're maintaining all those things but they're they're not limiting themselves with this technology like there's so many different areas
H
Host17:22
and they're still operating in Rwanda in that entire area right which is nuts like that's not easy to do
R
Reporter17:26
and both like the the US operations and Rwanda uh operations are feeding off each other with the technology and the things they're learning where it's like this crazy flywheel of um of innovation it's really amazing And all that, I think, put together is what made Zeline such an awesome feature on this episode of S3.
H
Host17:40
Hi, Will.
W
Will17:40
Hi, I'm Will, head of finance here at Story. S3 is an incredible but expensive show to produce. And that's why we'd like to thank today's sponsor, Senut Send.
So, if you're building physical stuff with metal in it, and you want your parts shipped quickly and made in America, that is where Senut Send comes into the picture.
H
Host17:56
It's surreal to have Senut Send sponsoring S3 because almost every company we feature on the show uses Suncut send. Whenever we go and film there, we see sheet metal parts that they produce, CNC parts, and the wrapping papers with Sen Cuts Sense's logo all over the floor.
And if you're building crazy projects and things like Zipline is, and you need good high-quality metal parts, reach out to Senuten and tell them he sent you.
Thank you for watching this episode of S3. And as always, until next time, keep on building the future.
