Beta Bionics Does the Work to Reduce Insulin Pump Burden
20 Nov 2025
“In the case of iLet, we're going to say, this is how much insulin they're getting for what they consider to be a usual meal. And we learn that and we can set it that way. So we just take the responsibility of learning carb counting, which is really tough, off the user's plate. That's an extra level of automation that traditional pumps don't provide,” Beta Bionics CEO Sean Saint explains to Bloomberg Intelligence. In this episode of Vanguards of Health Care, Saint sits down with BI analyst Matt Henriksson for an in-depth interview about Beta’s iLet pump, designed to eliminate the human stress of making insulin dosing decisions. The conversation also touches on the company’s pay as you go strategy through the pharmacy channel and future product development, including the Mint patch pump.See omnystudio.com/listener for privacy information.

Welcome to another episode of the Vanguards of Healthcare series. My name is Matt Henriksen, the Medical Technology Analyst at Bloomberg Intelligence, which is the in-house equity research platform of Bloomberg LP.
We are pleased to have with us today Sean Saint, CEO of Beta Bionics, a medical device company that is a key leader in the expansion of automated insulin delivery systems, or AIDs for short, the next generation of insulin pumps to help diabetic patients keep track of their glucose levels. You can dive deeper into the financials by typing in BBNX Equity Go on your Bloomberg terminal.
Sean, thank you for joining us today. Thanks for having us, Matt. And Sean, you know, you started the role of Beta Bionic CEO a few years ago, but what You've had a long history in the diabetes space, at a personal level as well. So why don't we start with, for the listeners, a story of your path that got you to the CEO role today?
Ooh, yeah, long and winding road, actually. Matt, I got involved in diabetes, gosh, over 20 years ago now with a little company you may have heard of called Dexcom. Obviously, they're not a little company anymore, but at the time, they really were.
We didn't have real-time continuous glucose monitoring at that stage, and looking back on it 22 years later, we had no idea what it was ultimately going to become. But yeah, I spent about five years there. Later moved on to tandem diabetes care, designing insulin pumps. And it was oddly a tandem that I got diagnosed with type 1 diabetes myself.

Chapter 2: What is the main purpose of the iLet insulin pump?
But walk us through, for these patients who need insulin, what were the steps that they had beforehand and then kind of has progressed to now what we're calling, you know, the AIDs?
Wow, that's a far-reaching question. Let's start at the beginning and say that people with type 1 diabetes, and certainly type 2 is similar in the way it's treated. The physiology is a little different, but let's talk about type 1 for a second. Your body stops producing insulin. Obviously, it's usually done in the pancreas. There's various cells in the pancreas that in effect are killed off.
It's an autoimmune disease, and you need to replace that insulin. You need to do it on a daily basis or you're going to be in big trouble. So historically, patients have had to take insulin multiple times a day, either through what we call multiple daily injections, shots, or through an insulin pump. Now, of course, we've been doing shots since 1921, I think insulin was first formulated.
Pumps, of course, are more recent. They came about in the 80s. And the reason for pumps at that time is that insulin itself was really not great. It took a long time to act. It was not flat in the way it acted on your blood sugar.
And what we realized is that if you give a little bit of these comparatively poor insulins every five minutes, it flattens out their response and makes them nice and predictable. And that was the original benefit of an insulin pump, again in the 80s. You get into the 2000s and we've got better insulins that are really flat by their very nature.
And interestingly, during the 2000s, we struggled as an industry to see if there was a clinical benefit of insulin pumping fundamentally. The trials at that time were not really showing that. you could do just as well with multiple daily injections as you could with an insulin pump.
What was beginning to be a benefit at that time was CGM, continuous glucose monitoring, that really became a patient-centric tool in 2006 with Dexcom. And that was the first time that a patient could really react to their blood sugar in quite a bit more rapid way. Rather than three to five to 10 blood sugar measurements a day, you get one every five minutes for 288 points per day.
What that led to, though, was the combination of continuous glucose monitoring and insulin pumps, which allowed us to put algorithms on top of that to close the loop and respond to your blood sugar in real time. And that was the advent of automated insulin delivery technologies. They really started in the early 2010s and done nothing but gotten better to where we are today.
And of course, Betabionics represents the most recent and sort of the highest level of automation of what that is.

Chapter 3: How does Sean Saint's personal journey influence his role at Beta Bionics?
How is that designed to kind of, you know, have that dual mandate of one accuracy and being able to deliver the right insulin at the right time, but also that ease of use factor?
Yeah, so I would say there are two concepts that we want to keep in mind in order to understand that question. The first is the way the user experiences the pump, right?
the sorts of interactions they need to have with it, how often they need to announce a meal, do they need to count their carbohydrates that they're eating, do they need to deliver correction boluses of insulin, do they need to extend their boluses of insulin, all these complicated concepts that with a traditional automated insulin delivery system they need to do.
And beta bionics is designed to eliminate most of those things. We ask you to tell us that you're eating, but we don't require that you count carbs. We don't require that you ever give a correction bolus. Any of those other things I stated, not necessary with the islet. So we're reducing the burden and the engagement required to really get a great outcome with our product.
And then sort of orthogonal to that is the burden on the healthcare provider. Traditional automated insulin delivery systems require that the physician, Get an idea of who you are. They're going to start with your weight. They're going to not guess, but rule of thumb, your insulin sensitivity and your carb factor and all these variables that we have with how your body works.
and they're gonna enter those into the pump. Our product starts with your weight, and again, because these are rules of thumb, we can use that weight, and then we learn and adapt to you automatically.
So rather than going back to your doctor every three months to have them read your glucose charts and try and guess at how your variables are different than what's currently programmed into the pump, we're gonna do that on our own, usually within a few days. It just removes the burden of the healthcare provider and really ensures that that pump worked perfectly for you
The whole time, which also is an interesting benefit, opening up the technology to health care providers that don't necessarily have the skill sets to manage an insulin pump. And of course, I'm talking about primary care physicians here who manage, frankly, most of the patients with both type one as well as type two diabetes.
Interesting. And I was about to ask, kind of dive in a little bit deeper into that carb counting, because that is an important input for some of these other pumps. I was going to ask how your algorithm is able to avoid requiring those carb counting. But it sounds like it takes, it's a few days of learning the patient's behavior.
