About Jacob Leach
Jacob Leach, who became interim CEO of Dexcom in early 2026 after previously serving as president and COO, has been leading the company through a period of public engagement with users following reported issues with the Dexcom G7 sensor. In several interviews in June 2026, Leach discussed the formation of a Customer Advisory Council, which he said was created to provide a more direct feedback mechanism from users, caregivers, and healthcare professionals. He stated that a key takeaway from the council was that the company needed to improve communication with the community about product changes and fixes. Leach also described improvements to the G7, including a new Bluetooth antenna and adhesive enhancements, and said that accuracy complaint rates were at an "all-time low."
Leach has discussed the upcoming Dexcom G8 sensor, describing it as a new platform with a "self-calibrating" technology that uses an additional signal to adapt to the user's physiology without requiring fingerstick calibration. He stated that the G8 will be half the size of the G7 and will add multi-analyte capabilities, including the ability to monitor potassium, which he noted is a dangerous condition for which there is no at-home test. On earnings calls, Leach reported that Dexcom acquired the nutritional coaching company Nutrisense and that the company's goal is to have the first continuous glucose monitor approved for use in the inpatient hospital setting. He also stated that the company is focused on improving customer service and that the customer is the "northstar" for the company.

I ever wanted for Mitchell reporting to you live from the CES 2016 digital health summit studio. I'm here with Jake Leech, who is the senior vice president of research and development at Dexcom. So welcome to the digital health summit studio.
J
Jacob Leach0:20
Thank you, it's wonderful to be here.
L
Laura Mitchell0:22
It's great to have you. So tell us a little bit about what Dexcom is.
J
Jacob Leach0:26
Dexcom is a company that empowers people who have diabetes. What we do is we give them information that they don't normally have about their glucose. We make a product called a continuous glucose monitor. It's a unique type of glucose monitor that measures glucose continuously. You get 288 readings a day, and the important part of the information is it tells you not just what your glucose is, but it tells you where it's going, whether it's increasing or decreasing. That information is very valuable for patients. It helps you be a little bit more proactive and preventative.
L
Laura Mitchell0:57
So tell us why that's important. Why is it important to instead of just taking your glucose readings multiple times a day, why is it important to have continuous?
J
Jacob Leach1:06
The continuous reading really helps you make a better therapy decision. If your glucose is in the normal range when you take a finger stick, you don't actually know if it's rising or falling. So if your glucose is rising, you would make a different decision if you knew that information.
L
Laura Mitchell1:23
Does that affect how you eat? Does it affect how you exercise?
J
Jacob Leach1:27
Yeah, everything. One of the interesting things that continuous monitoring teaches you is it teaches you how different foods affect your body. Everybody's body is affected differently by different foods, and so the trends that you get from the Dexcom system help you understand how that food affects your body.
L
Laura Mitchell1:44
Excellent. And so you had a recent launch, I think it was just at the end of last year.
J
Jacob Leach1:48
Yes, yes, yes. We launched our Gen5, it's our fifth generation product. The key to this product is the body-worn patch, the sensor that we make that is actually measuring the glucose now communicates directly to your smartphone via Bluetooth technology.
L
Laura Mitchell2:04
So is that a way that parents can also monitor for juvenile diabetes?
J
Jacob Leach2:08
Yes, there's a feature of our product called Share. So now that the data is on the patient's smartphone, it's also uploaded to our secure cloud servers, and when it's up there, it can then be transferred to the parents. So think of a child who has diabetes, their parents can monitor them when they're away from each other. It's cool at school, on the playground, at sleepovers, anytime.
L
Laura Mitchell2:29
That's great. And I would think that the same might apply for maybe a boomer trying to help their parents.
J
Jacob Leach2:36
Absolutely. It's not just for children. We get lots of letters from patients who talk about spouses when they travel and being able to make sure it's like a safety blanket to make sure that they're going to be okay.
L
Laura Mitchell2:48
Well, that's excellent. I actually got a chance to see it, it's very cool. So tell us where we can find you online.
J
Jacob Leach2:53
Dexcom.com is our website. We're also here in the hall, Hall C, we have a booth.
L
Laura Mitchell3:01
Okay, excellent. Well, thanks so much, Jake, for visiting us here at the Digital Health Summit Studio at CES 2016. I'm Laura Mitchell.
