In this episode of Acquired, featuring Ben Gilbert and David Rosenthal, Novo Nordisk (Ozempic) explores novo Nordisk’s century journey from insulin to Ozempic dominance The episode traces Novo Nordisk from insulin’s 1920s origins through a decades-long Danish rivalry (Nordisk vs. Novo) that accelerated innovation in insulin purification, duration, and delivery.
Novo Nordisk’s century journey from insulin to Ozempic dominance
The episode traces Novo Nordisk from insulin’s 1920s origins through a decades-long Danish rivalry (Nordisk vs. Novo) that accelerated innovation in insulin purification, duration, and delivery.
Novo’s unusual governance—control by a charitable foundation—shaped strategy, long time horizons, and even blocked a 2004 sale that likely would have prevented Novo from capturing the GLP-1 wave.
It explains the scientific and commercial path from early GLP-1 research (1990s) to liraglutide (Victoza/Saxenda) and then semaglutide (Ozempic/Wegovy), which crossed the “~10% weight loss” efficacy threshold and triggered explosive demand.
The hosts also unpack why US drug pricing/coverage is uniquely complex (PBMs, rebates, Medicare rules), why insulin economics deteriorated, and why GLP-1s could become a new multi-decade pharma super-cycle with broader indications (cardio, kidney, Alzheimer’s).
Key Takeaways
Novo’s edge is extreme focus compounded over a century.
Novo Nordisk stayed heavily concentrated in metabolic health rather than diversifying like most pharma. ...

Foundation control materially changed the company’s destiny.
The foundation’s voting control (majority votes, minority economics) reduced short-term market pressure and blocked a 2004 merger. ...

Competition “down the street” created durable innovation momentum.
Novo and Nordisk’s bitter rivalry forced rapid iteration: shelf-stable liquid insulin, longer-acting formulations (e. ...

Biotech scaling (Genentech) transformed insulin from scarce to mass-market.
Animal-sourced insulin was supply constrained, limiting Type 2 insulin use historically. ...

GLP-1 success required solving half-life and adherence, not just biology.
Native GLP-1 degrades in minutes, so Novo’s key breakthrough was engineering longevity (fatty-acid/albumin binding in liraglutide; even longer duration in semaglutide enabling weekly dosing). ...

Semaglutide crossed the ‘activation energy’ for obesity drugs.
Past weight-loss drugs were unsafe/ineffective and heavily stigmatized; an ~8% weight loss (Saxenda) was meaningful but didn’t transform the market. ...

US coverage incentives, not science, may be the biggest adoption limiter.
Private insurers’ short time horizons (job churn) reduce willingness to pay for long-term preventive benefits, while Medicare Part D is legally barred from covering weight-loss drugs. ...

If Medicare Part D were changed to cover anti-obesity drugs, what guardrails (eligibility, duration, outcomes-based contracts) would actually control total spend?
It explains the scientific and commercial path from early GLP-1 research (1990s) to liraglutide (Victoza/Saxenda) and then semaglutide (Ozempic/Wegovy), which crossed the “~10% weight loss” efficacy threshold and triggered explosive demand.

Do GLP-1 discontinuation rates (roll-off after ~1 year) mainly reflect side effects, cost/coverage churn, or unrealistic expectations—and what would improve adherence?
The hosts also unpack why US drug pricing/coverage is uniquely complex (PBMs, rebates, Medicare rules), why insulin economics deteriorated, and why GLP-1s could become a new multi-decade pharma super-cycle with broader indications (cardio, kidney, Alzheimer’s).

All right, first episode back. Let's see if I can do this sleep-deprived. [laughing]
[laughing] Oh, you and me both, Ben. [laughing] Oh.
Who got the truth? Is it you, is it you, is it you? Who got the truth now? Hmm. Is it you, is it you, is it you? Sit me down, say it straight, another story on the way. Who got the truth?
Welcome to Season Fourteen, Episode One of Acquired, the podcast about great companies and the stories and playbooks behind them. I'm Ben Gilbert.
I'm David Rosenthal.
And we are your hosts. Today's episode is on the company behind the sensational diabetes and weight loss drugs, Ozempic and Wegovy. The company is Novo Nordisk. Now, when I first learned about Ozempic a few years ago, I thought, "Of course, this is gonna be amazing for a lot of people and could also completely destroy the market for insulin. Those insulin companies better watch out." But here is the fascinating thing, listeners: Novo Nordisk is the company behind insulin, or at least one of the few big ones. Now, you might say, "Well, that's okay, 'cause they're probably a big pharmaceutical company that's, you know, very diversified with lots of different drugs."
Nope.
No. Novo Nordisk is unique in that the vast majority of their revenue is concentrated in the category of metabolic health. They have been the insulin and diabetes company for the last one hundred years, and perhaps even more surprising, this pharma giant is unique in that they are owned and controlled by a non-profit foundation. The stats around weight, diabetes, and its impact on our society are staggering. There are thirty-eight million Americans with diabetes. That's one in ten people. Globally, that number is over five hundred million with the disease. Diabetes costs the US alone more than three hundred and twenty-seven billion dollars a year, and on the other side of things, in the weight category, around a billion people suffer from obesity worldwide. A billion, including forty percent of the US population. If you expand that from obesity to overweight, seventy-five percent of Americans are technically overweight. It is really hard to imagine a bigger market to go after, which is why Novo Nordisk has become Europe's largest company, surpassing even LVMH last year, David.
Yeah, it's wild. I mean, there are no other disease and drug categories besides diabetes and obesity, that this could be possible to have a company of this size, to have a pharma giant pretty much just focused on this one area. Like, this is the Hermès of the pharma industry.
Yeah. So why is today, in the early twenty twenties, the moment in human history for these new GLP-1 drugs? The crazy thing is, semaglutide, the molecule in Ozempic and Wegovy, was pioneered back by Novo Nordisk with the first trial in 2008 for Type 2 diabetes treatment, and it was built on research started in the early nineties. But here we are in 2023, almost three decades later, talking about it as a weight loss drug that sort of magically appeared out of nowhere, or that's at least the public perception of it. Incredibly, the fact that GLP-1 drugs could be used to reduce food intake was actually discovered way back in the mid-nineties, in the first sort of scientific publication about it, but only in 2021 did we finish the clinical trials that truly show how effective it can be.
