Bluelife has developed a system that measures nocturnal erections – a biological phenomenon that, according to Bendlin, provides one of the most objective forms of biofeedback from the male body. Unlike when awake, neither stress, performance pressure, nor fear of failure play a role here, he explains. Daniel Bendlin, co-founder of Bluelife in Videocast Pitch & People:

"These nocturnal erections are not influenced by anything. That is precisely why they are suitable for distinguishing whether erection problems have psychological or organic causes."
The system consists of three components:
- A textile cuff that is worn overnight.
- A small control unit with battery and Bluetooth
- An app
Data is collected on minimal changes in circumference – measured via inductive resistance measurement – and evaluated the following morning.
Three to five erections per night – or not.
Healthy men typically experience three to five erections per night, lasting between five and 40 minutes. If these erections are absent or significantly weaker, it could indicate an underlying medical problem.
And this is precisely where it becomes medically relevant: Erectile problems are considered an early marker for cardiovascular disease. According to Bendlin, studies show that many men experienced initial erectile problems four to six years before a heart attack or stroke – unnoticed or ignored.
Bluelife will not analyze this connection retrospectively, but will use it preventively.
Men don't go to the doctor and pay a high price for it.
A key problem: Men avoid preventative medical care. While women internalize regular doctor visits from an early age, men often keep their problems a secret for years. Instead, they consult "Dr. Google" and frequently resort to dubious solutions that mask symptoms but don't address the underlying causes. Bendlin adds:
"The men who come to us are usually already one step ahead: They want clarity. They want to know if their body is functioning properly or if they need to take action."
From sheet of paper to certified medical device
The idea for Bluelife originated with two chief urologists, co-founders of the startup. What began as a casual vision developed over seven years. to a certified medical device.
The biggest problem is the regulatory requirements. Startups are subject to the exact same rules as corporations – with corresponding time and expense. According to Bendlin, many good ideas fail precisely because of this hurdle.
Bluelife persevered. Completely self-financed, with a seven-figure sum from its own funds and without external pressure to enter the market early.
Long cycling sessions lead to weaker erections.
Today, Bluelife has already collected around five million data points – a data foundation that was previously unavailable. Initial analyses show clear correlations between erection patterns and factors such as age, weight, stress, sleep quality, and exercise.
The Bluelife data also reveals effects that may surprise many. For example, the effects of intensive cycling are clearly visible in the measurements. Men who cycle for several hours at a time sometimes experience significantly weaker nocturnal erections the following night. According to Bendlin, the effect is temporary and evens out, but it is nevertheless medically measurable. Stress and lack of sleep, on the other hand, have a particularly pronounced effect: those who sleep poorly or are under high stress experience less pronounced nocturnal erections. The data shows that the body doesn't forget anything, even during sleep.
Why Bluelife also appeals to women
As big as the problem is, addressing it remains difficult. You can't run traditional advertising campaigns about erectile dysfunction. The solution comes from an unexpected direction: women.
Because they notice the changes in the partnership, they worry – not just about the relationship, but about their partner's health. Increasingly, it is women who initiate action. A system designed for men, explains Bendlin, that is supported by women.
One less taboo, one more early warning system
Bluelife doesn't measure performance. It measures health. And it brings to light a topic that many would rather ignore – with the potential to detect serious illnesses early.
Perhaps that's precisely the startup's greatest strength: it doesn't force men to talk. It lets their bodies do the talking. And sometimes that's enough to change or even save lives.
