Your Brain Is Complex - Here's Why

Your brain consists of networks. It creates pathways automatically, helping you function without the need to make decisions every second. These pathways are created based on the requirements of your daily life and eventually become your habits.

Your brain is a very flexible system. New pathways can be created up into old age. This amazing capability is called neuroplasticity and helps you adapt to changing requirements in your daily life. Throughout your entire life, your brain can build up new pathways and get rid of the ones you do not need anymore. By engaging in an active lifestyle, you can train your brain and improve neuroplasticity and your brain’s health.

Why Does Your Brain Need Training

Just like the muscles in your body, your brain can be trained. The more you train it, the more you can learn to control your brain activity and reach new heights in brain performance.

Neuroplasticity gives you the ability to naturally strengthen your brain. By training and strengthening your brain, you can create new pathways that allow for more mental flexibility and higher function.

With Mendi, advanced sensors measure your brain activity. Your brain activity is then visualized in a fun and easy to use training app. By training with Mendi, you effectively train the Prefrontal Cortex (PFC) area of your brain, which directs your brain’s pathways.

CEOs, Artists, Athletes and NASA pilots have been using brain enhancement training to improve health and cognitive abilities for years. The fundamental skill that separates top performers from ordinary people is their ability to control their brain activity, allowing them to effectively shift between mental states.

Traditionally, this type of training was expensive, with people often paying $15,000 or more for a limited number of sessions of clinical neurofeedback, in their attempt to improve health and performance and manage symptoms.

Mendi removes these limitations by offering the only true brain enhancement device that can be used from home. With Mendi, you can perform professional-grade neurofeedback sessions for a fraction of the price and as many times as you want.

Why Should You Train Your Brain

better performance

For Overall Health

Our overall health starts with our brain. Just like we look after our bodies, it’s important to keep our brains healthy. 

The brain affects every part of your body. Strengthening your brain and cognitive function can affect your physical well-being.

For Better Performance

A well-functioning brain is key to high performance. Brain enhancement training is used by many individuals and organizations to take their performance to higher levels, including:

Artists • Athletes • Entrepreneurs • Executives
Pilots • Academics • Esports • NASA  U.S. Special Forces • Students • Meditators 

Your brain function is essential to your mental and neurological well-being. Research using this technique has shown promising results in mental health and well-being. Current research is looking further into the potential of neurofeedback for various neurological and psychiatric disorders.

For Mental Well-being

Brain Training vs Mind Training

In their attempts to improve brain function, most traditional methods (excluding drugs) such as meditation, therapy, and mind exercises, all focus on training the mind in order to try to strengthen the brain. While it is possible to make some improvements to your brain by training your mind, it is significantly more effective to train your brain directly.

What do early users have to say about Mendi: 



AMAZING. INCREDIBLE. WOW. I honestly don’t know where to begin, I’m just very grateful. It’s the most important thing I have bought in my life.

In the Press

Here’s a peak at why experts are obsessed with Neurofeedback Brain Enhancement Training:

“Based on substantial neurological research, neurofeedback promises to make you more effective at learning how to control your own brain to minimize distraction or stay in a productive state of flow.”


“Neurofeedback has shown to be a clinically effective, non-invasive, non-pharmaceutical treatment method for a host of stress related health challenges: anxiety disorders, depression, migraines, fibromyalgia, ADD, and dyslexia, to name a few.”


“Patients with severe anxiety or ADHD are using neurofeedback instead of medications to change their brainwaves and help their conditions.”


“Neurofeedback aims to be more precise than current therapies. It directly targets the brain dysfunctions and emotional and cognitive processes that are understood to underlie psychiatric disorders.“


“The principle of neurofeedback is very simple. If you have a feedback about your cerebral activity, you are able to learn gradually to control this very activity.”

The Mendi Story

From an interest in improving their own brain, Mendi founders Sammy and Rickard got involved in professional brain enhancement training and soon after were running a leading neurofeedback clinic. 

Both felt it should not be limited to high income individuals who are able to pay thousands of dollars for a few sessions. With their strong engineering background, they decided to take the challenge of creating an easy to use brain enhancement device that is also affordable.

The team has since grown and has been joined by everyone from researchers and doctors, to designers and hardware experts, all of whom share a common goal of making brain enhancement accessible to everyone.

Despite major breakthroughs and triumphs, the Mendi journey has only just begun…

As a professional athlete, every tiny bit of improvement matters. With Mendi I had the biggest single piece of improvement.



I’m in college and have at least some level of ADHD (yes, just like everyone else). This training has done wonders to my concentration, truly amazing. I want to thank you guys for letting me in on your early user program.

When it comes to brain enhancement, Mendi is the answer.

I have been working as a yoga and meditation teacher for many years and I’m very keen on natural ways of improving my mental wellbeing. I was intrigued by Mendi because it uses modern technology to enable natural training. Since using Mendi I have been able to reach fantastic deep states which I have never been able to experience before and my students love it as well because it helps them get into a meditative state a lot quicker.



I have been blessed to be successful in my professional life as an entrepreneur and lately I have gained an increasing interest in improving my brain and performance. I started meditating about three years ago and I started going to a neurofeedback clinic in Santa Monica about a year ago. I have a very busy schedule and I travel a lot, so it’s not easy for me to visit a clinician regularly. I heard about Mendi from an investor-friend and thought it was worth giving it a try, without high expectations. Not too often I say this, but I was impressed. Now I bring my Mendi with me almost everywhere I go in my laptop bag.



My daughter and I are clients of their Brain Clinic in Stockholm, which have been completely LIFE CHANGING for both of us. I have been following Mendi’s development with incredible excitement and have been emailing Sammy almost on a weekly basis asking when we can get our very own Mendi :) Now our whole family (all 4 of us) are using Mendi regularly. What’s really funny is my husband was skeptical at first. Now he won’t start his day without first using Mendi ;)



Seriously, Mendi is unreal!!! I have been struggling with stress and broken sleep for many years. I have also had migraine for the last 2 years, which I believe has been stress-related. My first time using Mendi was a 15-minute session. That same night I could clearly feel a difference in my sleep. Since then I have mostly done 10-minute sessions and my sleep has completely transformed. I now sleep like when I was a teenager. Additionally my migraines seem to have vanished, at least I have not had any lately. It really feels unreal! never expected it to work so well!



I met Rickard and Sammy at a tech conference while visiting Sweden. They were both walking around with Mendi around their neck. I was able to try Mendi for a few min and thought it was the coolest thing In the world. I was later invited by Rickard to be be part of their early access program. Thanks guys, I really love my Mendi!



I was diagnosed with Anxiety and Depression. I have tried literally everything out there and nothing has worked for me. In best cases I have found temporary relief, but it either stopped working after a short period or the side effects became too strong to handle. Since using Mendi the changes I have experienced have been astonishing.



As a Biohacker & Tech Enthusiast, I love gadgets, especially within health-tech. I own all consumer Neurofeedback and Biofeedback products that have been released, as well as many other health related products. Additionally I have tried 20+ different Nootropics (smart supplements) as well as everything from cryotherapy to floating. I heard about Mendi through one of the Business Coaches at Sting (a startup accelerator that Mendi is a part of) and thought what they were doing was very interesting. I was able to get in touch with the team at Mendi and was later invited to be part of their early access program. As a Mendi user for almost one month now, I have to say I’m deeply impressed. The training is fun, yet powerful with a very clear effect. I usually do 12 minute training sessions. After each session I get a awesome feeling like I’m "ready for anything” haha. Can’t really use words to explain it, needs to be experienced. To sum up, it’s definitely the most powerful biohacking product I have tried and I look forward to each session. Really fantastic product :) I want to wish the Mendi team all the best of luck!




As a doctor I have been using Neurofeedback in my clinic for more than 5 years now, with +95% success rate. I wanted a real Neurofeedback device to give to my clients to use in between our sessions, so I was very excited when I heard about Mendi. After having used Mendi for almost 2 months now, I'm blown away. My patients are getting quicker results from Mendi than the in-clinic sessions. I started out hoping to use Mendi as a complement, now the clinic is a complement to Mendi.
