Investments with impact

Health & life sciences

To improve the quality of life for current and future generations, we invest in various medical and life science start-ups. In doing so, we aim to make treatments and medications more effective and affordable, ensuring they are widely available and accessible.

Neuromuscular Electrical Stimulation (NMES) is a controlled electrical pulse aimed at nerves or muscle groups. These gentle pulses cause muscles to contract, resulting in the recovery of muscle strength.

Atlantic Therapeutics (acquired by INNOVO in 2023) uses this stimulation in various products to induce pelvic floor muscle contractions, training and strengthening the muscle group and giving the user better bladder control.

Heart failure is the number one cause of death worldwide. Current treatment options primarily alleviate symptoms and do not address the underlying causes.

The goal of Cardior (acquired by Novo Nordisk in 2024) is to develop RNA-based therapies to tackle the main causes of cardiovascular diseases.

Disruptions in the functioning of circular RNAs play an important role in the development of various brain-related diseases, such as autism spectrum disorders, depression, schizophrenia, and Alzheimer's disease.

Circular Genomics uses RNA biomarkers to promote accurate diagnosis and treatment of psychiatric and neurological disorders, aiming to arrive at an analysis and treatment plan earlier.

Immunic is a biotech company developing orally administered medications for chronic inflammatory and autoimmune diseases such as Crohn's disease and psoriasis.

In older age, a fall can take a terrible turn in our lives. Quick assistance after a fall is crucial. Preventing falls is even better.

Nobi is an AI-driven, life-saving care technology disguised as a stylish lamp that detects, prevents, and predicts falls, providing peace of mind for everyone.

Onward Medical aims to help people with spinal cord injuries enjoy life in a way that is important to them. To achieve this, they conduct research into ARC therapy, focused on stimulating the spinal cord through self-developed external or implantable technologies.

An acute ischemic stroke is a condition in which blood flow to the brain is disrupted by a blood clot in the artery, leading to oxygen deprivation, brain damage, and loss of function.

Perfuze promotes the treatment of ischemic strokes with technology that provides rapid and effective access to blood vessels, completely removing blood clots.

As the aging population rapidly increases, the risk of conditions such as glaucoma, Parkinson's, and multiple sclerosis also rises. Early detection of these diseases is crucial because they often develop asymptomatically while causing irreversible damage.

Reyedar addresses this issue by combining eye-tracking technology and deep learning to easily collect biomarkers of individuals' visual and neurological health. Eye movements are driven by a complex network of eye and brain structures. Subtle changes in eye movement behavior can indicate the presence of underlying medical conditions.

Cervical disc replacement is a surgical treatment option for damaged intervertebral discs in the neck. The procedure aims to reduce or relieve symptoms while preserving the mobility of the treated segment.

Simply Medical (acquired by NuVasive in 2021) develops the Simplify Cervical Disc for the most clinically effective total cervical disc replacements.

Sustainability

Investing in sustainability projects is essential for a healthy future. By opting for green initiatives, we reduce our ecological footprint, stimulate innovation, and contribute to a better world for future generations.

In traditional textile production, chemicals known as polymers are dissolved in water and then processed in fabrics using various complex machines. The problem with this process is that the chemicals applied with water are also washed away with water. These chemicals end up in wastewater, which is dangerous for our health and our planet.

Green Theme Technologies works with a water-free solution, based on natural building blocks such as hydrogen and carbon, to process textiles without generating harmful waste streams.

The plastic soup is a significant problem, especially affecting local populations in less developed countries. Their local ecosystems are polluted, and even if they manage to remove the plastic from the rivers, there is no sustainable solution for all that plastic.

RiverImpact addresses both issues by focusing on converting plastic waste into value for local communities. By intercepting waste in the rivers, they prevent it from ultimately reaching the ocean, and by sorting the waste, recyclable materials can regain value. One of the projects where they actively remove plastic from the river is the Motagua River in Guatemala, where about 50 truckloads of plastic waste are removed from the river daily.
