Aerial delivery has been discussed for a long time, but significant advancements in this technology have yet to be made. Aerial delivery is particularly useful for reaching hard-to-access areas, such as islands and deserts. However, the current challenge is that the costs often outweigh the benefits. At present, drones are the most viable option, but they do not justify their price given their limited range and flight time. The issue is not with the power source; rather, it's that drones must generate both thrust and lift from their rotors, which makes them inefficient.

Lente Health
Therapists across Europe are overworked, burnt out, and too much of their day is spent on non-clinical tasks.

Cognitive health is an increasingly critical concern. More than 55 million people live with dementia, a number expected to nearly double by 2050, with Alzheimer’s disease accounting for 60–70% of cases. While age is the strongest risk factor, especially after 65, cognitive decline is not a normal part of aging. Declining cognitive health significantly impacts daily functioning, making it difficult to manage quotidian tasks. Addressing these challenges requires effective, accessible solutions that support memory, safety, and autonomy in everyday life.

We live in a time where we are more connected than ever, yet many people feel deeply disconnected. Somewhere along the way, we forgot that the world is our playground. Even when surrounded by others, it’s easy to feel alone, stuck in routine, and unsure how to step outside it. Many want to try new things, meet people, or simply feel more present, but taking the first step feels awkward or overwhelming. There is a growing need for simple ways to rediscover curiosity, spontaneity, and human connection in everyday life.

Emergency services, especially fire brigades, often lack fast, reliable aerial awareness that regular crews can deploy and operate with minimal training. Today’s quadcopter drones used in emergencies are often expensive, limiting availability across brigades, and typically fly only 30-45 minutes, forcing frequent, time-consuming battery swaps during critical incident phases. They also struggle to cover larger areas and usually require constant pilot attention, while helicopters are costly and not always available. The result is delays and blind spots in tracking fire spread, locating hotspots, and searching for missing people - so crews sometimes abandon drones when they become impractical.

Anxiety and panic don’t wait for therapy appointments. When stress spikes, people often lack an immediate, private, and effective way to downshift their nervous system—especially in public, at work, or in the wild. Current tools (breathing apps, meditations, fidgets) require attention and time precisely when attention is scarce. Weighted blankets and hugs help, but they’re not portable or “on-demand.” Meanwhile, wearables detect stress signals, but rarely translate that data into fast, embodied relief. The need: a discreet, rapid, body-based intervention that can activate at the right moment.

Bij werkzaamheden aan dijken en spoorleidingen ontbreekt vaak voldoende inzicht in wat er onder en rondom de grond gebeurt. Dit brengt risico’s met zich mee voor de veiligheid, het monitoren van de infrastructuur en de planning van graafwerkzaamheden. Daarnaast kunnen dieren zoals bevers en dassen worden verstoord of raken hun burchten beschadigd, wat zowel ecologische als logistieke problemen veroorzaakt voor dijk- en spoorbeheerders.

Painting large surfaces is an expensive, logistically complicated, time consuming, physically demanding, and dangerous job. Individuals and companies in large scale painting industries rely on scaffolding, lifts, and long hours, leading to risk of injury.

Stratos Dynamics
Our stratospheric glide aircraft start-up intends to addresses three primary challenges on a phased basis: 1. Current atmospheric data collection relies on single-use weather balloons that drift unpredictably and who’s sensors are rarely recovered. This creates pollution and results in increased costs. 2. Existing satellite infrastructure is prohibitively expensive and rigid, making it difficult to integrate rapid changes in sensor or communication technology.

IonVe - Electrochemical Reactors
Electrochemical energy systems, especially redox-flow batteries for stationary energy storage and electrolyzers, face a scalability bottleneck driven by complex, costly, and poorly optimized reactor (stack) architectures. Despite major investment and advances in chemistry, many designs remain direct scale-ups of laboratory hardware, relying on graphite/metal parts and multi-component assemblies that constrain design freedom, increase cost, and hinder manufacturability and rapid iteration. As a result, performance and reliability fall short of their true potential, delaying industrial adoption and large-scale deployment of energy-storage and conversion technologies.
