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.

Electric bikes are becoming increasingly popular, but they still have several major barriers: High cost – Many electric bikes are too expensive for students, young adults, and people on a budget. Limited customization – Users cannot easily customize their e-bike to match their needs or preferences. Complex assembly – Converting or assembling an electric bike yourself can be difficult without the right system or guidance. Battery concerns – Users worry about battery life, performance, and reliability. Security risks – Bike theft is common, and many bikes lack integrated GPS tracking systems. Lack of integration with smartphones – Many bikes do not offer a simple mobile app to track location, battery life, or performance. These barriers prevent many people from accessing sustainable electric transportation.

Routly
Supply chains are under real pressure right now. Geopolitical uncertainty is making operations unstable, and costs keep rising. Every extra mile costs money. Also no vehicle route planning platform on the market can do real-time reoptimization today. That's a gap we're excited to close.

Current air and ground freight systems use fossil fuels that create a lot of greenhouse gases and are expensive. Planes and trucks burn fuel quickly and can’t fly long distances without refueling. This makes transporting heavy cargo over long distances costly and bad for the climate, and current electric systems still struggle to match the range needed for large freight.

Heavy duty vehicles being only 4% of the transportation market contribute to more than 25% of the global emissions. With existing solutions for light vehicles not applicable for the heavy duty market, a new architecture is needed to meet zero emission targets without compromising operational demands. But achieving zero emission targets isn’t a day’s work, and therefore needs a solution that can adhere to the future changes and challenges to the advances in the types fuels. Hydrogen today. Synthetic fuels tomorrow and the industry can’t afford to reinvent propulsion everytime.

Windsight
Offshore wind turbines are critical to Europe's energy transition, yet blade maintenance remains one of the industry's most costly and dangerous challenges. O&M costs represent 30% of a turbine's total lifetime expenses. Current inspection regimes are either periodic (conducted regardless of actual asset condition) or reactive, responding only after damage escalates. Sensor data and drone inspection data exist isolated, neither informing the other. The result: unnecessary vessel deployments, missed early-stage damage, unplanned downtime, and avoidable emissions from offshore crew transfers. The industry lacks a diagnostic intelligence layer to tell operators precisely when and where to act.

When medical emergencies occur, teams of first responders need specialized medical equipment and supplies to be able to administer life-saving treatments. This equipment cannot always be carried by first-responders, as emergency situations are unpredictable and the aid required can only be truly assesed on-site. Existing land-based transportation solutions are vulnerable to infrastructure-related issues: congestion, maintenance or accidents can lead to delays which directly impact patient survival rates and can lead to avoidable complications. A more resilient solution is thus desirable.

Over 50% of domestic pets suffer from obesity or chronic conditions that go undetected until they require emergency care. The "Care Gap" exists because current smart feeders are merely automated timers, they cannot track the physiological state of the pet. Owners lack a non-invasive way to monitor vital signs like respiratory rate and heart rhythm during feeding. This leads to late-stage diagnosis of metabolic and cardiac issues. We are addressing the need for a proactive health-monitoring system that integrates medical-grade physiological sensing into the daily feeding routine.

We need an underwater drone that can fit inside a backpack, be cheap and easy to repair, and allow for many modifications to be made in the field (such as a robot arm or flashlights in modular configurations).

NeuroType
Individuals with severe motor impairments or speech loss (e.g., ALS or paralysis) often face "locked-in" conditions where traditional communication tools like eye-tracking are too fatiguing or physically impossible to use, leading to social isolation and a loss of autonomy.
