TU Delft Impact Contest
Stratos Dynamics
Our stratospheric glide aircraft start-up intends to addresses two 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.

CellaCure Technologies
Up to 400,000 adverse surgical outcomes are entirely preventable every year. Currently, 25% to 50% of malpractice cases stem from surgical errors, largely because surgeons must train on rigid, unrealistic plastics. Hospitals want to translate patient MRI scans into realistic soft-tissue phantoms, but current methods fail them. Traditional phantom labs rely on manual molding and casting, which is incredibly slow, unreliable, and cannot produce patient-specific anatomies. Meanwhile, commercial 3D printers cannot process complex medical hydrogels, forcing researchers into a 6-to-8-month "DIY" hardware nightmare that wastes up to €20,000 per project. This massive bottleneck drains budgets and keeps life-saving training tools out of the operating room, leaving surgeons underprepared and patients at risk.

Hydro-Guard
Protected natural areas face growing pressure from illegal exploitation such as poaching and illegal fishing. In many parks these activities are carried out by boat. For operators, boats are an important means of transport: faster than travel by land, independent of infrastructure, and capable of reaching remote areas. There are over 34,000 restricted-access protected areas worldwide. Out of our survey 90% struggles with boat-based exploitation, 87% of the parks are searching to improve boat monitoring. To date, there is no tool that maps boat traffic, even though it plays a dominant role in exploitation.

Spec2Solve
Researchers with deep domain knowledge waste time translating ideas into solver-ready optimization models: choosing variables, constraints, indices, and relaxations, then debugging feasibility and scaling. This “spec-to-code” gap causes slow iteration, fragile implementations, and modeling errors.

TangentAir
Nowadays, Air Traffic Control (ATC) manages airspace sectors, which can become crowded and cause delays. The current solution to this problem is manual command issues by the ATC, which is reactive to the situations. Moreover, with the technological advancements, Unmanned Aerial Vehicles (UAVs) and large drones are becoming more mainstream, meaning that the airspace will be even more crowded in the future. It is apparent that with the expected direction of advancement, a reactive solution to crowded airspace may be insufficient, which is what needs to be addressed.

Topper Talent
Engineering students at TU Delft often work underpaid jobs that don’t utilize their full technical skills, while startups and small tech companies struggle to find affordable, highly skilled talent for short-term engineering tasks.

NeuroLearn
Traditional education follows a one-size-fits-all approach, despite students having different learning speeds, strengths, and weaknesses. As a result, students often practice skills they have already mastered, while struggling areas remain insufficiently addressed. Teachers also lack scalable tools to personalize learning for every student. To compensate, many families turn to private tutors, who are often expensive and not always aligned with the specific curriculum or learning goals. This leads to inefficient use of time, unequal access to support, and inconsistent learning outcomes. An affordable, adaptive solution is needed to personalize learning at scale.

Samen Hypotheek
Students and recent graduates face an extreme shortage of affordable housing, making individual homeownership nearly impossible. While buying a home collectively with a group of friends is a viable solution, the financial, legal, and organizational barriers are incredibly high. Traditional mortgages and legal frameworks are not suited for multi-owner group structures. This leaves young adults locked out of the housing market, unable to build equity or secure stable living conditions during a crucial phase of their lives.

SkyRescue
Emergency situations such as fires, earthquakes, floods, and collapsed buildings often leave victims trapped in hard-to-reach or hazardous environments. Current response methods rely heavily on human teams and ground-based equipment, which are slow, risky, and sometimes unable to deliver life-saving aid quickly. Delays in locating victims and providing critical supplies reduce survival chances and increase danger for both victims and responders. There is a clear need for a rapid, adaptive, and airborne system that can reach inaccessible areas, assess the situation, and provide immediate support to save lives.
