The 10 startups below
01
Spacetech · Deeptech
Edge Aerospace
edge-aerospace.com →
Founder(s)Jaroslaw Jaworski
Funding€1M
LocationLuxembourg-City Incubator

Spacecraft generate more data than they can move. Edge Aerospace builds the data-processing systems and network switches that fix that — high-bandwidth links between payload sensors and processors for real-time in-space analytics. Screened off-the-shelf components keep costs down without sacrificing mission-grade reliability. The plumbing satellites didn’t know they needed.

Happy Kids Academy
happy-kids.lu / happykids.ai →
Founder(s)Luanna Eroles
FundingUndisclosed
LocationSocial Business Incubator

Kids’ mental health support shouldn’t be an afterthought. Happy Kids Academy’s AI-powered platform builds children’s and teenagers’ resilience, emotional literacy, and wellbeing — edtech and healthtech in one. Prevention, not just intervention.

03
Spacetech · Robotics
Lunar Outpost

Founder(s)Justin Cyrus, Forrest Meyen, AJ Gemer, Julian Cyrus
Funding$39M
LocationTechnoport

The Moon needs mobility. Lunar Outpost builds space robotics and lunar rovers — autonomous vehicles like MAPP and NASA’s Artemis LTV programme — delivering mobility-as-a-service for scientific and commercial payloads in extreme environments. Luxembourg’s link to the lunar surface.

Mobility · SaaS
Optryt

Founder(s)Antonio Da Palma Ferramacho, Rose Thattil Candeth
FundingUndisclosed
LocationTechnoport Automobility Incubator

Fleet leasing still runs on spreadsheets and phone calls. Optryt’s SaaS platform, LeaseRyt, standardises the process — structured RFQs, offer comparison, and document management for fleet owners, leasing companies, and dealerships. Data-driven automation for an industry that’s overdue for it.

05

StrayProtect
list.lu/ventures/strayprotect →
Founder(s)Naoufal Bahlawane
FundingPre-Seed (ESA), ~€2M raised in total
LocationA LIST spin-off

Stray light ruins optical performance — StrayProtect eliminates it. The LIST spin-off applies ultra-black nano-coatings to complex 3D parts, a process purpose-built for aerospace and optics makers. Backed by ESA. Ultra-black, ultra-precise.

06
AI · Voice
Subphonic
subphonic.ai →
Founder(s)Matthew Bryars
Funding€1.3M (2024) + £10M (2026)
LocationLe Village by CA Luxembourg

Most conversations still disappear the moment they end. Subphonic turns voice and audio into structured, actionable data — transcribing, analysing, and surfacing insight to sharpen operations, compliance, and decision-making. Two raises in two years. Voice AI with a business case attached.

07
AI · Enterprise
TeamIA
teamia.ai →
Founder(s)Christian Michel
Funding120K€
LocationInnovation Hub Dudelange

TeamIA builds sovereign AI agents for ambitious companies across Luxembourg and the Greater Region. Fit4AI and SME Package AI accredited — from AI diagnostics to deployment.

08
Healthtech · Forensics
Unknown Labs
theunknownlabs.com →
Founder(s)Bradley Elsbury
FundingUndisclosed
LocationHouse of BioHealth

Forensic identification still moves too slowly. Unknown Labs is building the global intelligence network for it — connecting spectrometers across institutions and borders so substances are identified in seconds and emerging threats spotted as they spread. House of BioHealth gives it the ecosystem to scale.

09
Biotech · Defence
USIL Therapeutics
usil-therapeutics.com →
Founder(s)Fred Marin, Bruno Le Grand, Bruno Flamion, Michel Andraud, Valentin Wiedling
Funding5,2M€
LocationLuxembourg-City Incubator

Nuclear and radiological preparedness has a capability gap — across defence, civilian, aerospace, and space. USIL Therapeutics is developing whole-body radioprotective medical countermeasures for rapid institutional deployment, built from Luxembourg’s central position in the EU, aerospace, and NATO procurement ecosystem. Protection before, during, and after exposure.

Zetako

Founder(s)Jonas Hamou, Marc-Antoine Augugliaro, Claus Rosenberg Gotthard, Girish Dadheech
