Startups in Grenoble: ecosystem, companies and strengths
Europe's deeptech capital: 475 active startups, 44% deeptech, 4th European capital for deeptech development.
Why Grenoble matters in the European startup ecosystem
Grenoble is Europe's purest deeptech ecosystem: 'French capital of deeptech', 4th European capital for deeptech development and European Capital of Innovation 2026. With 475 active startups in the Grenoble Alpes area, 44% of which are deeptech, and around €4 billion raised in the past three years, the city hosts some of Europe's biggest spin-outs in semiconductors (Aledia), battery energy (Verkor), quantum computing (Quobly) and edge AI (GreenWaves). CEA-Leti is Europe's most prolific public laboratory for deeptech startups.
Why it works
- Structural technology transfer
- Very clear verticals
- Excellent research-industry alignment
Historical growth
Grenoble is one of the best European cases of territorial deeptech. It has built solid growth through applied research, semiconductors, batteries and scientific spinouts.

Quobly
Quobly industrialises silicon-based quantum computers using semiconductor manufacturing processes.
Strengths of Grenoble
- Exceptional cluster for semiconductors and materials
- High scientific quality
- Excellent technology transfer
- Seed and early deeptech stages are well served by specialist actors. The main problem remains financing the more expensive industrial stages.
- Semiconductors, batteries, energy and medtech offer demand consistent with the city's profile. Grenoble works well when a product is born in a lab and immediately finds industrial applications.
Weaknesses and limitations
- Small local market
- Lower visibility than Paris
- Startups often very capital intensive
Key startups in Grenoble
Aledia
CEA-Leti Grenoble spin-out developing microLED technology on gallium nitride nanowires for AR/VR displays, wearables and high-efficiency screens.
ENGO
A French company developing lightweight Micro-OLED smart eyewear for endurance athletes.
Hprobe
Hprobe is a research spin-off based in Grenoble, founded in 2017 and now a Mycronic division. It makes automatic wafer-level test systems for magnetic devices (MRAM, magnetic sensors) for foundries and semiconductor labs. Its patented technology manages three-dimensional magnetic fields for precise testing, making Hprobe a global leader in magnetic testing.
Mantle8
Mantle8 develops proprietary geological exploration technologies to locate and access natural hydrogen deposits underground — a potentially abundant clean energy source not yet commercially extracted at industrial scale.
Quobly
CEA-Leti and CNRS spin-off based in Grenoble developing silicon quantum computers compatible with industrial 300 mm wafer processes.
Renaissance Fusion
Renaissance Fusion (Grenoble) is a deeptech startup focused on nuclear fusion energy. It uses extreme-power lasers and advanced techniques to trigger controlled fusion reactions more efficiently and safely. Partnering with European research institutes, it aims to demonstrate the feasibility of a laser-driven fusion reactor.
Spartoo
Spartoo is an online retail site founded in 2006 in Grenoble. Specialized in fashion and footwear, it offers millions of items from over 1,000 brands, shipping across Europe. The startup has millions of registered customers and over €100M in annual revenue. In 2019 it was acquired by the OTB Group to expand its presence.
Verkor
Grenoble scaleup developing and manufacturing high energy-density lithium-ion batteries for EVs and storage, with a gigafactory under construction in Dunkirk.
WIZBII
WIZBII is a French social network (Grenoble) dedicated to students and recent graduates. Founded in 2011, it helps young people find job opportunities, internships and training, with features such as video CVs and career advice. It is used by schools and companies in France for recruitment and career mentoring.
