We support these startups in their seed phase, to accelerate their commercial development, refine their roadmap, and their go-to-market strategy. They benefit from strategic support from our partners AgroParisTech or Ramsay Santé, hosting at STATION F or on the Paris-Saclay campus, mentorship, access to our funding tools, our alumni network, as well as CentraleSupélec and AgroParisTech research laboratories.
The 21st by CentraleSupélec accelerator has supported 45 startups since 2021, with 83% of them successfully raising funds from investors to fuel their growth.
Meet this new cohort!

🐻 CareCare | Co-founders: Daniel Benamran, Simon Roquette
In just a few years, home care has become France's primary hospital – in 2022, home care services supported approximately 2.5 million patients annually, a figure that has tripled since 2010 and continues to grow, and existing software is poorly suited to the experience of home healthcare professionals.
To address this, Daniel and Simon developed CareCare, an OS (Operating System) for home healthcare, entirely dedicated to independent nurses (IDELs), aiming to centralize their administrative tasks, to allow them to save up to 7 hours of work per week. The ambition of CareCare is to place independent nurses at the heart of the home healthcare system, with an application tailored to the reality of their daily lives. This will enable better quality of care for patients, and a better work-life balance!
Next objective: to raise 1.5 million euros in seed funding, and to launch the SaaS application in early 2025!

🏭 Entalpic | Co-founders: Alexandre Duval, Victor Schmidt, Mathieu Galtier
Entalpic's ambition is to sustainably transform the chemical industry and enable it to make significant advances in sustainability and environmental impact.
Co-founded by a trio of French AI and machine learning experts, Alexandre, Victor, and Mathieu, Entalpic is reinventing the discovery of materials and molecules for a more sustainable future. Their advanced AI platform designs catalysts to optimize chemical processes in areas such as energy storage, fertilizer production, and pollution control, by combining open and proprietary research, thereby filling a market gap with manufacturing processes that ensure reproducibility.
On September 5th, they announced a funding round of €8.5 million, led by Breega, Cathay Innovation, and Felicis.

🏡 Kelvin | Co-founders: Clémentine Lalande, Pierre Joly, Guillaume Sempé
Thermal issues are common in old buildings due to outdated infrastructure and poor insulation, making it difficult to maintain a constant temperature for residents.
Kelvin's mission: to enable construction and real estate professionals to effectively support energy renovation projects for individuals. Thanks to AI and computer vision, Kelvin remotely assesses a home's energy performance and generates quantified and personalized work recommendations for a guaranteed improvement in the DPE (Energy Performance Diagnosis). Kelvin offers a revolutionary experience for qualifying energy renovation projects, simply by using the address and photos of the property.
Kelvin recently raised 5 million euros, led by Racine² - let's go! 👏

💡 Lumisync | Co-founders: Giuseppe Modica, Alexis Jonville
The microelectronics is no longer progressing fast enough in terms of performance and energy consumption to satisfy cutting-edge industries (5G/6G, AI, Quantum, etc.).
Co-founders of the startup Lumisync, Giuseppe and Alexis provide the missing piece to this puzzle by commercializing the world's first 100% photonic oscillator, a component that allows integrated circuits to synchronize data at the speed of light. This oscillator enables very high-frequency data synchronization with high stability, while being extremely compact, 1000x more energy-efficient, and 1000x faster.
Lumisync was selected as one of the three most promising startups at the 2024 edition of SPRING 50.
Next objectives: reach the Industrial MVP stage, sign their first clients, and complete their seed funding round.

🔋 Revolty | Valentin Heuzé, Mathilde Janicot, Julen Urchoeguia
Traditional batteries pose several environmental and economic challenges; their manufacturing requires rare raw materials such as lithium and cobalt; their recycling is complex and expensive; and their production is costly and energy-intensive.
With Revolty, Valentin, Mathilde, and Julen aim to address these challenges. Revolty aspires to giving a second life to lithium batteries from electric mobility, to store electricity for solar panel owners. And thus develop a solar storage solution that is finally affordable and sustainable for all solar panel owners, so they can freely consume everything their panels produce. Their first prototype is currently in production!
Next objectives: secure the necessary funding for prototype development, establish a clear and long-term product roadmap (prototype + industrial phase), and achieve technical-industrial proof of concept for the product.
