2022 WINNER in the Student category : 

Building the future of agriculture and agri-food with Hemeris

Co-founded by Steven Deves-Girain (E21) and Flora Vandier, Hemeris aims to build to a more environmentally-friendly agro-industry, thanks to the development of an innovative and sustainable solution for seed treatment based on cold atmospheric plasma. As an alternative to widely-used chemical compounds, Hemeris focuses on decontaminating and enhancing the water absorption of seeds. Hemeris has two industrial and customer partners, Germine and Gautier Semences.

A dual graduate of ESSEC and CentraleSupélec, and son of a vegetable farmer, Steven has always had a vested interest in building a responsible agro-food industry. 

“At present, the industry uses a long and complicated disinfection process involving chloride compounds. We’re entering a 4-billion-euro seed market. Our target is seeds and grains of very high added value.”  

The deeptech Hemeris works hand in hand with Geeps, IPS2 and LGPM, 3 laboratories in the Paris Saclay ecosystem. The start-up is supported in its entrepreneurial growth by ESSEC, 21st by CentraleSupélec and Agro PariTech. 

“Our roadmap for 2022 is the diversification of laboratory applications; in 2023 we’re aiming to set up the first pilot projects for a customised decontamination of seeds and grains, and 2024 should see the roll-out of decontamination units for our industrial customers.” 

Winner 2022 in the Alumni category :

Vestack evolves in the construction industry

Co-founded by Nicolas Guinebretière (E17), Jean-Christophe Pierron and Sylvain Bogeat, Vestack is a technological platform for digital design (BIM) and industrial building (modular 3D in wooden frameworks) which reconciles carbon requirements and the profitability of real estate developments. Vestack designs and constructs buildings which cut CO2 emissions in three and halve lead times, at no extra cost.

“The building sector currently represents €100 billion in turnover for France, €1,000 billion in Europe, and contributes to more than 25% of the world’s CO2 emissions. Vestack is a new solution which offers an integrated vertical model with 3 innovative technologies: a software programme, a modular building system and an integrated industrial model with low CAPEX.” 

Vestack opened its first plant near Meaux, and is due to open a second factory in the coming months in Seine-et-Marne, creating some forty new jobs to meet the demands of the catchment area.

“The real issue is not the demand, which is huge, but the ability to develop production plants. Vestack hopes to exceed €10 million in turnover next year.”
